摘　　要：以22个葡萄砧木品种或杂种优株为试材,对1年生盆栽植株在不同干旱胁迫时间(0、6、12、18d)条件下的叶片相对含水量、电导率、脯氨酸、丙二醛及叶绿素含量等5项生理指标进行了测定,并利用隶属函数法综合评价了各砧木的抗旱性。结果表明:根据干旱胁迫第18天时各项指标的测定结果,按照平均隶属度的大小,将砧木材料分为3种抗旱类型:对照"燕山-1"和品种"抗砧3号"属于高抗类型;‘225Ru’‘110R’‘101-14’‘5C’"河岸-2"‘6-12-1’‘6-12-4’属于中抗类型;‘1103P’‘188-08’‘00-1-10’‘00-1-5’"贝达""狗脊"‘3309’‘5BB’‘1-1-6’‘6-12-6’‘SO4’"北醇"及对照"河岸葡萄(♀)"属于低抗类型。高抗品种"抗砧3号"和中抗品种‘225Ru’‘110R’‘101-14’‘5C’可用于干旱、半干旱地区葡萄生产,中抗杂种优株‘6-12-1’‘6-12-4’可用于进一步的抗逆性(如抗寒性、耐盐性等)筛选,为新品种选育奠定基础。Taking 22 grape rootstock varieties or hybrids as materials,the relative water content（RWC）,relative conductivity,chlorophyll content,proline（Pro）and MDA of one-year-old potted plant were determined in different drought stress time（0,6,12,18days）.The drought-resistance level with subordinate function was evaluated.The results showed that the drought-resistance level of tested materials could be divided into three types according to the results of five indicators on 18 th day.The control‘Yanshan-1＇and variety‘Kangzhen 3＇belonged to high resistance;‘225Ru＇‘110R＇‘101-14＇‘5C＇,V.riparia Mcadams,‘6-12-1＇‘6-12-4＇belonged to middle resistance;‘1103P＇‘188-08＇‘00-1-5＇‘00-1-10＇‘Beta＇‘Dogridge＇‘3309＇‘5BB＇‘1-1-6＇‘6-12-6＇‘SO4＇‘Beichun＇and control V.Riparia（♀）belonged to low resistance.Variety of high resistance‘Kangzhen 3＇and middle resistance‘225Ru＇‘110R＇‘101-14＇‘5C＇could be used in grape production of arid and semi-arid areas,hybrid of middle resistance as‘6-12-1＇‘6-12-4＇could be used for further screening of adversity resistance（such as cold hardiness,salt tolerance,etc.）and laid the foundation of new variety breeding.
