Effect of priming on growth, biochemical parameters and mineral composition of different cultivars of coriander (Coriandrum sativum L.) under salt stress

Abstract
At Higher Institute of Agriculture of Chott Mariem, Sousse, Tunisia, this study was conducted to evaluate the interactive effect of salinity and seed priming on coriander. The experiment was carried out in completely randomized design with three replications consisting of four coriander genotypes (Tunisian cv, Algerian cv, Syrian cv and Egyptian cv) at two seed conditions (seed priming with 4 g/l NaCl for 12h or no seed priming). Results revealed that seed priming and salinity had significantly (p≤0.05) affected all the parameters under study. On the first hand, salinity stress had adversely affected growth, chlorophyll content, mineral composition (K[sup]+[/sup] and Ca[sup]2+[/sup]) of coriander in all genotypes. Also, it activated Na[sup]+[/sup] accumulation and synthesis of proline, soluble sugars and proteins. However, seed priming with NaCl had diminished the negative impact of salt stress in all cultivars and primed plants showed better response to salinity compared to unprimed plants. Maximum values were recorded in tolerant cultivar which is Tunisian one whereas minimum values were noted in sensitive cultivar (Algerian cv).
