摘要： A pot experiment was conducted to study the effects of spraying leaves of Chinese cabbage seedlings with different concentrations of indoleacetic acid (IAA) on the physiological characteristics of Chinese cabbage seedlings under aluminum stress. The results showed that, spraying IAA could increase photosynthetic pigment content, such as chlorophyll a, chlorophyll b and carotenoid. When the concentration of IAA was 200 mu mol . L-1, the contents of SOD, POD, CAT and soluble protein were 17.85%, 20.70%, 40.63% and 22.56% higher than CK respectively, which indicated that spraying IAA could alleviate the effect of aluminum on plant physiology system destruction, and promote the growth and development of plant tissue. The 200 mu mol . L-1 was the best.
