To study the effect of salicylic acid (SA) on the amount and quality of oil in different regions of sunflower inflorescence, a factorial experiment was conducted based on randomized complete block design with 3 replications at the University of Mohaghegh Ardabili, Ardabil, Iran. Salicylic acid at concentrations of 0, 0.1, and 0.2 g L-1 were sprayed on whole plant at 3 stages (twice before flowe...

The action of salicylic acid (SA) has been well investigated in plant resistance against pathogen attacks but its role may be extended to a more global anti-stress plant cell strategy. The expression of defense-related functions may be also enhanced by elevated hexose levels. To verify if there exists a relation between these two defense programs, SA effect on soluble acid invertase (EC 3.2.1.2...
