摘　　要：在不同海水浓度处理下,对23个生菜品种的种子发芽和植株的耐盐力进行鉴定,并对生菜品种的出苗率、耐盐指数、耐盐比率及100%海水处理下的成活率进行聚类分析。结果表明,不同生菜品种之间的耐盐性具有较大差异,中丰、南蔬、细叶苦苣Ⅰ3个生菜品种表现出较高的耐盐性。Salt resistance of 23 lettuce cultivars were identified at the stage of germination growth and plant growth under seawater treatments. Seedling emergence rate, tolerance index, tolerance ratio and survival rate of lettuce cultivars were evaluated by using cluster analysis. The results showed that the salt tolerance from different lettuce cultivars showed singnificant difference by using seawater treatment, the three cultivars Zhongfeng, Nanshu and Xiyekuju Ⅰ appeared in higher salt-tolerance. The salt resistance ability of lettuces could be screened at plant growth stage.
