摘　　要：为了筛选耐盐碱高油酸花生,扩展花生在盐碱地的种植面积,缓解食用油供给不足的矛盾。以NaCl:Na_(2)SO_(4):NaHCO_(3):Na_(2)CO_(3)盐碱混合溶液模拟盐碱地条件,对6个高油酸品种萌发期种子发芽率及盐害率,以及苗期幼苗干重及耐盐系数进行比较分析。结果表明:随着盐碱混合液浓度升高,花生种子发芽率以及幼苗干重明显下降。参试花生品种芽期与苗期的最适筛选浓度有所差别,芽期与苗期耐盐碱性亦并不完全一致。结合芽期和苗期指标,利用隶属函数值进行评价,确定供试品种的耐盐碱程度为‘宇花33’>‘宇花208’>‘宇花18’>‘宇花625’>‘宇花169’>‘宇花91’。100 mmol/L Na^(+)浓度为萌发期耐盐碱筛选的理想浓度,150 mmol/L Na+浓度为苗期耐盐碱筛选的最适浓度,在此条件下筛选出高度耐盐碱品种‘宇花33号’。The aims are to screen saline-alkali tolerant peanuts with high oleic acid content,expand the planting area of peanuts in saline-alkali soil,and alleviate the problem of insufficient supply on edible oil.Seed germination rate and salt damage rate during seed germination stage,and seedlings dry weight and salt tolerance coefficient during seedling stage of six peanut varieties with high oleic acid content were studied and analyzed,with a saline-alkali solution of NaCl:Na_(2)SO_(4):NaHCO_(3):Na_(2)CO_(3) simulating saline-alkali soil.The results were as follows:the germination rate of peanut seeds and dry weight of seedlings were decreased significantly,with the increase of the concentration of saline-alkali solution.The optimum screening concentration of peanut varieties at germination stage and seedling stage was different,and the saline-alkali tolerance at germination stage and seedling stage was not completely consistent.The saline-alkali tolerant of 6 peanut varieties was determined as‘YH33’>‘YH208’>‘YH18’>‘YH625’>‘YH169’>‘YH91’,evaluated by the membership function values,considering the saline-alkali tolerance both in germination and in seedling stages.The concentration of salt-alkali solution with Na^(+)100 mmol/L and 150 mmol/L might be the suitable concentration for the salt-tolerant screening in germination stage and seedling stage respectively.‘Yuhua 33’was determined as highly salt-alkali tolerant variety under this condition.
