摘　　要： 为研究不同留果量对赤霞珠葡萄(Cabernet Sauvignon)生产势的影响,以五年生赤霞珠葡萄为试验材料,对其进行每延长米架面分别留果20、30、40、50穗的处理。结果表明,赤霞珠葡萄单位架面不同留果量对坐果率、叶面积指数、光合速率、产量和品质都有一定的影响。随单位架面留果量的增加,产量上升,坐果率明显降低;比叶重、叶厚和叶绿素含量呈下降趋势,但差异不显著。 The effects of fruit density on growth potential of grape Cabernet Sauvignon were studied using 5-year-old cabernet sauvignon plant as material.The fruit density was kept as 20,30,40 spike per running meter of grape shelf.The results showed that the fruit density had certain effects on the fruit setting rate,leaf area index,photosynthetic rate,yield and quality of grape.With the increase of fruit density,the yield of grape was increased;fruit setting rate was significantly decreased;and specific leaf weight,leaf thickness and chlorophyll content was decreased with no significant difference.
