Abstract:

The effect of rain-shelter film polyethylene(PE)fabric Coverlys TF150® on canopy,fruit microenvironment and fruit quality were investigated by using grape‘Miguang’(Vitis vinifera × V. labrusca)as test material. The experimental results from two consecutive years showed that the light transmittance under CoverlysTF150® is 11.91% lower than that under polyolefin(PO)film,which reduced the temperature and humidity around the fruit zone and alleviated the stress of high temperature and strong light. CoverlysTF150® increased fruit size and the content of soluble solids,anthocyanins,total phenols,flavonoids and flavanols,while reduced titratable acid content. In 2020 and 2021,fruit hundred-grain weight increased by 2.15% and 2.46%,fruit soluble solids content increased by 3.70% and 3.04%,fruit titratable acid content decreased by 17.90% and 10.53%,fruit anthocyanin content increased by 18.33% and 11.91%,total phenol content increased by 23.30% and 13.07%,flavonoids content increased by 24.00% and 19.43%,flavanol content increased by 18.20% and 15.58%,respectively. Coverlys TF150® increased the content of terpenes aromas,especially linalool,while decreased the content of C6 aldehydes such as hexanal aroma.

Key words: grape, rain-shelter cultivation, PE fabric Coverlys TF150?, microenvironment, fruit quality
