Abstract :

Salicylic acid has significant role in the different stages of plant development ( phenology ). This molecular messenger plays an active role in the plant's defensive response. To elaborate this, studying morpho-physiologic and biochemical, salicylic acid priming ( SA ) impacts in 6 levels ( 500, 750, 1000, 1250, 1500, and 1750 micromullar per litre )together with hydro-priming and control on the hemp seeds in the complete random blocks in 4 replications in the laboratory and greenhouse setting was designed and carried out. The results indicated the meaningful impact of the priming seeds of the hemp, with SA and distilled water on the antioxidant ( CAT, POD ), the significant indexes of germination ( P<0.05 ), and biologic yield of ( P<0.05 ). With the increase of the levels SA, biological yield had ascending process, and in the highest SA level, it showed 43 percent increase in relation to control. Therefore the usage of external SA increased the germination, better establishment of plantlet and improvement of significant indexes in plant physiology specifically in the primary stages of growth which had influence on the biological yield of the plant.
