Changes In Biomass Gain, Protein Content And Hormonal Levels In Wheat Kernels In Response To Soil Drench With Sodium Salicylate

Abstract

Drenching of soil with sodim salycylate (800,4000 and 8000mg/l) increased grain f. wt. and d. wt. Protein content was increased in grains at days 23 and 60 with 800 mg/1 salicylate. With higher doses "4000 and 8000mg/l protein increased during grain filling. Sodium salicylate increased significantly the ABA content in grains compared to control. A significant decrease in auxins and gibberellins in grains was noticed in sodium salicylate- treated plants, except with 800mg/l which increased gibbereilins at day 80. Cytokinin content was also increased in ripened grains with all concentrations used.
