| 摘 要： | １９９０～１９９２年室内和大田接菌观察３个不同致病型菌株对水稻成株期致病力，ＴＨＡ的菌株１４７￣＃致病力最强。该菌具菌核萌发快，菌丝长势强，病斑潜伏期最短。还对品种、菌株、施肥量、密度等４个因素３个水平对病发生发展影响，及田间病害扩展动态进行研究。

| Abstract: | omparative study of the pathogenicity of 3 isolates of R.solani belonged to3different pathogenic-type from Guizhou to rice adult-plant was conducted by artificalinoculation in pot-culture and the field in 1990-1992. The pathogenicity of No 147 iso-late belonged to ThA is the best.It sho wed fast germination of the sclerotia,flour-ishing growth of the mycelia,and short latent period showed the lesion on riceplant.This paper discussed also the relationship between rece varities, isolates,plant-ing density and manuring to disease development,and the dynamic of disease develop-ment in the field. |
