摘要
刺槐花叶是我国北方刺槐(Robinia pseudo-acacia)常见病害。1987～1989年调查河南开封、河北滦县和北京部分地区,刺槐花叶发病率为20％～50％。该病害主要特征是:叶片出现浅绿与绿色相间带有疱疹的花叶症状,叶缘波状扭曲,叶片畸形,显著变窄、变小。对从北京密云刺槐花叶病树获得的一个病毒分离物做寄主范围、传播特性和血清学性质研究,初步明确该分离物为花生矮化病毒(Peanut stunt virus,PSV),并称为PSV刺槐分离物,即PSV-R。
Black locust mosaic is a common disease of black locust ( Robinia pseudo-acacia) in Northern China. The disease incidence ranged from 20% to 50% on the basis of the surveys made in some locations of Henan, Hebei Provinces and Beijing. A virus from a diseased tree was identified as a Robinia isolate of peanut stunt virus ( PSV-R ), on the basis of biological and serological properties of the virus. Of 23 species tested, the virus infected 15 species of plants including black locust, peanut ( Arachis hypo- gaea ) , soybean ( Glycine max ) ,cowpea ( Vigna unquicttlata ) , Chenopodium amaranticoh, etc. The virus was transmitted by Aphis craccivora Koch in a non-persistent manner. The thermal inactivation point was 55-60℃, dilution end point 10-4-10-5 and longevity in vitro 10 days. Serologically the virus was closely related to PSV mild strain and distantly related to cucumber mosaic virus CA strain.
