在大田栽培和自然光的条件下,以欧洲葡萄(Vitis vinifera L.)品种"赤霞珠"(Cabernet Sauvignon)为材料,通过人工增加紫外线(UV)-B辐射量0 μW/cm~2(CK组)、10.2 μW/cm~2 (T1组)、20.7 μW/cm~2 (T2组)和30.5 μW/cm~2 (T3组),研究了紫外线增强对葡萄成熟期果实发育和品质的影响.结果表明:随着UV-B辐射量的增加,葡萄果实大小及产量等显著降低,葡萄着色指数下降;其主要理化指标,如还原糖、总酸、糖酸比(A/S)、可溶性固形物(TSS)下降趋势显著(表现为CK>T1>T2>T3);而且UV-B越强,降低程度越大,并在一定程度上会延缓葡萄生长.

On the basis of outdoor natural sunlight, four radiation intensities including 0μW/cm~2 (CK), 10.2 μW/cm~2 (T1), 20.7 μW/cm~2 (T2) and 30.5 μW/cm~2 of ultraviolet-B radiation were used to study their effects on growth and quality of the Vitis vinifera Cabernet Sauvignon. The results showed that enhanced ultraviolet radiation decreased grape size, yield and fruit coloration index. At the same time physiochemical indexes, such as reducing sugar, Titrable acid, A∕S and TSS were down (the sequence was: CK>T1>T2>T3) and the growth of grape were retarded to a certain extent.
