摘　　要：盐胁迫是威胁作物生长的主要非生物胁迫之一。在高盐条件下,植物可能遭受渗透、离子和氧化胁迫,从而抑制生长和发育。为了应对盐胁迫带来的伤害,植物在进化过程中形成了一系列耐受机制,包括在细胞质中积累相容溶质进行渗透调节,通过增强抗氧化酶的活性清除活性氧,以及通过控制Na^(+)吸收和运输来调节Na^(+)/K^(+)稳态等。从盐胁迫对植物的危害、植物在盐胁迫下的调节机制和瓜菜作物耐盐相关基因的挖掘等方面综述了瓜菜作物耐盐性的研究进展,为我国土地盐渍化治理以及植物种质资源改良提供参考。Salt stress is one of the major abiotic stresses threatening crop growth.Under high salinity conditions,plants may be subjected to osmotic,ionic and oxidative stresses while their growth and development are inhibited.In response to these stresses,plants develop a range of tolerance mechanisms,including osmotic regulation of the accumulation of compatible solutes in the cytoplasm,scavenging reactive oxygen species by enhancing the activity of antioxidant enzymes,and regulating Na^(+)/K^(+)homeostasis by controlling Na^(+)uptake and transport.In this paper,the research progress of salt tolerance in cucurbits and vegetables were reviewed,including the damage of salt stress to plants,the regulation mechanism of plants under salt stress,and the salt tolerance related genes of cucurbits and vegetables.This paper can provide reference for the improvement of saline soil and plant germplasm resources in China.
