摘要：

研究不同转色期摘叶对‘贵人香’和‘蛇龙珠’酿酒葡萄果实品质的影响,筛选出提高2个品种果实品质的适宜摘叶时期。通过对不同时期‘贵人香’(I)和‘蛇龙珠’(C)酿酒葡萄进行摘叶处理,以未摘叶为对照,测定2种葡萄的果实可溶性固形物、总糖、可滴定酸、单宁和总酚含量等品质指标,并采用主成分分析法进行综合评价分析。在葡萄转色中期（8月17日）和完全转色后期（9月7日）2个时期进行摘叶处理,均提高了‘贵人香’和‘蛇龙珠’的可溶性总糖、可溶性固形物、总酚和糖/酸,降低了可滴定酸含量。在2个时期,‘贵人香’和‘蛇龙珠’处理组的可溶性糖含量均显著高于其对照组,分别高13.07%、22.03%、6.40%、43.38%。在完全转色后期,‘蛇龙珠’处理组的可滴定酸含量下降最显著,比对照低48.94%。‘蛇龙珠’处理组的总酚含量在2个时期均为最高(3.05、3.02 mg/g)。根据综合评价可知,在葡萄不同转色时期,摘叶对于酿酒葡萄果实品质提高由快到慢为C-9.7>I-9.7>I-8.17>C-8.17>I-CK>C-CK。在葡萄完全转色后期,摘叶处理对于‘蛇龙珠’和‘贵人香’葡萄果实品质的影响较大。

Abstract:

The paper aims to study the effect of leaf picking on fruit quality of wine grape (‘Italian Riesling’ and ‘Cabernet Gernischet’) in different color-changed stages, and screen out the period of leaf picking which is suitable for improving the quality of the two varieties. The ‘Italian Riesling’ and ‘Cabernet Gernischet’ were treated by leaf picking in different stages, and the grape fruits without leaf picking were taking as control. The total soluble solid, total soluble sugar, titratable acid, tannin and total phenol content in the two varieties were measured and analyzed by principal component analysis. The total soluble sugar, total soluble solids, total phenol, and sugar/acid were improved, and the titratable acid content was reduced in middle and later stage of full color-changed stages. In the two stages, the soluble sugar content of ‘Italian Riesling’ and ‘Cabernet Gernischet’ of the treatment group were significantly higher than those of the control group by 13.07%, 22.03%, 6.40%, and 43.38%, respectively. In later stage of full color-changed stages, the titratable acid content of the ‘Cabernet Gernischet’ treatment group decreased most significantly, 48.94% lower than that of the control group. The total phenol content in the treatment group of ‘Cabernet Gernischet’ was the highest in the two stages, which was 3.05 and 3.02 mg/g. According to the comprehensive evaluation, the score of grape fruit quality improved by leaf picking from high to low was: C-9.7>I-9.7>I-8.17>C-8.17>I-CK>C-CK. In later stage of full color-changed stages, leaf picking had great influence on fruit quality of ‘Italian Riesling’ and ‘Cabernet Gernischet’.
