Abstract:
On the basis of a sampling survey and lab measurements，wine grape,such as ‘Cabernet Sauvignon’，‘Cabernet Gernischt’ and ‘Merlot’，planted and propagated in the eastern region of Helan Mountain were used to study the effect and the infection rate of grapevine leafroll-associated virus (GLRaV).The research results showed that the average infection rate of GLRaV was 4.66%，compared with the healthy plants，the output of infected plants by GLRaV was decreased，quality was degraded，the value of SPAD and Pn was reduced.Fortunately，the infection rate of GLRaV on the grape seedlings that propagated in the eastern region of Helan Mountain was decreasd year by year form 2012 to 2014.
