المستخلص: Present study was conducted in the Plant Tissue Culture Laboratory, Agriculture Collage, Basrah University, Basrah , Iraq, in the period 2012 - 2014. The objective of this study was to evaluate the effect of different concentrations of growth retardant (paclobutrazol) and casein hydrolysate on somatic embryogenesis formation and germination in date palm (Phoenix dactylifera L.) cultured in vitro. The shoot tip explants were excised from offshoots that approximately 3 - 4 years old. Shoot tip explants then cut it in four segments and each segment cultured on Murashige and Skoog (MS) basal medium containing different concentrations of paclobutrazoal (0, 0.3, 0.5, 0.7, 0.9 and 1.0 mg/L) or casein hydrolysate (0, 200, 400, 600, 800 and 1000 mg/L).Results obtained in this study can be summarized to : 1 - Study showed that the MS medium containing pacloputrazol (1.0 mg/L) or casein hydrolysate (1000 mg/L) increased in fresh and dry weight of primary callus and embryogenic callus comparing to control treatment.2 - Primary and embryogenic callus cultured on MS medium fortified with 1.0 mg/L paclobutrazol for a long period showed superiority in fresh and dry weight compared with other treatments and control.3 - The period need it for somatic embryo formation was decreased to (17 and 20.33 days) when the embryogenic callus with 0.5 and 0.7 mg/L of paclobutrazol respectively. Results also revealed that the numbers of white and big spherical somatic embryos were appeared when high concentrations of paclobutrazol 1mg/L and casein hydrolysate (1000 mg/L) have been used.4 - The rate of somatic embryos length were increased when the concentration of casein hydrolysate increased to 1000 mg/L. In contrast, length rate of somatic embryos were decreased when treated with paclobutrazol.5 - High fresh and dry weight of somatic embryo were recorded on MS medium containing (0.9 and 1 mg/L) of paclobutrazol.6 - The high germination rate of somatic embryos was obtained on MS medium containing 0.3 and 0.5 mg/L paclobutrazol or MS medium enriched with 800 and 1000 mg/L in short time in comparing with other treatments.7 - Among the different concentrations of paclobutrazol tested, 0.3 and 0.5 mg/L were the most effective concentrations for increase the length of leaf and primary roots, but the 0.7mg/L and 0.9 led to increase root numbers only, whereas the high concentration of paclobutrazol 1.0mg/L increased the length of leaf and decreased the rate of roots. In contrast the high concentrations of casein hydrolysate (800 and 1000 mg/L) affected positively on leaf and root length.8 - Embryogenic callus tissue subjected to 1.0 mg/L paclobutrazol, containing high carbohydrate, whereas, embryogenic callus treated with 0.5 and 0.7 of paclobutrazol containing high protein. In contrast, embryogenic callus tissue treated with different concentrations of casein hydrolysate containing high carbohydrate and protein.9 - Histological study revealed that the high concentration of paclobutrazol reduced the size of cells in compare with control treatment.

Work involving comparative morphology, anatomy, palynology, ecology & geographical distribution and numerical taxonomy has been presented. The morphological study includes studying the characters of root, stems, leaves, inflorescences, phyllaries, flowers, and fruits in addition to indumentums. It has been clear that the characters of stems, leaves, involucres bracts and fruits have a taxonomic importance.Also it has studied some of the micro morphological characters and their taxonomic importances were assessed.The present study showed that the pollen grains of all species were found to be tricolporate with echinate surface & of little taxonomic value. This study also includes characters of the epidermal leaf and stems, indumentums, venation and transverse section of stems and leaves discussion were also included, the taxonomic importance of each character & its variation, it is shown that these characters have an importance assessing morphological characters to isolate these species.Data obtained from herbarium specimens, literature and trips was utilized to elucidate the ecology of the species. Maps of geographical distribution were prepared for all species studied. It has been shown that R.angulosus was the most widely distributed species in the country. The species under current study were numerically treated ; dendrograms and polygonal graphs were drawn for the species of the genus. In conclusion (4) species of the genus Rhagadiolus : R.angulosus, R.edulis, R.hamosus and R.stellatus were recognized for Iraq, taxonomic treatment has been carried out for all Rhagadiolus species and key was designed for them too.

المستخلص: 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.

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.

المستخلص: يتعرض الحليب للعديد من الملوثات الفيزيائية والكيميائية والبيولوجية وذلك بسبب طرق الانتاج واسلوب النقل وعمليات التسويق ومن هذه الملوثات المعادن الثقيلة والرقم الهيدروجيني ودرجة الحرارة والبكتيريا. وقد صممت الدراسة الحالية لفحص عينات للحليب الخام التي جمعت | Milk is subjected to various physical, chemical and biological pollutants duo to producing, transporting and marketing processes such as certain heavy metals, pH, temperature and bacteria. The current study was designed to examine fresh milk samples were collected randomelly at early morning from six different locations at a rate of once each month during study period which commenced in October 2013 and ended in march 2014 and powder milk brands which were examined again for six months as in case of fresh milk where these milk brands were collected from local markets each month. The results of heavy metals showed that : • The investigation of Lead content in raw milk revealed that the highest mean value (1.801±0.311 ppm) was scored in Abo - Ghraib sample and the lowest mean value (0.941±0.104 ppm) was observed in Ghazaliya sample. For the Cadmium content in raw milk that the highest mean value (1.532±0.124 ppm) was found in Abo - Ghraib sample and the lowest mean value (0.063±0.044 ppm) was found in Fal'loga. The Copper content in raw milk also investigated and resulted the highest mean value was (0.931±0.092 ppm) in Azizia milk sample and almost similar value (0.931±0.301 ppm) was found in Madain sample while the lowest mean value was (0.308±0.029 ppm) in Fal'loiga sample. The highest mean value of Potassium in raw milk was recorded in two samples in Azizia (9718.8±246.6 ppm) and (9718.3±482.2 ppm) in Abo - Ghraib but the lowest mean value (4156.3±268.3 ppm) was recorded in Essaouira. Regarding Sodium content in raw milk, the results have found that the highest mean value was (2968.8±312.2 ppm) in Essaouira sample while the lowest mean value was (1432.5±156.8 ppm) in Abo - Ghraib. The Chloride content in raw milk samples, the highest mean value was (3053.0±128.6 ppm) recorded in Fal'loga sample and the lowest mean value was (639.0±198.4 ppm) was found in Azizia sample. Analysis of variance of these data showed significant effects (P?0.001) of both sampling sites and collecting months on milk (pb, Cd, K, Na and Cl) contents while analysis of variance of these data reveals no significant impact of sites on milk Cu content (P> 0.05) where no differences were observed between mean value of different collecting sites but shows highly significant (P? 0.001) effects of collecting months.• While powder milk has shown that the highest mean values of Lead (1.225±0.052 ppm) were found in Al - Mudhish brand and the lowest mean value (0.088±0.002 ppm) was detected in Anchor. The highest mean Cd value was (0.184±0.005 ppm) in Nido brand and the lowest mean value was (0.069±0.003 ppm) in Altunsa sample. While the highest mean value of Copper was (1.656±0.254 ppm) in Dielac powder brand and Anchor milk brand had the lowest copper mean value which was (0.767±0.014 ppm). The concentration of Potassium was (9625.0±462.9 ppm) which is the highest recorded in Dielac milk sample and the lowest mean value (3356.8±225.6 ppm) was found in Al - Marai milk sample. While the highest average of Sodium was (2625.0±342.6 ppm) scord in Dielac brand and the lowest average was (1745.0±338.4 ppm) recorded in Al - Marai sample. The highest mean value of Chloride (193.0±41.0 ppm) was recorded in Nido milk brand and the lowest mean value (122.7±22.2 ppm) was found in Altunsa milk sample. However, analysis of variance shows significant differences (P?0.001) between examined milk brands while no such differences were found between these brands (P>0.05) regarding collecting months.From the above results, it seems that the highest content of (Pb, Cd and Cu) are higher than those of standards of the International Dairy Federation (IDF) while contents of (K, Na and Cl) are within the standard requirement according to National Research Council (NRC).Microbial tests of raw milk samples were positive for bacterial growth, as different bacterial species were observed such as Lactobacilli spp. 63.8%, Streptococcus spp. 61.1%, Staphylococcus aureus 44.4%, Escheritia coli 88.8%, Bacillus spp. 72.2%, Salmonella typhi 72.2%, Staphylococcus epidermidis 30.5%, Pseudomonas spp. 47.2%, Micrococcus spp 27.7%, Clostiridia spp. 66.6%, Enterococci spp. 11.1% and K. pneumonia 75% from bacterial contamination of raw milk samples.However, only (11.1%) of the total collected samples of raw milk were suitable for human consumption and (88.9%) unsuitable, indicating that the source of infection or contamination of milk may be due to the animal health, human handler and the environmental factors, e.g., contaminated vessels, polluted water, flies and dust, etc… Obviously, bacterial contamination test of powder milk samples was carried out and negative results were obtained. However, it seems clearly that the opportunity of finding bacterial contamination in powder milk samples may be very rare since milk powder is produced in well designed and modern techniques. Nevertheless, a single bacterial contamination test has indicated to a positive growth of Staphylococcus aureus colonies.

Lippia nodiflora (L.) Rich.29. Tribulus terrestris L.Some of these species have been anatomically investigated for the first time.Anatomical characters might be useful for plant biologist for the identification of important wild plants as an additional character at global level. Comparative anatomical characters were used; such as characteristics of ordinary epidermal cells of stems and leaves and stomatal complexes. The epidermis possesses number of important diagnostic character that offer valuable clues for identification, like size, shape, in addition to indumentum of both stems and leaves. Venation system was investigated and compared. Cross sections of root were useful taxonomically especially the thickness of epidermis, cortex, phloem and xylem. The study observed presence of sclerenchyma tissues in the root cortex of some species. Cross sectioning of stems and petioles were also studied. Epidermis, cortex, pericycle, vascular bundle shapes and numbers, pith characters, presence of crystals and tannin filled cells were useful aid in distinguishing species. Vertical sections of leaf blades, shape and number of vascular bundles, thickness of palisade and spongy layers and other mesophyll characters were important taxonomically.ccording to some of these characters, species were divided into groups. This study concluded the presence of variations in characters and these were presented for the first time comparatively, so that, the anatomical characters were a good support to the exomorphological characters in the studied species. Field photographs of the different studied plants and sections of organs were put in addition to numerous tables in this work. The above results were discussed scientifically regarding mainly the environmental factors.

المستخلص: تضمنت الدراسة الحالية عزل وتشخيص طحالب كبيرة من بيئتين مائيتين محليتين مختلفتين. تم عزل ثلاث طحالب كبيرة هي Cladophora glomerata (N) وEnteromorpha rafsii من منطقه بحر النجف في محافظة النجف, في حين عزل Cladophora glomerata (R) من احد مبازل منطقة الراشدية ش | The present study includes isolation and identification of Macro - algae from two different environmental water bodies. Three Macro - algae were isolated, Cladophora glomerata (N) and Enteromorpha ralfsii from Baher Al - Najaf region in Holy Najaf city. In addition, C. glomerata (R) was isolated from Al - Rashdiya, north of Baghdad.Phytopathogenic fungi from soil and some infected fruits were also isolated. They were identified as Pythium ultimum and Rhizoctonia solani.Water and ethanol were used to extract each algae to evaluate their antifungal activity against isolated phytopathogenic fungi. Different concentrations of these algal extracts had been prepared which are (10, 25 and 50) mg/ml and the antagonistic activity against the isolated phytopathogenic fungi were evaluated, the hot and cold water extracts did not show any antagonistic activity against fungi. However, all these extracts were ignored in the future work for this study. Furthermore, the hot ethanolic extract was more efficient than these of cold ethanolic extracts. Results have been shown that there were significant differences when macro - algal ethanolic extract were used.C. glomerata (R), which isolated from Al - Rashdiya, was more efficient against tested fungi than the same alga what isolated from Baher Al - Najaf region. However, E. ralfsii extract was more efficient against tested fungi than C. glomerata (N). Percentage of inhibition against P. ultimum when hot ethanolic extract of E. ralfsii, C. glomerata(R) and C. glomerata(N) were (88.8, 83.3 and 63.3) respectively.However, results for cold ethanolic extract of the same algae were (63.3, 52.2 and 32.2) respectively when 50 mg/ml of algal extracts were used.Percentage of inhibition against R. solani when hot ethanolic extract of E. ralfsii, C.glomerata (R) and C.glomerata(N) were (94.4, 100 and 78.8) respectively.However, results for cold ethanolic extract of the same algae were (66.6, 64.4 and 48.8) respectively when 50 mg/ml was used. According to the difference in biological activities against those phytopathogenic fungi caused by the same species of macro - algae or different genera from different environments. Due to difference in biological activity of the same macro - algae species Physiochemical parameter for each environments obtained such as air and water temperature, Turbidity (NTU), Electrical Conductivity(EC)and Salinity%, Water pH, CA+2 concentration, Mg+2 concentration, Total Hardness and Total Alkalinity. Results indicated that soaked Cucumis sativus and Capsicum annum seeds in cold and hot ethanolic macro - algae extracts of (E. ralfsii, C. glomerata (R) and C.glomerata (N) for 24 hours were able to protect seed germination that have been grown in a Petri dish contaminated with P. ultimum and R. solani comparing with control. In addition, results indicated that spraying C. sativus and C. annum seedling with these algal extracts within two weeks old again protects these seedlings from the same phytopathogenic fungi either before or after 24 hr. However, results indicated that adding the algal extracts within two months age to the C. sativus and C. annum plants again protects these plants from the same phytopathogenic fungi comparing with control and fungicide treatment. Moreover, results indicated that the active chemical compounds in E. ralfsii was Tannins, Saponins and Flavonoids. While C. glomerata was contained Tannins, Saponins, Alkaloid and Phenols. Results indicated that both hot crud methanolic extract of C. glomerata (R) and E. ralfsii have a lot of active chemical compounds against micro - organisms by using the GC - Mass Spectrometry technology.
