摘  要:
水稻徒长苗在近几年常发生并且较普遍,是广大农民群众十分关心的一大难题,为了进一步探讨徒长苗的类型及其发生原因,从1990~1991年进行了室内徒长苗病菌分离和赤霉素处理土壤、种子及盆栽和田间生物试验。经两年的试验结果表明,淡黄色徒长苗有两种,一种是恶苗病菌侵入而发生的病苗,属于死亡型;另一种是病菌分泌出赤霉素刺激稻苗而产生的淡黄色徒长苗,属于恢复型,其恢复率可达89.5~98.7%左右。

Studying on the sorts of overgrown rice seedlings and the cause of ac- cess.We have seperated disease germ from overgrown seedlings and treat- ed soil and seeds with gibberellin.The tests were going through pot incu- bation and field from 1990 to 1991.The experimental results showed that there were two sorts of pale yellowishgreen overgrown seedlings.One sort which called dead type is desease seedlings because of Gibberella fujikur- oi.The other sort which called restorer type is caused by stimulating of secretory gibberellin from desease germ.The restorer rate is 89.5~ 98.7%.
