摘要
实验研究了3个苹果品种被轮纹病菌(Botryosphaeriaberengrianaf.piricola)侵染后苹果枝干轮纹病防御酶系的变化。结果表明,在受病菌侵染后,苯丙氨酸解氨酶(PAL)、超氧化物歧化酶(SOD)、过氧化物酶(POD)和多酚氧化酶(PPO)均表现为先升后降的趋势,且抗病品种的峰值出现较晚。抗病品种鸡冠的PAL、SOD和POD活性变化峰值和均值要高于国光和富士,而PPO活性变化的峰值和均值则低于国光和富士。
The activities of defendant enzymes were studied in 3 apple cultivars with different level of resistance to apple ring rot disease on stem by inoculated the Botryosphaeria berengriana f. piricola. The activities of phenylanine ammonialyase(PAL) superoxide dismutase(SOD), peroxidase(POD) and polyphenoloxidase(PPO) in 3 apple cultivars all were strong at first and then declined and the appearance of the induced peak followed by inoculation in resistant cultivar (Jiguan) appeared later than that in susceptible cultivars (Ralls Janet and Fuji). The maximum and average value of PAL, SOD and POD in Jiguan were higher than those in Ralls Janet and Fuji but for the maximum and average value of PPO, Jiguan was the lowest one.
