中文摘要	【目的】筛选适合我国西北干旱、半干旱地区栽培,且抗抽干和抗旱能力强的葡萄砧木。【方法】以3309C、161-490、196-17、420mgt、 Riparia、1103P、110R、SO4、41bmgt、Rupestris du Lot 10个12年生葡萄砧木为试验材料,在冬季不进行埋土防寒条件下,通过调查各砧木萌芽率,评价不同品种抗抽干能力;生长期内对其进行干旱胁迫,测定7项生理指标,并利用隶属函数法综合评价砧木抗旱性。【结果】5种砧木未经埋土防寒,仍可萌芽,萌芽率依次为:3309C>161-49>196-17>420 mgt>Riparia。隶属函数分析表明,抗旱性强的品种为3309C、196-17、1103P、Riparia,抗旱性中等的品种为161-490 、420Mgt、110R,抗旱性弱的品种为SO4、41bmgt、Rupestris du Lot。【结论】3309C和196-17具有较强的抗抽干及抗旱性,可作为免埋土葡萄砧木使用,适合在我国西北干旱地区推广应用。
英文摘要	【Objective】The low temperature and dry air during winter and spring in the arid and semi-arid areas in Northwestern China causes the vine shriveling, which seriously affects the yield and quality of grapes and restricts the development of grape industry in this region.The resistance of grapes can be improved by selecting appropriate rootstocks with high resistance by grafting cultivation.This study aimed to selecting highly resistant grape rootstocks that were suitable for planting in this area by comparing the resistance of vines to shriveling and drought.【Methods】The experiment was carried out in the grape rootstock germplasm resources nursery of Ningxia Yuquanying Farm.12-year-old grape rootstocks were selected as experimental materials including 3309C, 161-490, 196-17, 420mgt, Riparia,1103P, 110R, SO4, 41bmgt and Rupestris du Lot.Ten kinds of rootstocks were not buried with earth or applied with any cold-proof measure in winter and the shriveling-resistance of rootstocks was evaluated by investigating the bud break rate of the annual and lateral shoots in the spring in the following year.All the rootstocks were not stressed after investigating the bud break rate with normal water and fertilizer management.The rootstocks were treated for 30 days in response to drought stress after full irrigation on August 14, 2017.The degree of drought stress was observed by measuring the predawn leaf water potential.On the 0~(th), 10~(th), 20~(th)and 30~(th)day after drought stress treatment, P_n was measured by the photosynthesizer 3051D and the functional leaves in the middle of each variety were collected and frozen in liquid nitrogen.The samples were taken back to the laboratory for determination of MDA, Pro and soluble protein contents and SOD and CAT activity.Comparison of differences in physiological indexes of grape rootstocks under drought stress was performed by different significance tests, the 30th day physiological indexes of drought stress were evaluated by the membership function method.According to the average membership value, the rootstocks were divided into 3 drought-resistance types:0.00-0.30 referred to low drought-resistance(LDR), 0.31-0.60 to moderate drought-resistance(MDR), and 0.61-0.80 to high drought-resistance(HDR).【Results】The results showed that there were only 3309C, 161-490, 196-17, 420mgt and Riparia sprouted in the spring of the following year and the bud break rates of annual vines were 79.85%, 57.35%, 64.02%, 47.93% and 24.8%, respectively, and the bud break rates of the lateral vines were 72.94%, 75%, 61.87%, 52.95% and 50%, respectively.The bud break rate of other rootstocks was 0 and the annual vines were shriveled and dead.Therefore, the order of the resistance of vines to shriveling according to the bud break rates of rootstocks was 3309C >161-490 >196-17 >420mgt >Riparia, 1103P, 110R, SO4, 41bmgt and Rupestris du Lot.After drought stress, the leaf water potential and Pn decreased, MDA and Pro contents, and the activity of SOD and CAT increased.Except for Rupestris du Lot, soluble protein contents in other treatments increased with the enhancement of drought stress.The leaf water potentials of 1103P, 3309C and Riparia were higher than other types and higher water retention capacity was observed at 30th day after drought stress.
