The results showed that the grapes with shoot-fruit ratio of 1∶ 1 had the highest soluble solid content, vitamin C content and grapevine storage nutrient. Based on the comprehensive analysis, the shoot-fruit ratio of 1∶ 1 was the optimized load for Summer Black grapes in Tai an of Shandong Province, and the yield was 1 179.37-1 288.63 kg per 667 m^2.展开更多
以6年生夏黑萄萄为试材,研究不同浓度矮壮素对夏黑葡萄果实品质的影响。结果表明,果实中矮壮素的残留浓度与施用的矮壮素浓度呈正相关性,高浓度的矮壮素能够显著减少果实的穗重、粒重、皮重、纵径、横径。低浓度(0.33 ml/L)矮壮素对于...以6年生夏黑萄萄为试材,研究不同浓度矮壮素对夏黑葡萄果实品质的影响。结果表明,果实中矮壮素的残留浓度与施用的矮壮素浓度呈正相关性,高浓度的矮壮素能够显著减少果实的穗重、粒重、皮重、纵径、横径。低浓度(0.33 ml/L)矮壮素对于果实品质的影响不稳定,中高浓度(0.5和1.0 m L/L)矮壮素对于果实品质的影响比较稳定。高浓度矮壮素对提高葡萄果实固酸比、降低总黄酮和单宁含量具有显著作用,同时能提高果胶含量和氨基酸尤其是必需氨基酸的含量,提高其营养价值。展开更多
