| 摘 要： | 通过对电导法、人工模拟气候鉴定法、叶绿素测定法的鉴定结果与夏季自然鉴定结果的相关性分析表明：前两种方法能基本反映大白菜品种的耐热性。叶片细胞电解质渗透率及热害指数与高温结球率之间有极显著的负相关性。而高温处理后叶绿素含量变化率没有一定的规律性，不能作为一个耐热生理指标。

| Abstract: | The correlation analyses among the data of electric conductivity, growth chamber test, chlorophyll content and summer natural field test showed that the former two methods could reflect the heat tolerance of heading Chinese cabbage. The electrolyte leakage rate of the blade cell and the heat damage index had a markable negative correlation with heading rate under high temperature. Whereas, after high temperature treatment, chlorophyll content did not expressed relationship with head formation, and could not be used as a physiological trait for heat tolerance. |
