| 摘 要： | 选用8份不同耐湿基因型的普通白菜（小白菜）品种，在5种不同温度条件下对6片叶苗龄的幼苗分别进行高湿处理，研究普通白菜的耐湿性鉴定方法。最终确定以土壤湿度饱和、相对空气湿度95%、30 ℃/ 20 ℃（昼12 h/夜12 h）处理幼苗6 d，作为普通白菜耐湿性差异的鉴定条件|以叶片褪绿面积和程度作为湿害分级指标，并以此调查湿害指数，从而鉴定品种的耐湿性。

| 关 键 词： | 普通白菜（小白菜） 耐湿性 鉴定 湿害指数 |

| Abstract: | 8 pakchoi genotypes with different water-logging tolerance were selected and treated under 5 different temperature conditions for high humidity,when their seedling leaves were 6,aiming at studying the identification method for pakchoi water-logging tolerance.Finally the saturated soil moisture,95% of relative air humidity,30 ℃/20 ℃ of day 12 h/night 12 h treatment for seedlings of 6 days were determined as identification condition for differences of pakchoi water-logging tolerance.The chlorosis size and degree of chlorotic leaf blades were taken as the grading index for wet injury,and thus to identify the water-logging tolerance of the variety. |
