摘要
以贺兰山东麓地区种植和繁育的"赤霞珠"、"蛇龙珠"、"梅鹿辄"等主要酿酒葡萄品种为试材,采用田间调查和实验室测量的方法,研究了宁夏贺兰山东麓地区葡萄树及葡萄种苗卷叶病的发病情况及葡萄卷叶病对葡萄树的影响。结果表明:葡萄树卷叶病平均感病率为4.66%,葡萄卷叶病使得葡萄的产量下降,品质降低,SPAD值和光合速率下降;2012—2014年,宁夏主栽的酿酒葡萄品种种苗卷叶病的带毒率逐年降低。
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.
