Abstract:
Using 6-year-old ‘Chardonnay’ grape as the test material,the content changes of total sugar,organic acid,total phenol,flavonoid,reduced glutathione and free amino acid were determined by spraying different concentrations of yeast polysaccharide diluent at different stages and different parts after flowering,so as to explore the different spraying methods on leaf curtain and cluster during the growth and development of ‘Chardonnay’ grape and effect of concentration of yeast polysaccharide solution on fruit quality.The results showed that spraying yeast polysaccharide solution on leaves and clusters could promote the accumulation of effective components in ‘Chardonnay’ grape,and the effect of foliar spraying was more significant than that of clusters.Compared with the control,the total sugar increased by 10.82%,organic acid decreased by 14.40%,total phenol increased by 26.61%,flavonoid increased by 47.92%,reduced glutathione increased by 156.50%,and free amino acid increased by 50.28%.However,considering the actual production situation,the cluster spraying was more suitable for production.Therefore,spraying 200 times yeast polysaccharide solution on the cluster can significantly improve the fruit quality of ‘Chardonnay’ grape,which is suitable for popularization and application.
