摘　　要：研究了我国目前广泛栽培的30个不结球白菜品种种子萌发期的抗盐性,以期筛选出适合盐碱地种植的不结球白菜品种。采用水培的方法,测定了各品种在盐胁迫下的相对发芽率、相对胚芽长、相对胚鲜质量、相对胚根长和相对根毛区宽度等指标(各指标的相对值为盐处理与去离子水培养的比值),在此基础上分析各指标的隶属函数值,计算耐盐指数。结果表明,30个不结球白菜耐盐性差异较大,耐盐指数位于前3位的品种分别为四倍体矮脚黄(0.93)、秦白二号(0.68)和北京小杂56(0.61),改良605耐盐指数最低(0.05)。从耐盐等级分析结果可以看出,四倍体矮脚黄为高耐品种,秦白二号、北京小杂56两个品种为耐盐品种,郑研小包23、上海鸡毛菜、丰抗90等10个品种为中等耐盐品种,美味四季小白菜、郑白小包头、新优抗70、精品四月白等14个品种为盐敏感品种,而日本绿宝、改良605和矮抗青等3个品种为高感品种。bThe salinity tolerance of 30 non-heading Chinese cabbage varieties widely cultivated now at the seed germination stage was studied in this paper, aiming to screen suitable non-heading Chinese cabbage varieties for cultivation in saline soil. By the method of hydroponics, the relative germination rate, relative germ length, relative embryo fresh mass, relative radicle length and relative root hair length （ the relative value was equal to the ratio of salt treatment to deionized water culture） of all varieties under salt stress （NaCl） were measured, the membership function value of each index was analyzed, and then the salt tolerance index was calculated. The results showed that 30 non-heading Chinese cabbage varieties displayed quite different salt tolerance, the varieties with salt tolerance index in the top three were Sibeitiaijiaohuang （0.93） , Qinbai No. Ⅱ （0. 68） and Beijingxiaoza 56 （0 . 61） ,and the salt tolerance index of Gailiang 605 was the lowest（0. 05） . From salt tolerant rating analysis, Sibeitiaijiaohuang was a highly resistant variety, Qinbai No. Ⅱ and Beijingxiaoza 56 were salt-tolerant varieties, Zhengyanxiaobao 23 , Shanghaijimaocai, Fengkang 90 and other seven varieties were middle-tolerant varieties. Meiweisijixiaobaicai, Zhengbaixiaobaotou, Xinyoukang 70,Jingpinsiyuebai and other 10 varieties were salt-sensitive varieties. Japan Lubao, Gailiang 605 and Aikangqing were highly susceptible varieties.
