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...
