Seed vigor is a complex physiological trait required to ensure the rapid and uniform emergence of plants in the field under different environmental conditions. Therefore, salicylic acid (SA, 0.5 mM) and calcium (Ca2+, 50 mM) priming were used as exogenous growth enhancers to stimulate wheat (Triticum durum Desf. cv. Yelken) seed vigor under high salinity. The main aim was to address whether priming of wheat with SA, Ca2+ and SA+Ca (SA, 0.5 mM + Ca2+, 50 mM; their combination) could bring about supplementary agronomic benefits particularly under stressful environments such as salinity. Exogenous application of SA or Ca2+ alone improved plant behavior in the presence of salinity stress. Nevertheless, the best results in terms of growth, seed vigor and total phenolic - flavonoids, chlorophyll - carotenoids contents and phenylalanine ammonia-lyase (PAL), ascorbic acide oxidase (AAO) activities and lipid peroxidation levels (LPO) were obtained in response to the combined SA+Ca treatment.
种子活力是一种复杂的生理特性，对于确保植物在不同环境条件下于田间快速、均匀地萌发至关重要。因此，水杨酸（SA，0.5 mM）和钙（Ca2+，50 mM）引发处理被用作外源生长促进剂，以在高盐度条件下刺激小麦（硬粒小麦品种Yelken）种子活力。主要目的是探讨用SA、Ca2+以及SA+Ca（SA，0.5 mM + Ca2+，50 mM；二者组合）对小麦进行引发处理是否能带来额外的农艺效益，特别是在诸如盐度等胁迫环境下。单独外源施用SA或Ca2+可在盐胁迫条件下改善植株表现。然而，就生长、种子活力以及总酚类 - 黄酮类、叶绿素 - 类胡萝卜素含量和苯丙氨酸解氨酶（PAL）、抗坏血酸氧化酶（AAO）活性以及脂质过氧化水平（LPO）而言，SA+Ca组合处理获得了最佳结果。
