摘要
番茄是广泛种植的作物,但由于土壤次生盐渍化问题,导致了番茄产量下降。本文主要介绍了盐渍化对番茄生长发育的危害,并从植株水平、细胞水平和分子水平阐述了番茄抗盐性的机理。在此基础上,进一步比较分析了化学措施、基因工程及微生物接种等抗盐技术的有效性及其机理,表明了有机无机物配施、抗盐锻炼、抗盐砧木嫁接及丛枝真菌接种技术等传统措施对促进番茄抗盐性均有良好的效应;利用农杆菌介导法和花粉管通道途径等现代转多基因技术在增强番茄抗盐性方面取得了良好的效果。同时,应加强传统措施和现代技术的融合优化,从而增强番茄抗盐的能力。
Tomato is a major food crop worldwide.Increasingsoil salinity has become one of the common abiotic stresses affecting the vegetative growth and fruit yield of tomato plants.This article articulates the mechanisms of salt tolerance of tomato as viewed from the plant,cellular,and molecular levels.Furthermore,effective alleviation of the salt stress by chemical,genetic engineering,and microbial manipulations for the tomato plants is discussed.The conventional approaches,such as theintegrated application of organic and inorganic fertilizers,resistance exercise as well as grafting and microbial inoculation,have played a vital role in the improvement of the conditions in the past.Recently,the genetically modified tomato crops viathe agrobacterium-mediated transformation or pollen tube also produced high levels of tolerance to salt for the plants.By integrating and optimizing the conventional and modern technologies,the effort in combating,the salinity increase could be further advanced.
