摘　　要：以8年生红宝石无核为试材,设计4个不同的单株负载量试验,研究不同单株负载量对红宝石无核果实品质的影响。结果表明,随着单株负载量的增加,果穗重、单粒重、果实纵横径均减小,果实可溶性固形物含量及果实着色度下降。综合来看,红宝石无核单株负载量控制在9穗时果实品质最佳,是最适宜单株负载量。Taking 8-year-old ruby seedless as experimental material,four different loading amounts per plant were set,the effects of different single plant loading treatments on grape quality were researched.The results showed that the weight of panicle and single fruit,the longitudinal and transverse diameters of fruits,the soluble solids in fruit and coloring degree of grape skin decreased with the increase of loading amount.In conclusion,the single plant loading of ruby seedless grape should be controlled under 9 clusters which had the optimum quality.
