摘要
采后结球白菜和甘蓝生长点及其周围未伸展叶片过氧化物酶活性最高，外层成熟叶片其次，中间叶片活性最低，不同叶位叶片过氧化物酶活性与呼吸强度呈很好的正相关（ｒ＝０．９８８９）。生长点及不同叶位叶片ＩＡＡ氧化酶活性没有规律性变化，而叶片离层部位此酶活性与叶片的成熟衰老呈正相关。
Peroxidase activity in the apical cone, inner- and outer- leaves was higher than that inmiddle leaves of headed vegetables (Chinese cabbage Brassica pekinensis R. and cabbageBrassica var. capitata). There was a good relationship between peroxidase activity and respiration rate in differently positioned leaves of Chinese cabbage (r = 0.9889). IAA-oxidase activity in the abscission zone of leaves showed a positive relationship with the senescence ofthe leaves.
