摘要
对仁用杏树各器官在不同生育期的多酚氧化酶 ( PPO)和超氧化物歧化酶( SOD)的含量及活性进行了测定与分析。结果表明 :各器官 PPO活性和 SOD活性在不同生育期存在较显著的差异 ,PPO与 SOD活性均与仁用杏树的生理代谢以及抗逆性有关 PPO可作为仁用杏树的抗逆性生化指标。
The content and activity of polyphenoloxidase(PPO) and superoxide Dismutase(SOD) of various organs of the kernel apricot were analysed,the results showed that there was significant difference in the activity of PPO and SOD among different growth period.The activity of PPO and SOD is related to physiology metablism and adverse circumstances resistance of the kernel apricot,and the former could be used as biochemical index of adverse circumstances resistance of kernel apricot.
