Hydropriming, Ascorbic and Salicylic Acid Influence on Germination of Agropyron elongatum Host. Seeds Under Salt Stress

A. Tavili, S. Zare and A. Enayati

Abstract:
The objective of this study was to evaluate the effects of ascorbic acid and salicylic acid pretreatment in addition to hydropriming on enhancement of seed germination of Agropyron elongatum under salt stress. The experimental design was two factors factorial based on a completely randomized design. Treatments were the combination of four levels of salt stress (0, -0.3, -0.6 and -0.9 MPa) in three concentrations of ascorbic acid and salicylic acid separately (100, 200 and 300 mg L-1) and three levels of hydropriming (0 as a control, 12 and 18 h) with four replications. Results indicated that an increase in salt stress decreased germination components such as germination percentage and rate, coleoptile, radicle and seedling length and vigor index. Salicylic acid pretreatment and hydropriming did not significantly affect germination, but ascorbic acid spatially it's 300 mg L-1 concentration alleviated the adverse effects of salinity in all germination characteristics. Totally, it is concluded that ascorbic acid pretreatment results in improvement germination properties of A. elongatum under salt stress condition which in turn increases the resistance of A. elongatum against salt stress in germination phase.
