Abstract:

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 in fection 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.
