【Abstract】 Virosis had heavy influences on the output and quality of dishcloth gourd. Incidence of disease was 25%～40% in the whole or 100% in some individual fields. Single-plant outpout was reduced nearly by 30%, and the yield was reduced about 3.2t per hectare. The fruits of diseased plants were malformed. The texture was hard, and with bad flavour. The nutrition composition including vitamin C, rough-fat, soluble sugar, protein and calcium was decreased by 28.97%, 18.75%, 9.09%, 4.07% and 5.22% respectively.更多还原
