Study on the Resistance of ‘Cabernet Sauvignon’ Grapevine with Different Rootstocks to Colomerus vitis

In recent years, Colomerus vitis has caused serious economic losses due to reduced grape production in Xinjiang (northwest China). Several rootstock varieties have been reported improve the resistance of Cabernet Sauvignon vitis. This study explored influence with different rootstocks on particular, Sauvignon/Cabernet (CS/CS) was selected as control, and grafted five resistant (3309C, 1103P, 140R, SO4, 5C) employed treatment. The infestation rate injury index grapevines investigated, insect-resistant types were determined. resveratrol (Res) content, gene expression synthase (RS), activities peroxidase (POD), polyphenol oxidase (PPO), catalase (CAT), superoxide dismutase (SOD) leaves each grapevine measured. activity four enzymes content Res negatively correlated index. results revealed ability by increasing enzyme or content. 5C can be ‘Cabernet Sauvignon’ contents studied here used indexes evaluate insect rootstock–scion combinations.
