Effect of Shade Netting on the Microenvironment and Quality of'Pinot Noir'Grape Berries in the Hexi Corridor
摘要
Abstract
[Objective]To address the problems of rapid ripening of grape berries and low acid content caused by strong solar radiation and extreme high temperature in the Hexi Corridor region,The effect of green and black shade nets with 45%～95%shading on grapevine fruit quality was investigated,using the wine grapes'Pinot Noir'from Mogao Winery in Wuwei City as the experimental materials.[Methods]:The experiment set up three treatments,green net with 4 stitches,black net with 4 stitches,and black net with 6 stitches,with an unshaded control.The effects of different treatments on the surface tem-perature and light intensity of'Pinot Noir'grape berries,as well as on the sugar,acid,pH value,and phenolic compounds of the berries were measured.[Results]The results showed that both green and black nets improved the microclimatic condi-tions of the grape berries,significantly reduced the average light intensity and the average daily temperature around the Pinot noir berries,and mitigated the drastic changes in extreme temperatures and light intensity;All three shading treatments had the effect of increasing acid and decreasing sugar,and significantly elevated the total flavonoids,total polyphenols and proan-thocyanidins content in grape berries,but reduced the total anthocyanin content,in which the black with 6-stitches shading net elevated the effect,while the green net with 4-stitches reduced the total anthocyanin by the least amount.[Conclusion]The results of this study provide a scientific basis for the fine control of grapevine metabolite accumulation and wine quality for-mation in the Hexi Corridor grape production area.关键词
