| 摘 要： | 试验证明, 硫与三环唑(7∶1) 混配成悬浮剂, 对抑制稻瘟菌的菌丝生长、分生孢子萌发、附着胞的形成以及产孢能力等都具有较明显的协同增效作用, 协同作用比率(S R ) 分别为2. 1、2. 5、1. 8 及8. 6。混配剂集合了硫及三环唑两者的优点, 并显示出耐雨水冲刷、持效期长的特点。田间试验亦表明其防病增产效果比较显著。

| Abstract: | The effect of 20% seed coating formulation (SCF)for soaking and pregermination of rice seed on the growth, development and enzyme activities related to the disease resistance in rice seedling were studied. The results indicated that 20% SCF obviously increased the emergency ratio, survival ratio, plant height, root length, tillering rate, the content of soluble protein, and anti disease ability of seedling. The active oxygen metabolism was ameliorated and Malondialdehyde (MDA) content was decreased. The activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and polyphenoloxidase (PPO) in rice seedling were stimulated by using 20% SCF treatment. The results showed that 20% SCF played an important role in retarding senescence and inducing the disease resistance. |
