Abstract: This study aims to screen rootstocks for‘Cabernet Sauvignon’grapevine, and provide certain basis for scientific application of rootstocks. Taking‘Cabernet Sauvignon’grapevine as test materials, the authors grafted the grapevine on four kinds of rootstocks:‘SO4’,‘5BB’,‘3309C’,‘101-14’. The survival rate, phonological period, growth of fresh treetop, leaf area, chlorophyll content, spike weight, spike size, grain weight, grain size, soluble solids content, reducing sugar content and titratable acid content were analyzed. The results showed that rootstocks had certain effect on the growth phenological phases of‘Cabernet Sauvignon’ grapevine. The survival rate, the winter survival rate, the germination rate, the leaf area and chlorophyll content of‘Cabernet Sauvignon/3309 (CS/3309C)’were relatively high and the new shoots were stronger. Different scion/rootstock combinations all had‘feet’phenomenon. The fruit appearance quality (spike and berry) of various combinations was improved, and that of CS/3309C was better. The total soluble solid content and reducing sugar content of CS/3309C were higher than that of other combinations.‘SO4’delayed the maturation o‘f Cabernet Sauvignon’grapevine. On the whole,‘3309C’improved the growth and fruit quality of ‘Cabernet Sauvignon’grapevine.
