Abstract:
اشتملت هذه الدراسة على ثلاث تجارب اثنتان منها مختبرية والثالثة حقلية وباهداف مختلفة على نبات زهرة الشمس. Helianthus annuus L. التجربة المختبرية الاولى نفذت بتاريخ 21/4/2013 ولغاية 1/5/2013 لمعرفة تاثير دقائق الفضة النانوية بتركيزين هما (, 2550) سم3. لتر | The study included three experiments, two laboratory and the third field experiment with different goals on sunflower (Helianthus annuus L.) the Spanish cv. 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.
