| 摘 要： | 为了探讨枣树炭疽病发生与不同枣品种酶活性的关系,研究了6个枣品种田间炭疽病发生时相关酶的活性。结果表明:不同枣品种炭疽病的发生率和病情指数不同,相关酶的活性明显不同。POD、SOD、PAL等酶活性与品种抗性呈正相关,PPO活性与品种抗病性呈极显著的负相关。6个枣品种中,冬枣的POD、PAL、SOD活性最强,PPO活性最弱;梨枣的PPO活性最强。酶活性与田间炭疽病发生的调查结果吻合,冬枣和大雪枣对炭疽病有较高抗性,梨枣易感染炭疽病,对该病的抗性不强。

| Abstract: | In order to investigate the relationship between isozyme activity and anti-anthrax of jujube,the activities of the POD,SOD,PAL and PPO and anthrax occurrence in field of six cultivars of jujube were studied.The results demonstrated that activities of different isozymes in different cultivars of jujube were significantly different.There existed a positive correlation between the isozyme activities of POD,SOD,PAL and varietal resistance,but the activity of PPO was to assume extremely significantly negative co... |
