| 摘 要： | 自 2 0世纪 6 0年代发现栗疫病 (干枯病 )弱毒菌系以来 ,关于弱毒菌系的研究不断深入。本文阐述了弱毒因子的传递方式、机理 ,强、弱毒菌系混合体系 ,两类菌丝的超微结构以及生理特性。栗疫菌弱毒菌系在自然界的传播受诸多因素的影响 ,弱毒菌株菌丝生长较慢 ,产孢能力较低 ,因而同强毒力菌系竞争的能力较弱

| Abstract: | The hypovirulent strains of Cryphonectria parasitica have been researched since they were found in 1960's. This paper deals with the transfer method and mechanism of hypovirulence factors; the mixed system of virulent and hypovirulent strains; the super microcosmic structure and physiological characters in the two kinds of hyphae. The hypovirulent strains have less competition capability compared with virulent ones in natural world by the facts of hyphae growth slowly and spores production difficulty. |
