摘  要:
以渭北旱塬5年生酿酒葡萄"赤霞珠"为试材,生长季节研究了4种不同叶幕厚度(40、60、80cm和对照)下葡萄叶片光合指标、冠层光合特性,以及果实酚类物质含量的差异。结果表明:生长期控制叶幕厚度能在一定程度上提高"赤霞珠"葡萄叶片和冠层的光合特性,较薄的叶幕能显著提高果实中糖、花色苷、种子总酚以及不同分子大小聚合色素的含量,但叶幕厚度对"赤霞珠"葡萄果皮中总酚、果皮和种子中总类黄酮含量无影响。总体而言,渭北旱塬"赤霞珠"葡萄在生长季节的叶幕厚度以40cm为宜。

摘  要:
5-year-old‘Carbernet Sauvignon'(Vitis vinifera L.)grape in Weibei dryland was used as materials,photosynthesis parameters of leaf and canopy and fruit quality were determined for grape pruned with different canopy thicknesses of 40 cm,60cm,80 cm and control.The results showed that photosynthesis capacity increased with decreasing canopy thickness.Content of sugars in berry,anthocyanins in skin,total phenolics in seed and three types of polypigment increased obviously for the thinner canopy compared to the thicker ones and control.However,no significant effect of canopy thickness was found on total phenolics content in skin,and total flavonoid content in skin and seed.Forty centimeters of canopy thickness might be optimum for‘Carbernet Sauvignon'grapes in Weibei Plateau.
