- Fruit sphere microenvironments and berry phenolic content of Cabernet Sauvignon ( Vitis vinifera L.) cultivated under rain-shelter systems with coloured plastic film Jiang-Fei MENG Tian-Ci SHI Yong YU Li-Li ZUO Yu-Shi FU Qin WANG Zhen-Wen ZHANG Agrociencias rain grape quality light quality shelter system plastic films colour Rain-shelter cultivation has been proven an important cultivation method for grape-plantings in continental monsoon climate zones, of which white plastic films are the most common shelter material. However, while this method and material reduces the occurrence of the disease, it can also decrease the grape berry quality. Five colours (including red, yellow, blue, purple, and white) of plastic films were covered above Cabernet Sauvignon ( Vitis vinifera L.) grapevine rows before veraison. Rain-shelter cultivation reduced air temperature, wind speed, and total solar radiation and enhanced relative humidity in the fruit sphere of grapevines. For each particular colour plastic film, the irradiance of its corresponding spectrum band in the canopy of vines was higher than with other colour plastic films. Meanwhile, the blue plastic film treatment significantly promoted the accumulation of total phenolics, anthocyanins, flavonoids, tannins, and phenolic acids more than the other colours of plastic films. Blue plastic films are more beneficial for berry quality promotion of wine grapes, especially Cabernet Sauvignon, under rain-shelter cultivation in continental monsoon climate zones. 2017 artículo científico 0101-2061 https://www.redalyc.org/articulo.oa?id=395953544011 en http://www.redalyc.org/revista.oa?id=3959 Ciência e Tecnologia de Alimentos application/pdf Sociedade Brasileira de Ciência e Tecnologia de Alimentos Ciência e Tecnologia de Alimentos (Brasil) Num.4 Vol.37
