摘　　要：以6年生的鲜食葡萄"红地球"(‘Red Globe')为试材,研究主梢摘心及副梢处理对果实品质的影响。主梢超过第3道铁丝2~3片叶进行摘心,紧靠果穗上部的1个副梢留5片叶摘心,顶端留1个副梢,其余副梢全部抹除,结果枝顶端副梢留不同数量的叶片进行摘心。结果表明:不同的副梢处理方法较对照均提高了"红地球"葡萄果实的单粒质量、可溶性固形物、还原糖及果皮总花色苷的含量,其中顶端副梢留4或8片叶的果实感观评分最高、且酚类物质含量较高,顶端副梢留4片叶则有助于果实糖分的积累。表明陕西渭北地区"红地球"结果枝管理方法为新梢超过第3道铁丝2~3片叶进行摘心,果穗上部1个副梢留5片叶摘心,顶端1个副梢留4片叶摘心,其余副梢全部抹除。The effects of the tip topping and secondary shoot treatment on the fruit quality were studied by using 6-year-old ‘ Red Globe ’ grape. The tip shoot more than the third wire 2 to 3 leaves were topped,immediately close to the top of the ear to leave 5 pieces of leaf topping, and the top left a secondary shoot,the other secondary shoots were all erased, the results of the top of shoot leaved a different number of leaves topping. The results showed that the content of total berry weight, soluble solids, reducing sugar and total anthocyanin contents of ‘ Red Globe’ were improved by different shoot treatments compared with the control. Leaving 4 leaves and 8 leaves had higher sensory scores and phenolic substances, leaving 4 leaves also contributed to the accumulation of grape sugar. The better management method of ‘Red Globe’ was that results branch for the new shoots more than the third wire 2 to 3 leaves were topped,the upper part of the ear 1 left side leaves 5 leaves topping,the top of secondary shoots left 4 leaves topping,the rest secondary shoots were all erased in Weibei area.
