%X By using self-made wooden boxes with two separated zones,the grapevine Vitis vinifera cv.Malvasia(M) grafted on rootstocks 3309C,420A and 110R,respectively,was planted,and the physiological and biochemical responses of these scion/rootstock combinations to bilateral alternative irrigation(AI) and unilateral irrigation(UI) were studied.The results showed that in treatments AI and UI,the average leaf ABA content of test scion/rootstock combinations increased by 267.5% and 394.7%,respectively,while stomatal conduction and transpiration decreased markedly.In treatment UI,the leaf SOD and CAT activities and Pro content were notably enhanced,with the greatest increment in M/110R and followed by in M/420A and M/3309C;while in treatment AI,the leaf SOD and CAT activities of test scion/rootstock combinations enhanced slightly and Pro content increased markedly.UI induced a remarkable increase of leaf relative electronic conductivity and MDA and H2O2 contents,with the highest increment in M/3309C and the lowest in M/110R.In summary,the drought resistance of different scion/rootstock combinations grapevine mainly depended on the variety of rootstock.110R had a higher drought-resistance than 420A and 3309C.Comparing with unilateral irrigation,bilateral alternative irrigation had lesser damage to grapevine,being a profitable water-saving irrigation technique.
