摘要
目前葡萄抗病研究主要采用田间自然发病调查和人工接种2种方法,病毒病用免疫学、分子生物学和传统生物学检测。葡萄抗病性分级标准有反应型和严重度2种标准。葡萄抗病性与品种、氮代谢、酶活性变化和叶绿素有显著相关,但与物质代谢、叶幕结构的相关性目前还存在歧义。防治技术主要是选用抗病品种、加强测报、及时喷药。
At present, the disease resistance of grapevine was studied by means of field identification and artificial inoculation, the virus disease was detected by immunological, molecular biology and tra- ditional biology. There were two degrees of standards to identify resistances of grapevine, which were infection type and severity. It showed disease resistance had high correlations with grape varieties, nitrogen metabolism, the change of enzymes activity and the content of chlorophyll. However, the relationship of the disease resistance of grape with material metabolism and leaf canopy structure was uncertain. As a result, the disease could controlled through choosing resistant varieties, reinforcing disease -forecasting and using fungicide timely.
