Abstract: The two-factor (temperature and time of heat shock) quadratic regression orthogonal rotation combination design was used to study the effects of heat shock treatment on seedling heat-durability of two cabbage varieties with different heat tolerance, by measuring the amount of electrolyte leakage of cellular membrane. The result showed that the leaf cell membrane permeability of heat sensitive variety increased more than that of heat tolerant variety after heat shock treatment. The cell membrane thermostability had extremely remarkable regression with the temperature, and the optimum combination of heat shock was 42℃ for 2.3 h.

Key words: Cabbage, Heat thermostability, The amount of electrolyte leakage
