摘要:

为了探究外源物质对植物耐盐性的调控机理及进一步利用外源调节物质提高作物耐盐性,归纳了五大类传统植物激素(生长素、赤霉素、乙烯、脱落酸、细胞分裂素)以及褪黑素、水杨酸、多胺、油菜素类固醇、茉莉酸类等外源生长调节物质对盐胁迫下植物生长的调控情况。同时总结了硅、钙等离子类外源调节物对盐胁迫下植物生长的调节作用,多种外源调节物质可通过增强光合作用、提高渗透势、增加抗氧化酶活性及减少离子毒害等方式来减轻盐害。本文为进一步利用单一或复合外源调节物质来缓解作物盐害盐提供理论依据。

Abstract:

To explore the regulation mechanism of exogenous substances on plant salt tolerance and to further utilize exogenous regulatory substances to improve plant salt tolerance, we summarized the five categories of traditional plant hormones (auxin, gibberellin, ethylene, abscisic acid, and cytokinin), and exogenous growth regulators such as melatonin, salicylic acid, polyamine, brassinosteroid, jasmonic acid on plant growth regulation under salt stress. At the same time, we reviewed the regulation effect of silicon and calcium on plant growth under salt stress, indicated that various exogenous regulatory substances could reduce salt damage by enhancing photosynthesis, increasing osmotic potential, improving protecting enzyme activity and reducing ion toxicity. This study provides a theoretical basis for using the single or compound exogenous regulatory substances to alleviate crop salt damage in the future.

Key words: exogenous substances, salt stress, plant hormones, ionic exogenous regulator, salt resistance
