Abstract:
Three varieties of summer squash and six pieces of germplasm were used as test materials.The inhibition effects of four inducers(5 g?L-1 NaHCO3，5.706 g?L-1 K2HPO4，2.62 g?L-1 K2SiO3 and RM(0.188 g?L-1 riboflavin+0.746 g?L-1 methionine) on powdery mildew，yield，soluble sugar content and soluble protein content were studied to search alternative technologies of chemical pesticide to prevent squash powdery mildew.The results showed that the inhibition effect on powdery mildew of summer squash was 5.706 g?L-1 K2HPO4＞5 g?L-1 NaHCO3＞2.62 g?L-1 K2SiO3＞RM.To a certain degree,the four kinds of inducer treatments could postpone effectively powdery mildew occurrence and promote plant growth.The effect on individual plant yield of summer squash had no obvious regularity，but all were higher than control.The effect of 5.706 g?L-1 K2HPO4 and RM treatment were better.Plant added yield was positively correlated to increase resistance，the correlation coefficient was 0.693.The soluble protein content and soluble sugar content of summer squash leaf increased after treatments.Soluble sugar content increase was positively correlated to increasing resistance，the correlation coefficient was 0.754.The measures induced the summer squash own stress reaction and formation of powdery mildew resistant mechanism by adjusting the endogenous type and content of nutrients.
