المستخلص: This study was conducted at the tissue culture laboratory at the Dept. of biology, College of Education pure Sciences from 1/3/2012 - 1/12/2014.With the objective of studing the tolerance of the salt stress of two rice (Oryza sativa L.)cultivars namely Anber and Furat using the technology of tissue culture. . Mature seeds (mature embryo and endosperm) were used as bing parts of explants which were cultivated in a semi - sold( Murashige and Skoog 1962) nutrient medium and some additives such as vitamins and amino acids .The growth regulator Dichlorophenoxy acetic acid (2.4 - D)was used, about 8mg/l , sucrose at 30g.l - 1 . . The study ,also ,tested the effect maltose at 30g.l - 1, and the effect of 0.5g/l of casein hydrolest were tested.the study also included the different of sea water concentrations (0,20,40,60)%on the induction of growth and development of callus ,the effect of green algae extract at Cladophora crispate by adding 1g fresh weight to the nutrient medium with all sea water concentrations.All the features of the callus were tested as well as the effect of the interaction between sea water concentrations and algae extract , as well as interactions among rice cultivar x sea water concentration x algal extract.The study depended on some growth indicators to determine the degree of callus to tolerance towards salt stress .the resistance of callus to salt depended on regeneration through the required of time for the formation of embryos ,number of germinated embryos ,and number of plantlets .The concentration of the major metal ion : sodium, potassium, phosphorus, calcium ,magnesium, potassium/sodium percentage , and the minor metal ions : iron ,copper, manganese were also some chemical components such as protines and amino acid proline measured, were also measured .The randomized block design (C.R.D)and factorial experiments were used depending ten replicates per treatment .The results can be summarized as follows : 1 - The results showed that the addition of sugar di maltose as an energy source and Casein hydrolyses to the nutrient medium had appositive effect on significant decrease in the required time to mitiate the callus ,in the increase of callus induction percentage and in the increase of freshweight of initial callus. .2 - The effect of sea water and algae extract : . A - The current study shaued that the addidtion of 20 and 40 % sea water to the nutrient medium resulted in a significant increase in the required time to induce the callus ,and a significant decrease in the percentage of callus induction and weight of the mitial callus as compared with the control treatment .The concentration 60%0f sea water caused the mature seeds to lose their ability to germinate and induce the callus if no induction occurs at all . The effect of algae extract resulted in a significant decrease in the required time for callus induction ,and a significant increase in the percentage of callus induction ,the weight of the mitial callus and 0,20,40% of sea water as compared with free algae extract medium.B - The results showed that the addition of 20% of sea water to the nutrient medium that is prepared for the growth of the embryo callus led to a significant increase in the fresh weight as compared with the control treatment , whereas the two concentrations 40 and 60%sea water led to a significant decrease in the embryo callus weight .The effect of the algae extracted to a significant increase in the fresh weight of the embryo callus with sea water concentrations as compared with the free algae extract medium.C - The addition of 20,40 and 60%sea water cause a significant decrease in the number of the somatic embryos ,thir germination auerage ,number and germination of the formed plantlets . This addition also caused a significant increase in the required time to stare the germination of the somatic embryos as compared with the control treatment .The addition of the algae extract led to increase the number of formed embryos ,germination percentage ,and number and percentage of plantlets ,wher was the addition led to lower the required time to germination the embryos compared with the free algae extract medium.D - The addition of 20 ,40 and 60% sea water to the nutrient medium resulted in a significant increase in the concentration of sodium ,calcium ,and magnesium ion in the embryo callus ,while a significant decrease occurred in the concentration of potassium and phosphorus ion and thedpotassium/sodium percentage as compared with the control treatment .The abone mentioned concentrations 0f sea water led to significant increase in concentration of ion ,copper, and zinc ions ,and significant decrease in manganese ion ,The addition of the algae extract caused in lowering the concentration of sodium ion .This decrease was significant in the 60 % sea water medium. The ingrease of potassium ,calcium ,phosphorus, and magnesium ion in embryo callus tissue when compared with free algae extract medium and was significant with some sea water concentration.E - The results ,also ,showed that the addition on 20, 40 and 60% concentrations0f sea water resoled in a significant decrease in concentration of some chemical ingredients such as protein and amino acid proline of the embryo callus in comparison with the control treatment . as far as the effect of the algae extract is concerned ,the addition of this extract to the nutrient medium led to a significant increase in the concentration of the proteins and amino acid prolne as well as with all sea water concentrations.F - The results of study showed that the addition of 20,40,60% sea water led to a significant increase in the rate 0f effectiveness 0f the enzyme Super oxide dismutase (S.O.D) and enzyme Ascorbate peroxides (APX),reaching the highest rate of effectiveness of the enzyme at the concentration 0f 60% compared with the comparative treatment , whil the highest average of the effectiveness of enzyme Catalase (CAT)and glutathione piroxidase (GP)and polyphenoloxidase (ppo)was at the concentration 20%sea water then it started to decline when increasing the concentration of sea water from 40 to 60% As for the algae extract it has been shown from the results of the current study that the addition of algae extract to nutrient medium to a high effectiveness of enzyme SOD,CAT ,APX and GP and more significant with all concentration of sea water The impact of algae extract on the effectiveness of the enzyme PPO has led to increasing the effectiveness of this enzyme but did not amount to a significant level except with sea water nutrient medium .G - The results of the current study showed a significant increase of the Amber cutivar in the percentage of the callus induction and the required time of this induction as well as the Wight of the initial and embryo callus ,number and germination percentage of thesomatic embryo , number of plantlets ,as wall as the percentage of the accumulation of potassium ,phosphorus ,calcium, and manganese ions ,as will as in the potassium/sodim ratio focus histidine proline and the effectiveness of the enzyme SOD and CAT enzyme and enzyme GP. While the product was higher than in the accumulation of Firat magnesium ion ,zinc copper and in the effectiveness of the enzyme in APX & PPO . .

The aim of the study was studying response of two okra varieties (Al - Husenawyia and Al - Pteira) humic acid and zolfast application methods (foliar and addition to irrigation water) and this concentration (recommended and doubled) on growth and productivity as well as leaf mineral and fruit medicinal active constituents.The humic acid and zolfast formulas were added by the use of hand sprayer or with irrigation water with the recommended and doubled concentrations for humic acid and zolfast as foliar spraying were 1 ml.L - 1 and 2 ml.L - 1 if doubled respectively while when used with irrigation water 4.8 ml.L - 1 and 9.6 ml.L - 1 if double for humic acid 7.2 and 14.4 ml.L - 1 for zolfast if doubled.The design of the experiment was Randomized complete blocks in a factorial arrangement (2×2×5) in three replications. The RLSD at 0.05 was used as a method to compare means separation treatment effect was evident. The results showed : 1 - Al - Husenawyia variety was superior in total leaf area, vegetative fresh and dry weights, root fresh and dry weights, P% and content addition to specific leaf weight, relative growth rate, fruit length, number of fruit/plant, fruits yield compared to Al - Pteira. Percentage of protein, carbohydrates, total soluble solids, caprylic, lauric saturated fatty acids and all the unsaturated fatty acids. Mucilage, folic acid and oil refractive index were also higher with Al - Husenawyia compared to Al - Pteira had higher stem diameter, fruit fresh and dry weight, K%, boron content and percentage of saturated fatty acids (Myristic, Palmatic, Stearic, Arachidic and Behinic). Ca% was the same for both cultivars.2 - Foliar application method of humic acid and zolfast showed beneficial effect on and all parameters studies except root fresh and dry weight and percentage of saturated fatty acids increased with irrigation water (except Lauric acid which was increased with foliar application). Methods of application did not affect stem diameter, Ca% in leaves and fruit total soluble solids.3 - Although the double recommended concentrations of humic acid and Zolfast reduced saturated fatty acids significantly their recommended concentration lowered saturated fatty acids (Caprylic, Myristic, Palmatic, Stearic, Arachidic and Behinic) compared to control treatment. Percentage of fiber was lower with the use of zolfast compared to humic acid and control. While K% was lowered when zolfast used in the double recommended concentration. No significant difference were found between the recommended concentrations of humic acid or zolfast in stem diameter, total leaf area, relative growth rate, vegetative dry weight, root dry weight, P%, Ca%, boron content, fruit length, number of fruit/ plant, fruit dry weight, mucilage, carbohydrates%, folic acid, oil%, percentage of saturated fatty acids (Caprylic, Myristic, Palmatic and Arachidic) and unsaturated fatty acids (Oleic and Linoleic) and the percentage of unsaturated fatty acids/saturated.4 - The interaction between cultivars and methods of application revealed that foliar application of both humic acid and zolfast reduced saturated fatty acid (Caprylic, Myristic, Palmatic, Stearic and Arachidic) significantly of both cultivars, compared to their addition to irrigation.5 - The interaction between cultivars and substances of application (humic acid and zolfast concentrations revealed that both cultivars had different response in some traits of studied to applied concentrations of humic and zolfast. Al - Husenawyia variety had higher vegetative fresh weight, root dry weight and fruit of mucilage content with the double recommended humic acid. While Al - Pteira variety had higher TSS% and Lauric acid% when used the double recommended concentration of zolfast.6 - The interaction between methods of application and concentrations of application substances showed superior effect on some studied parameters. Foliar application method was superior on addition to irrigation application with all concentrations except root fresh and dry weight and saturated fatty acids% (except Lauric acid) which were increased when added to the irrigation water to all concentrations of application substances. The same interaction did not revealed significant difference in stem diameter, Ca% and fruit fresh and dry weight.7 - The three way interaction factors studied in the experiment revealed an increase in growth parameter of both cultivars when humic acid and zolfast were added in their higher concentration (double recommended) by foliar application expect root fresh and dry weight and saturated fatty acids% (except Lauric acid) which were increased when added to the irrigation water. Al - Husenawyia variety was higher in all parameters with the use of higher concentration of humic acid and zolfast when applied with irrigation water or foliar application. The three way interaction revealed no significant difference in stem diameter, vegetative dry weight, Ca%, fruit fresh and dry weight, TSS%, percentage of oil and unsaturated fatty acids (Linoleic and Myristoleic).8 - Results of electrophoresis analysis revealed that the use of the doubled recommended concentration of humic acid and zolfast with irrigation water participated in building higher protein molecules in fruits to both cultivars. While the double recommended concentration of humic acid and zolfast did not show this trait when foliar applied.

Viki. The first laboratory experiment was performed from the period 21/4/2013 until 1/5/2013 to determin the effect of two nano silver concentrations 25 and 50 cm3/L and two concentrations organic fertilizer (Algastar) 0.75 and 1.5 g/L and two concentrations of salicylic acid 30 and 60 mg/L on seed and speed of germination of sunflower seeds by soaking the seed with above mentioned concentrations seperatly in addition to the control treatment which was soaked with distilled water only. The second laboratory experiment was perfomed from the period of 28/10/2013 until 4/12/2013. In this experiment sunflower seeds was soaked in 25, 50 cm3/ L nanosilver and 30, 60 mg/L of salicylic acid and the resulted plants were sprayed by 0.75, 1.5 g/L (Algastar) in addition to the control treatment during the third leaf stage to determine its impact on growth and shoot content of DNA, RNA and leaves content of oxidizing enzyme peroxidase and catalyase. The field experiment was carried out from the period of the agriculture 5/3/2013 until 18/6/2013 sixty five day after sowing the seeds the resulted plant shoots were sprayed with 25, 50 cm3/L of nanosilver, 0.75, 1.5 g/L of Algastar and salicylic acid 60, 120 mg/L in addition to the control treatment. The design of the first laboratory experiment was completely randomized design CRD with seven treatment and seven replication.The design of the second laboratory experiment was CRD with fifteen treatment combination and seven replications. The experiment design for the field experiment was rendomized complete randomized block design RCBD in factorial arrangement (3×3×3×3). The least significant difference LSD at 0.05% level was utilized for mean comparison, whenever treatment effect was evidents of Lab experiments. Resulted showed : - 1 - The use of silver nanoparticles, organic fertilizer (Algastar) and salicylic acid no effect neither on seed germination and nor to speed germination.2 - Results of the second laboratory experiment revealed that shoot content of of DNA, RNA was higher in plants resulted from soaking seeds with nanosilver and salicylic acid when sprayed by 1.5 g/L Algastar that with 0.75 g/L at the third leaf stages and leaves content of oxidative enzymes peroxidase, catalyase was higher when shoot were sprayed by 1.5 g/L organic fertilizer.The organic fertilizer Algastar in 1.5 g/L showed higher effect on all parameter studied in this experiment than 0.75 g/L. 3 - Treatment concentration of 50 cm3/L nanosilver and 1.5 g/L Algastar showed higher effect on plant height, number of root branches, fresh weight of shoot and root, leaf chlorophyll content as well as potassium, DNA, RNA and catalase enzyme.Results of the field experiment revealed 1 - The use of nano silver in 50 cm3/L /L had appositive effect on most vegetative parameters studied except stem diameter which was reduced at this concentrations.leaf content of auxins, seed content of DNA and RNA, phenols as well as protein, unsaturated fatty acid were also higher when 50 cm3/L of nanosilver was used while vicine content of the seed reduced. 2 - The use of organic fertilizer Algastar in 1.5 g/L improved most vegetative, flowering and the chemical constituents of seeds.But reduced stem diameter, seed content of vicine and saturated fatty acid 3 - Salicylic acid 120mg/L improved vegetative parameters and reduced stem diameter, seed content of vicine and saturated fatty acid (plmatic, stearic, archedic) and had no effect on specific leaf weight or seed content of saturated fatty acid myristic.4 - The interaction between of nanosilver and organic fertilizer revealed that concentrations of 50 cm3/L of nanosilver and 1.5 g/L of organic fertilizer improved vegetative and flowering parameters.Auxin content of the leaves, seed content of protein, phenoils, oil percentage and unsaturated fatty acid linoleic and oleic was higher at this treatment, But reduced vicine in seeds, and saturated fatty acids palmitic, stearic and had no effect on phosphours content of seeds and ? - linolenic.5 - The treatment concentration of 50 cm3/L nano silver and 120mg/L salicylic acid gave highest plant height, chorophyll content, auxins and seed content of phosphours, proteins and RNA while seeds saturated fatty acid (palmitic and stearic) were reduced to the a bove mentioned treatment concentration.6 - Treatment concentration of organic fertilizer and salicylic acid had fluctuate effect on parameter studied upon their concentrations.1.5 g/L of organic fertilizer and 120 mg/L salicylic acid increased protein, RNA, and linoleic acids of the seeds.Also 0.75 g/L of organic fertilizer and 120 mg/L salicylic acid increased ? - linolenic, but other treatment combination showed no effects on most parameters studied.7 - The three way interaction between nanosilver, organic fertilizer and salicylic acid reduced stem diameter and had no effect on leaf area, specific leaf weight, potassium, auxins, and seed content of vicine and seed oil percentage and oil production and fatty acids (palmitic, stearic, archedic, myristic, linoleic, oleic acid), but increased ? - linolenic.

The goal was assess the effect of water stress, foliar application of proline and their interactions on characteristics morphological, physiological and nutritional status of three genotypes of maize namely : Serour, 5018, and Baghdad - 3.The characteristics included root's volume, root's length, root's diameter, root's dry weight, plant height, leaves number, leaf area, shoot dry weight, root/shoot ratio, absolute and relative growth rates and content of chlorophyll and proline in the leaves. The nutritional status included, the concentration, the contents and the rates of absorption and transport of N, P, K, Ca and Mg.In addition to the molecular study which included the technique of Random Amplified Polymorphic DNA (RAPD) DNA. A Factional experiment within Completely Randomized Design (C.R.D.) was adopted i.e. three genotypes of maize namely : Serour, 5018, and Baghdad - 3, proline (0, 50, 100 and 150) mg. L - 1 and two levels of field capacity (50 and 100) % with three replicates in a total of 72 experimental units.Means were compared using the least significant difference (LSD) at 0.05 probability level. Results could be summarized as follow : 1 - Genotypes significantly differed in the studied traits.The cultivar 5018 gave the highest values of root's volume, root's length, root's diameter, root's dry weight, plant height, and root/shoot ratio for spring and fall cultivations.The same cultivar gave higher values of P%, Ca%, Mg% in roots and the content of N, P, K, Ca and Mg in roots, rates of absorption and transport of N, P and Ca in spring and fall cultivations.Leaves P%, Ca% and Mg %, leaves Mg content and absorption and transport of Mg in fall cultivation. on the other hand, Serour cultivar give higher values of leaves number, leaf area, shoot dry weight, absolute and relative growth rates, content of chlorophyll and N% in root in spring and fall cultivation. P% in leaves in fall cultivation, leaves K% in both cultivation, content of N, P, K and Ca of shoot in both cultivations, shoot's Mg content of shoot in fall cultivation, content of N, P, K and Ca of shoot in both cultivation and Mg content of shoot in fall cultivations. Baghdad - 3 cultivar give higher values of proline content, Mg% in roots in both cultivations, shoot Mg% in fall cultivations, absorption and transport rates of K in fall cultivation, transport rate of Ca in spring and fall cultivations and absorption and transport rates of Mg in fall cultivation. 2 - Apart from Ca% of root in spring and fall cultivation, the proline markedly influenced all the rest traits where 100 mg. L - 1 proline gave the highest values compared to control treatment (i.e. 0 proline) that gave the lowest values. The proline at 50 and 150 mg. L - 1 gave intermediate values for all studied traits. 3 - Apart from some cases, 100% field capacity treatment gave higher values of most studied parameters. The field capacity of 50% gave higher values of N% and K% in roots and leaves, the content of N and K of roots and shoots and rates of absorption and transport rates of K in spring and fall cultivations. on the other hand, there was no effect of field capacity on Ca% of roots and shoots in spring and fall cultivation and Mg% of roots in spring cultivations. 4 - Bi and Tri interactions effect was profound on most studied characteristics. 5 - Through molecular study that including isolation of DNA in leaves of maize , a quantity of DNA ranging between 150 - 290 nano - gram / ?l with 1.8 - 1.9 purity was obtained. The differentiation of (RAPD) DNA was analyzed in order to prepare the finger print of maize genotypes. Six primers were tested (OPA - 09, OPA - 11, OPA - 13, OPC - 12, OPD - 20 and OPN - 16). The primers revealed different multiplication products between genotypes.The least value of genetic distance was 0.4103 between 5018 and Baghdad - 3genotypes, while the highest value of genetic distance was 0.7932 between Serour and 5018 genotypes.Data analysis revealed that these genotypes are divided into two main groups namely : group included 5018 and Baghdad - 3 genotypes, and group included Serour genotype only.
