| 摘 要： | 用调制剂和烯效唑处理育苗床土，在生长箱内对三叶期的水稻秧苗高强度接种病原菌。结果表明：调制剂和烯效唑处理的秧苗体内超氧化物歧化酶(SOD)、过氧化物酶(POD)、多酚氧化酶(PPO)与苯丙氨酸解氨酶(PAL)都比对照提前到达酶活高峰；调制刺处理的秧苗具有2个酶活高峰，烯效唑处理的秧苗除PPO具有2个酶活性峰外，其余酶都只具有1个酶活峰，且调制剂处理的秧苗体内酶活最高峰高于烯效唑处理的秧苗体内酶活最高峰。

| Abstract: | In nursery soil treated with S3307, and seedling-stimulating agent, three-leaf rice seedlings were inoculated with pathogenic bacteria under higher intensity. The results indicated that the enzyme activity of SOD, POD, PPO and PAL in rice seedlings treated with S3307 and seedling-stimulating agent reaches the peaks of enzyme activity earlier than the control. Rice seedlings treated with seedling-stimulating agent have two enzyme activity peaks, while rice seedlings treated with S3307has only one enzyme activity peak except that of PPO. Rice seedlings treated with seedling-stimulating agent have higher enzyme activity peaks than rice seedlings treated with S3307. |
