一种引起花生严重矮化的黄瓜花叶病毒的(CMV)株系鉴定

IDENTIFICATION OF A STRAIN OF CUCUMBER MOSAIC VIRUS(CMV)CAUSING PEANUT SEVERE STUNTING

根据病毒生物学特性、颗粒形态和血清学性质,明确由山东泰安花生矮化病株上分离的一个病毒分离物为黄瓜花叶病毒(CMV)一个株系,并暂定名为CMV花生矮化株系(CMV-CS)。CMV-CS引起花生叶片显著变小,植株严重矮化以及蚜传效率低而不同于我国花生上流行比较普遍的CMV-CA株系.

On the basis of biological properties,morphology and serology of thevirus,a isolate of the virus from a peanut stunt plant was identified as astrain of cucumber mosaic virus,designated tentatively as a CMV peanut stuntstrain,(CMV-CS).CMV-CS is differed from CMV-CA by indusing obvioussmaller leaves and severe stunting of the peanut,and less efficiency of aphidtransmission.
