摘　　要：土地盐渍化是一个全球性的问题,开展大豆品种耐盐性评价在提高大豆产量、扩大其种植面积方面具有重要意义。本研究在测定Na Cl处理下大豆萌发率、芽长、丙二醛含量、脯氨酸含量等指标的基础上利用隶属函数对指标数据进行分析,并完成供试15个黄淮海大豆品种(系)的耐盐性评价,鉴定出阜107-3、徐豆10、齐黄34、山宁17、临豆10、齐黄35、菏豆21、嘉豆43共8个耐盐性较强的大豆品种(系),同时初步研究了芽期和苗期耐盐性的综合鉴定方法。Soil salinization is a global problem, and salt - tolerance evaluation of soybean varieties has great significance in improving soybean yield and expending cultivated area. In this study, the germination rate, germinal length, malonaldehyde （MDA） and proline （PRO） contents under NaC1 treatment were measured to evaluate the salt tolerance of 15 soybean germplasms using membership function. Among which, Fu 107 - 3, Xudou 10, Qihuang 34, Shanning 17, Lindou 10, Qihuang 35, Hedou 21 and Jiadou 43 with higher salt tolerance were suitable for cultivating in saline areas of the Huang - Huai - Hai Region. The dynamic qualification system was preliminarily developed to identify the salt tolerance of soybean at germination and seedling stages.
