Abstract

: This study aimed to evaluate the productive performance and physicochemical traits of wine grape cultivars (Cabernet Sauvignon, Syrah, Cabernet Franc, Merlot, and Sauvignon Blanc) grafted on two different rootstocks (IAC 766 Campinas, and 106-8 Mgt) under subtropical conditions. The productive components (number of bunches, production per vine, yield, number of berries per bunch, fresh mass, length, and width of berries) and the grape must physicochemical composition (pH, titratable acidity, soluble solids, and maturation index) were determined after four consecutive harvest seasons. Results from analysis of variance and principal component analysis showed that Cabernet Franc and Syrah were generally more productive than the other ones. In addition to that, Cabernet Sauvignon presented the lowest production and the smallest grape berries of all. With regards to rootstocks, IAC 766 induced higher scions yield than 106-8 Mgt; besides that, IAC 766 had greater affinity with Cabernet Franc and Merlot, which was observed by the increase in the number of bunches per vine, larger and heavier bunches, as well as higher soluble solids content and pH value than the ones in 106-8 Mgt. Furthermore, IAC 766 also induced higher soluble solids content and pH value for Cabernet Sauvignon. Results showed similar effects for Syrah and Sauvignon Blanc, regardless of the rootstocks.

亚热带条件下不同砧木嫁接酿酒葡萄的产量性能和品质

摘要:本研究旨在评价亚热带条件下酿酒葡萄品种(赤霞珠、西拉、品丽珠、梅洛和白苏维翁)嫁接在不同砧木(IAC 766 Campinas和106-8 Mgt)上的生产性能和理化性状。在连续四个收获季节后，确定生产成分(串数、单株产量、产量、每串浆果数、新鲜质量、浆果长度和宽度)和葡萄必须的物理化学成分(pH值、可滴定酸度、可溶性固形物和成熟指数)。方差分析和主成分分析结果表明，品丽珠和西拉的产量普遍高于其他品种。除此之外，赤霞珠的产量最低，葡萄果实也最小。砧木方面，IAC 766诱导的接穗产量高于106-8管理;此外，IAC 766与品丽珠和梅洛的亲合力更强，表现为单株串数增加、串长、串重，可溶性固形物含量和pH值均高于106 ~ 8mt。此外，IAC 766还能提高赤霞珠的可溶性固形物含量和pH值。结果表明，无论砧木如何，西拉和长相思的效果相似。
