Abstract

Soil salinization and/or alkalization is a major constraint to crop production worldwide. Approximately 60% of the cultivated land is affected by salt, over half of which is alkalized. Alkaline soils are characterized by high alkalinity and typically high salinity, which creates a complex saline-alkaline (SA) stress that affects plant growth. Rice cultivation has been accepted as an important strategy for effective utilization of SA land if water is available for irrigation. Nevertheless, as a salt-sensitive plant, rice plants suffer severe SA-induced damage, which results in poor plant growth and grain yield. Various approaches have been employed to improve rice productivity in SA land. Among them, the priming technique has emerged as a powerful method for enhancing SA tolerance in rice plants. In this review, we summarized how SA stress damages rice plants, and then presented how priming treatment can mitigate such damage.

水稻耐盐碱启动:当前知识和未来挑战
土壤盐碱化和/或碱化是全球作物生产的主要制约因素。大约60%的耕地受到盐的影响,其中一半以上是碱化的。碱性土壤具有高碱度和高盐度的特点,造成复杂的盐碱胁迫,影响植物生长。水稻种植已被认为是有效利用SA土地的重要策略,如果有足够的水用于灌溉。然而,作为一种盐敏感植物,水稻植株受到严重的盐害,导致植株生长和籽粒产量下降。已经采用了各种方法来提高SA土地上的水稻产量。其中,引物技术已成为提高水稻耐SA能力的有力手段。在这篇综述中,我们概述了SA胁迫如何损害水稻植株,然后介绍了启动处理如何减轻这种损害。
