摘　　要：土壤盐渍化是蔬菜作物栽培生产中面临的主要非生物胁迫之一。南瓜(Cucurbita spp.)具有较强的盐胁迫耐受能力,也是黄瓜、西瓜、甜瓜等葫芦科蔬菜嫁接生产的砧木,选育耐盐性较强的南瓜品种有助于提高南瓜和葫芦科嫁接蔬菜的产量和经济效益。本文主要对南瓜耐盐性评价方法和耐盐种质资源筛选、南瓜耐盐性形成的生理机制、南瓜耐盐性状的遗传及相关耐盐基因等研究进展进行综述,并对今后的研究方向进行展望,以期为解析南瓜耐盐调控机制和选育耐盐性品种提供理论参考。Soil salinization is one of the main abiotic stresses in vegetable production.Pumpkin(Cucurbita spp.)displayed strong tolerance to salt stress and was used as rootstock in grafting cultivation of cucumber,melon and watermelon.Selection of pumpkin varieties with salt tolerance is helpful to improve the yield and economic benefits of pumpkin and Cucurbitaceae grafted vegetables.This paper summarized the research progress on evaluation methods for salt tolerance of Cucurbita and salt-tolerant Cucurbita germplasm screening,physiological mechanism in forming Cucurbita salt tolerance,inheritance of Cucurbita salt tolerance traits and related salt tolerance genes in Cucurbita.Furthermore,the paper also prospected the future research direction,hoping to provide more theoretical references for understanding the regulatory mechanism of pumpkin salt tolerance,and selection of salt tolerant varieties.
