Abstract: وظفت تقانة زراعة الانسجة لاكثار نبات Spilanthes acmella (L.) Murr. كونه نباتا غير مستزرع في العراق ولاهميته الطبية والزراعية بوصفه نبات زينة فضلا عن استعمالاته الاخرى. عقمت البذور بمادة هايبوكلورات الصوديوم(NaOCl) وزرعت على وسط Murashige وSkoog (1962) (MS | The technique of plant tissue culture has been manipulated to In vitro micropropagation of Spilanthes acmella (L.) Murr. It is an ornamental and medicinal plant not cultivated in Iraq. Seeds were sterilized by sodium hypochlorite (NaOCl) and cultuared on full strength Murashige and Skoog medium(1962) (MS). Nodal segments, apical shoots, and leaflets explants were taken from seedlings and cultured on (MS) medium enriched with different concentrations of Indol acetic acid (IAA), Naphthalene acetic acid (NAA) Benzyl adenine (BA), and 6 - furfurylaminopurine (Kin.). The study include the effect of node orientation vertically and horizontally on induction of shoots formation. The effect of the interaction between IAA and BA, IAA and Kin. on shoot multiplication was investigated. Rooting was also studied after inclusion of IBA and IAA to full and half - strength (MS) medium. At acclimatization stage, different ratios of river sand and peat moss as agricultural media were tested and plantlets survival was recorded. DNA isolation was carried out from fresh and dry plantlet leaves as well as from seeds and Agarose Gel Electrophoresis (AGE) was done. Results showed that 1.5% sodium hypochlorite for 15 min was very effective for disinfecting and survival. The nodes cultured vertically exhibited relatively highest response as compared with apical shoots and leaflets culture. Supplying the culture medium with 1 mg/L. BA was effective for lateral shoot induction. The mean number of shoots obtained from nodes were 7.43 with a mean length 0.9 cm. Adding IAA at 0.1 and Kin. at 0.5, 1.0 or 1.5 mg/L. to the growth medium was effective for multiplication. Mean number of the developed shoots were 12.00, 14.20, 13.60 shoots/ explants with a mean length of 3.40, 2.60, 1.40 cm, respectively. Adding 0.1, 0.5, 1.0 mg/L IBA to the half strength MS medium was very effective in root formation which produced 45.0, 42.5, 40.0 roots, respectively, with mean length of 3.25, 3.80, 3.80 cm, respectively. Plantlets were acclimatized successfully achieving 100% survival after four weeks when transferred to agricultural medium consisted of river sand and peat moss at 1 : 1 v/v ratio. This study showed the ability of in vitro micropropagation of Spilanthes acmella (L.) Murr. DNA isolation from drying leaves was butter than fresh leaves with the precense of liquid nitrogen.

Four stations were selected for sample collections over the distance of 25 km. Two stations were in Tigris river and two were in the treatment unit. The first selected station was close to the old water purification unit in Tikrit - city. The second station was selected at the treatment unit in AL - Dubaee before the mechanical treatment unit. The third station was selected at the treatment unit after the biological treatment. The fourth station was selected in Tigris river about ten km south of the treatment unit at AL - Dijla town. The study involved an investigation of some physical, chemical and biological aspects of Tigris river and the residence waste discharges to the river. This included air and water temperature, conductivity, PH, dissolved oxygen, BOD, Turbidity, total hardness, calcium and magnesium hardness, chloride, total alkalinity, nutrients (i.e., phosphate, nitrite, silica) , and the concentrations of heavy metals (i.e., cadmium and cupper). The biological factor included the total bacteria counts cultured on nutrient agar. Results of the study clarify the close relation between air and water temperature which varied (8.5 - 36) C0 and (9 - 27) C0 respectively. Conductivity values were relatively high and ranged (128 - 3530) microsemens/cm. River water almost was alkaline during the period of the study. PH values of the first and fourth stations were close in the river, although a value of 6.12 was recovered at station on during May. In all stations, PH values ranged (8.8 - 6.12). River water has a good ventilation, dissolved oxygen values ranges (8 - 11) mg/L at the first and the fourth stations, while these values were (0.1 - 1.34) mg/L at the second and third stations. Mean dissolved oxygen values pointed out the availability of good oxygen concentration for the continuity of living organisms which ranged (0.3 - 5.8) mg/L in Tigris river, while BOD values at the stations second and third were high and ranged (5.6 - 131.2) mg/L. Turbidity was high during April at the stations one and four and ranged (2.03 - 788) NTU in all stations. Total hardness in Tigris river was slightly low - very hardness and ranged (120 - 360) mg/L at the first and fourth stations, while these values were (180 - 480) mg/L at stations two and three.The high total hardness values coincided with the high conductivity values. Concentrations of calcium ions responsible on the calcium hardness ranged (211.4 - 120.7) mg/ L was higher than magnesium ions responsible for magnesium hardness range (5 - 265) mg/L.Records of chloride ions ranged (14.16 - 169.99) mg/L at all stations. However, chloride values at stations first and fourth were among the allowed world values and ranged (14.16 - 42.48) mg/L.Alkalinity values were due to the carbonate and bicarbonate and ranged (35 - 725) mg/L.phosphate values ranged (0.168 - 25.2) µg phosphor atom - phosphate/L. Low nutrient values recorded in Tigris river, while the highest values recorded at second station (treatment unit).Nitrite values fluctuated at all stations and ranged (0.078 - 14.778) µg Nitrogen atom - Nitrite /L. Silica values ranged (648 - 5961.6) µg silicon atom - silica /L. Heavy metals values (Cadmium and Cupper) clarify that, Cadmium were (un sensible), except one value (0.008) mg/L that recorded at November, and un sensible for Cupper.Results of the statistical analyses of all involved factors showed significant differences at stations first and second, and between the first and third stations as well as the fourth station. While there was no significant differences between the second and fourth stations. And no significant differences between stations first and fourth.Total bacterial counts indicated high bacterial counts, and the average of total bacterial count ranged (2.605X105, 5.44X108, 2.265X108, 2.385X105) / ml at the four stations respectively, so the Tigris river considered pollutant - very pollutant.

The stage of work had been done by cultivated the seeds of two cultivars of wheat (Sham - 6, Abu - Ghraib) in pots, when they reached the stage of (4 - 5) leaves it had been exposed to two dryness periods 7 and 10 days. It spread with growth regulator Indole Acetic Acid (IAA) (150 ppm) to know which type is more resistance for dryness through estimation of proline concentration as a physiological marker and to indicate the effect of IAA to reduce the dryness effect in some features of growth physiological function and yield component according to complete Randomize Design (CRD). Some markers of drought tolerance have been estimated including : proline content, chlorophyll concentration and the degree of membrane stability then plants were left for harvesting period. The results of the outdoor experiment were : 1 - Exposure the plants to dehydration periods during their growth caused reducing of the most studied characters (leaf area, plant height, tillers number, concentration of chlorophyll A and B and the total chlorophyll), while there was an increase in the content of the proline and the injury index of plasma membrane. 2 - Some characteristic did not showed effect by drought periods (dry weight of plant, number of days of flowering, spikes number, spike length, number of grains/ spike and weight of 1000 grains).3 - Sham - 6 cultivar was superior than Abu Ghraib - 3 in three characteristic (number of days of flowering, leaf area, weight of 1000 grains), while Abu Ghraib - 3 cultivar was superior in the grains number /spike than sham - 6 cultivar.4 - The concentration of IAA (150 ppm) had a different effect. It had a positive effect in the decrease drought for some characteristic (proline content, injury index of plasma membrane, leaf area, plant height, dry weight, spike number and grains yield).2 - Genetic part : DNA has been isolated from fresh leaves of two types of wheat, arrange yields of DNA were in the range of (40 - 150) micro gram per 1.5 gram of plant leaves, and the purity ranged between (1.2 - 1.7). The reaction PCR was done by using 11 primer of the Random Amplified Polymorphism DNA (RAPD) in addition to two pair of specific primer to detect the genes which are responsible for coding of two enzymes which involved in anabolism and catabolism of proline. The results obtained are as follows : - 1 - Five primer of RAPD did not appear any binding site (OPA - 18, OPL - 20, OPA - 11, OPQ - 17 and OPH - 14).2 - Six primer of RAPD have appeared main and monomorphic bands (OPO - 16, OPH - 07, OPN - 16, OPM - 20, OPJ - 13 and OPQ - 06), in addition to the absent of the other bands from some treatments. 3 - The two pair of specific primer have given three monomorphic bands with different molecules weight.4 - The primer (OPH - 07) has appeared a unique band with molecular weight (1670) pb for Sham - 6 cultivar during second drought period (10 days without hormone). These results obtained from this study were identical with physiological part in the ability of both types to drought tolerance

Abstract: تناولت الدراسة الحالية, دراسة مظهرية وتشريحية مقارنة لـ(10) انواع تعود لـ(9) اجناس من العائلة المركبة Asteraceae (Compositae) في العراق, كما وتبعت الاجناس قيد الدراسة الى عشيرتين Tribes : العشيرة الاولى : (Cardueae), وقد ضمت الانواع : (Arctium tomentosum, Ca | The current study dealt with the morphological and anatomical aspect that compared the (10) Species that followed (9) genera, These Species followed the family Compositae (Asteraceae) in Iraq. It also divided the genera under study to two tribes. The first tribe : (Cardueae), It included the Species : (Arctium tomentosum, Carlina vulgaris, Chardinia orientales, Cnicus benedictus and Notobasis syriaca). The second tribe : (Lactuceae), It included the Species : (Geropogon glabrum, Geropogon hybridus, Hedypnois cretica, Koelpinia linearis and Urospermum pecroides). The morphological study involved the roots according to the characteristics, the form and dimensions (the length and the diameter), the study of the stem by the character, the color and the indumentums, also the dimension (the high and diameter) it resulted good characteristics, enabled us to use it in isolation of the types. It is also discussed the leaf on the based of the quantifier and qualifier that involved the form of the leaf and the form of the peak and the base, the character of the blade margin and the epidermis. The study also high lighted the dimension of the blade (the length and the width), The morphological characteristics of the leaves have given a great Taxonomical value rather than the root and the stem. It also mentioned in this study the Inflorescences in general : the form and the diameter of the receptacle, the dimension of the inflorescence (length and width), and the characteristics of the phyllaries, the study of Achenes, the length of the beak, the character of the filaments that connected by the peak of the beak. The proper morphological characters of the Inflorescences made the contrastive among the characteristics of the Inflorescence in unique type. This great advantage is useful in the classification of the species. The anatomical study contains the study of the dermal tissue system that belong to the types under study, specially the stem, the leaf. It make clear the differences among the characters of the epidermis cells for the stem and the leaf (the upper and lower epidermises), It tackled the study of the Stomata at the leaf and the stem, and measure of the frequency at these members. It also discussed the fundamental and vascular tissue system of the root, the stem and the leaf through the study of their characteristics of the transversal sector. It is also studied the vascular bundles according to the thickness of the regions belonged to the xylem and phloem; the number of the xylem arms in each bundle and the number of the vascular elements in one xylem arm. The study involves the system of the veins into the leaf blade or that called (Venation), and the thickness of the veins and its course, the behavior of the vein's ends and the method of its contact with the leaf margin. In addition, the study dealt with the method of the joining veins the secondary by the primary and the third veins by the secondary. Thus, the study make clear the considerable advantages that distinguish the types each other. It is observed the characteristics of the leaf's venation is a constant character that depends upon to classify the species. At end of the study, It is used the results of the morphological and anatomical characteristics in comparison of the two tribes; Cardueae and Lactuceae that the studied species followed.

Abstract: This study examined the current survey of the vascular plants of dicotyledon wild during the study period (2013 - 2012) In the area of Sudoor - Diyala, the study was based on the 774 samples of plants with their duplicates as collected by The Researcher. All of these collections have been cacched in the Iraqi herbariums. To be specific there are 186 species which relate to 133 genus and 43 families. All these, have been scientifically classified with thier local and common Iraqi or arabic names.Besides, their duration and economic importance (medical, toxic, nutritional or forage, artificial, harmful, aromatic, ornamental, fuel plants or other uses). Moreover, their geographical distribution in the districts of Iraq and thier geographical existence in neighboring countries to Iraq (Saudi Arabia, Kuwait, Turkey, Iran, Syria and Jordan) , and the study results statistics have shown that the vast majority of the collected species are Herbal Plants totalling 164 species out of 179 species in all.This, in fact, can be ascribed to the impossibility of txonomizing 7 plants species for the incapacity to obtain their flowers or fruits. As for the shrub species it amounts to 13 species where as the number of woody species of trees is 2 only. As for the economic plants and their significance, let s mention the fact that the number of plants used as forage amounts to 86 species, the medical plants are 83 species, the toxic plants fall into 43 species, the ornamental plants are 23 species, the industrial plants are 14 species, the weed plants are 11 species, the aromatic plants are of 6 species, and the plants used as fuel are of 4 species. It also appears that the majority of the plant in the area of study is widespread in the various districts of Iraq, i.e. the number of such plants amounts to 110 species, however, there are plants of medium spread in the districts of Iraq, i.e. the number of such plants amountsto 54 species.There still are some plants whose geographic distribution has no been identified in the districts of Iraq and their number is 15 species, and as for their geographic extension into the neighboring Countries, these plants amount to 116 species in Saudi Arabia, 84 species in Turkey, 81 species in Iran, 79 species in Kuwait, 69 species in Syria and 26 species in Jordan. Furthermore, the species of plants collected perviously and have not been found during the period of study amount to 32 species and these relate to 13 families.The shrinkage of the vegetation cover in the area of Sudoor is attributed mainly to the drought conditions and the wind soil erosion which the area has undergone in the previous years. Besides, there are some other reasons including the overgrazing, the expansion of agriculture and the unstudied projects of construction, which have resulted in the disappearance of natural plants in the area.

The two experiments were conducted at the field of College of Agriculture/Al - Qadisiya University during the period from 31/10/2012 to 14/3/2013. For the field experiment, dry and fresh leaves of Eucalyptus were used at the rate of 0, 2, 3, or 6 g dry leaves/Kg soil or at the rate of 0, 4, 8, or 12g fresh leaves/kg soil. Plant height, changes in height during plant life time - course, number of branches, number of flowers, and flower diameter were measured. In addition, chlorophyll content in leaves, anthocyanin in petals, dry weight, nitrogen percent, potassium and phosphorous content in leaves were also determined. For the laboratory experiment, ethanol extract, oil, terpenes, alkaloid, and phenols extracted from Eucalyptus leaves at different concentrations were used. Seed germination, coefficient velocity of germination, plumule and radical length, sugar, protein, melanodialdehyde, glutathione and proline content were evaluated. The results were as follow : 1. Ethanolic extract was negatively affect the percent and coefficient velocity of germination in addition to plumule and radicle length. The reduction in these parameters was greater at the highest concentration of the extract, especially in Calendula officinalis. 2. Treatment with oil extracted from Eucalyptus leaves caused a significant reduction in percent and coefficient velocity of germination, plumule and radical length. 3. Terpenes, alkaloids or phenols treatments at different concentrations resulted in significant reduction in percent and coefficient velocity of germination, plumule and radical length. The reduction was increased as the concentration of the treatments increased. 4. Plant height decreased significantly due to the treatment with dry or fresh Eucalyptus leaves, the reduction in plant height increased as the concentration of the treatment increases in all plants except Asteriscus graveolens plant which showed that the small concentrations of both treatments. It was close to ward in an increase in plant height. 5. Number of branches also significantly decreased when ornamental plants treated with dry or fresh Eucalyptus leaves; the Calendula officinalis plant was the most affected. 6. For the changes in ornamental plants height, as a result of treatment with dry or fresh leaves of Eucalyptus, during life time - course, it was clear the growth curve was close to the S - shape growth curve with obvious significant differences for most treatments compare to control. 7. Dry weight percent was significantly affected in all ornamental plants when they treated with dry or fresh Eucalyptus leaves, If decreased with the concentration of the treatments increased. 8. It was obvious that treatment with dry or fresh Eucalyptus leaves resulted in significant reduction in flower number and flower diameter. Number of flowers decreased as the concentration of the treatments increased. on the other hand, flower was diameter increased as the concentration of the treatments increased, but in both cases it was less than the control. All one obvious that reducing significant in flower diameter, It was reducing great in low levels. 9. Chlorophyll content was also decreased in leaves, while anthocyanin content in petals was increased when the ornamental plants treated with dry or fresh Eucalyptus leaves. 10. Nirogen percent, phosphorus and potassium content in leaves of the four ornamentals decreased when they treated with dry or fresh Eucalyptus leaves. 11. Using terpenes, alkaloids and phenols caused significant increase in sugar content in leaves of the ornamentals, reaching its highest values at the highest concentration of the terpenes. For protein content, it was gradually decreased as the terpens, alkaloids and phenols concentrations increased in Calendula officinalis. In Tagetes patula, protein content was noticeably increased with the increasing in concentrations of the treatments. 12. Malondialdehyde, glutathione and proline content increased significantly in Calendula officinalis and Tagetes patula plants when they treated with terpenes, alkaloids or phenols. 13. Interaction between treatments concentrations and kind of plants had significant effect on all parameters measured.

Abstract: “The current research dealed with fourteen taxa belonging to the genus Ranunculus L., Family Ranunculaceae that grown in Iraq. The study included the gross general morphological and micromorphological characters, the Pollen grains also were studied and the chemical compounds (Flavonoids), Ecological and geographical distribution and taxonomic treatment have been done. Also botanical key was puted to separate the Taxa”.“General survey for the Phytogeographical districts where the taxa spread in, and the result was a large crowds of samples, and new locations of taxa distribution were recorded. The specimens in the Iraqi herbaria were studied after ensuring that it was correctly identified”. “Comparative morphological study was undertaken to all plants parts of taxa including the roots, leaves, stipules, flowering parts and fruiting parts. Charts, diagrams, tables were drawn and accompanying with natural images for different morphological characteristics, as well as the field images that are important for the study. This study showed that all the taxa of the genus were herbs that are annual or perennial. There was agreat important for the roots, stems and there Indumentum, the presence orabsence of stipules, shape and size and margin of basal leaves and cauline leaves and leafy bract, the shape of sepals and their numbers and their Indumentum, the numbers and shape of Petals and their colors, the number of Stamens and the colors of Anthers, the shape of ovary and their indumentum, presence or absence of style as it was very useful for the taxonomic identification and separation of the studied taxa. As well as the fruiting parts including the length of fruiting peduncle, the fruiting receptacle, the fruiting head and its shapes and their dimensions, the number of Achene Fruitlets and their sizes, colors and Beak shape. Also the surface configuration of the fruitlets Surface has been studied by (SEM) as it wae either hairy or tuberculate - hairy or Transversely rugose or muricate or reticulate or reticulate - minutly rugose or granular or granular - hairy or granular - hairy tuberculate or spinulose”.“The study of the micro - morphological characters of hairs, leaves epidermal cells and the stomatal complex, have a taxonomic importance of supporting the morphological characters in separation and identification of the genus taxa”.“The study show that the pollen grains have a taxonomic importance because of their difference in shape, dimensions, the wall thickness and their ornamentation. It was either apolar which was spheroidal and pantoporate, or isopolar which has different shapes in the equatorial view it was spheroidal, subprolate and oblate - spheroidal, it was either 3 - colpate, 4 - colpate or 5 - colpat.the colpate where either zonocolpate or syncolpate in the form of parasyncolpate. The ornamentation were verucate, echinateand scabrate”. “The chemical study also has an importance in separation of the genus taxa, six flavonoid compounds were diagnosed by using” HPLC wich are Kaempferol, Vitexin, Orientin, Quercetin, Iso - vitexin and Iso - orientin. According to the presence or absence of those structures cluster analysis where done for the results of the flavonoid compounds and the taxa where divided into groups that reveal the chemical relationships between them.dendogram where performed which also show the chemical relationships between the taxa by using UPGMA method and NTSYS program issue 21. the study shows that the presence and distribution of those compounds vary according to the variation in the plant distribution the study shows that some of the taxa have “the same compounds which enhance its belonging to the Ranunculus genus”. “Through field surveys and information installed on the herbarium samples, the taxa where distributed on their growth areas, and maps have been drawn for taxa distribution in the Iraqi natural geographical. Most of the taxa were distributed in N. and N.E of Iraq regions districts especially in MAM, MSU, MRO, and FBF districts. We notice that MSU district has a great number of the plants under the study as we found there are all the taxa accept one”. This study helps to detect distribution areas for some taxa that have been not mentioned in the Iraqi flora or other records which are R.kotschyi and R.trichophyllus var.trichophyllus. Also the study records distribution for the new species R.chius in MAM district which hasn't been mentioned in the Iraqi flora in this district before. Finally all the taxa were classified and the botanical key was done to separate them.
