| 摘要: |
| 共分析了采自全国各地的73株赤霉菌,发现该菌在我国各地普遍以异核体性存在。分析结果指示异核体约占69.9%,纯核体约占30.1%,在同一菌丝的不同部位遗传型不同的核分布很不均匀。以多标记的营养缺陷突变型株作为亲本,采用一种简便的方法强制合成了异核体。 |

| Abstract: |
| The natural heterokaryons of Fusarium moniliforme Sheld,the causative agent of bakanae disease,were readily isolated with a diff- ential culture medium from blighten rice seedlings in open fields.These heterokaryons were found to be composed of three different clones, designated respectively as purple,red and white phenotypes,or two or even only one of them.Most of them were of the red type,the purple one being the next and the white one the least.However,the purple phenotype was more virulent than either t... |
