黄瓜耐盐性与耐盐相关基因的研究进展

黄瓜是重要的设施蔬菜之一,由于其根系具有脆弱、好气、分布较浅的特点,对盐渍环境适应性较差,土壤盐渍化已成为影响其产量和品质的主要限制因素。本文主要从光合作用、离子毒害、细胞膜和抗氧化酶等角度阐述了黄瓜对盐胁迫的反应及其基本的耐盐机理,介绍了黄瓜耐盐(包括与Na~+/K~+、植物激素和活性氧的调节)相关基因的研究进展,并指出了黄瓜耐盐性研究中存在的问题,旨在为揭示黄瓜的耐盐机理与耐盐育种提供理论参考。

Research Progress on Cucumber Salt Tolerance and Salt Tolerance Related Genes

Cucumber is one of the important greenhouse vegetables．Because of its fragile root system，good atmosphere and shallow distribution，its adaptability to saline environment is lower． Soil salinization has become a main limiting factor affecting its yield and quality．This paper described the response of cucumber to salt stress and its basic salt tolerance mechanism from perspectives of photosynthesis，ion toxicity，cell membrane and antioxidant enzymes，etc. angles；introduced the research progress on cucumber salt tolerance related genes including genes related to Na⁺/K⁺ regulation， plant hormone regulation and ROS regulation；and also pointed out problems existing in studying salt tolerance of cucumber，aiming at providing theoretical references for revealing cucumber salt tolerance mechanism and breeding of salt tolerant cucumber varieties
