摘要 [目的]筛选耐盐性较强的葡萄品种,为盐碱地葡萄栽培品种选择提供依据。[方法]以盆栽1年生扦插葡萄苗为试材,进行持续盐胁迫处理,测定相关生长指标和生理指标,运用隶属函数法分析10个葡萄品种间的耐盐性。[结果]盐胁迫后,不同品种的葡萄对盐胁迫的响应程度不同,10个葡萄品种生长减缓,生物量下降,相对电导率和丙二醛含量不同程度增加。[结论]春光、金光和香妃耐盐性较好,巨玫瑰和摩尔多瓦耐盐性较差。

Abstract [Objective] To select the grape varieties with strong salt tolerance,and provide the basis for the selection of grape varieties in saline alkali area.[Method] The pot annual cuttage grape seedlings were used as the test material to carry out continuous salt stress treatment,and the related growth and physiological indexes were measured.The salt tolerance of 10 grape varieties was analyzed by membership function method.[Result]After salt stress,the response degree of different varieties to salt stress was different,the growth of 10 grape varieties slowed down,biomass decreased,relative conductivity and malondialdehyde content increased to different degrees.[Conclusion]The salt tolerance of Chunguang,Jinguang and Xiangfei was better and that of Jumeigui and Moldova was poor.

我国盐碱地总面积约3 600万hm2,作为耕地潜在的后备资源,如何合理利用已越来越受到高度关注[1]。在我国环渤海地区高效现代农业发展迅速,葡萄为耐盐性较强的果树,在盐碱地上种植具有发展潜力[2]。尽管葡萄属于较耐盐果树,但葡萄对NaCl最为敏感[3]。葡萄不同品种间耐盐性存在差异,因此研究筛选耐盐性强的葡萄品种,对解决我国盐碱地葡萄生产的现实问题具有重要意义。
盐胁迫下植物组织会产生一系列生理变化,可作为植物耐盐性鉴定的指标,如形态指标、生长量指标、土壤含盐量指标和生理生化指标[4]。近年来,国内外学者围绕……
