Effects of different root stocks on the growth and fruit quality of ‘Zuijinxiang' grape
In order to understand the influence of different root stocks on grape growth and fruit quality, ‘Zuijinxiang' grape was grafted onto three root stock varieties, ‘Beta', ‘Huanjia 8', and ‘SO4' and its performance was investigated. The results showed that root stock had a significant influence on the growth, yield, and fruit quality of ‘Zuijinxiang' grape. Among three scion/rootstock combinations, Zuijinxiang/Huajia8 showed no obvious overgrowth above or below the graft union and had the largest leaf area, highest chlorophyll content, and highest yield. Fruits from these grapes contained the highest soluble solid content and the lowest titratable acid content. The performance of Zuijinxiang/SO4 was poor. Zuijinxiang/Beta showed obvious overgrowth above the graft union, weak growth vigor, lowest yield and the fruit quality was the worst with the highest titratable acid content. The order for the growth and fruit quality of the three scion/rootstock combinations from the best to the worst was Zuijinxiang/Huajia8Zuijinxiang/SO4Zuijinxiang/Beta.
