摘　　要：以‘常规伽师瓜’‘绿肉伽师瓜’和‘杂交伽师瓜’为试材,在芽苗期设定0、25、50、75、100、125 mmol·L^(-1)共6种盐浓度,探究盐浓度对伽师瓜种子萌发的影响,鉴定品种间的耐盐性,以期快速筛选耐盐型伽师瓜品种。结果表明:盐浓度、品种及品种和盐浓度的交互作用极显著影响发芽率、发芽势、发芽指数、活力指数、根长、芽长及鲜质量。相同盐胁迫下,不同伽师瓜种子萌发指标存在较大差异。利用隶属函数法建立综合评价体系,发现常规伽师瓜的综合得分值为0.898,为耐盐型品种,绿肉伽师瓜为盐敏感型品种。推荐常规伽师瓜种植在中轻度盐渍化土地,有利于盐渍化土地的利用。Taking‘Canggui Jiashi Melon’‘Lyurou Jiashi Melon’‘Zajiao Jiashi Melon’as test materials,six salt concerntrations of 0,25,50,75,100,125 mmol?L^(-1)NaCl were set at bud seedling stage.The effect of salt concentration on the germination period of Jiashi melon was studied,and the subordinate function was used to evaluate the salt tolerance among cultivars,in order to screen salt tolerance Jiashi melon cultivars quickly.The results showed that the interaction of salt concentration,cultivar,cultivar and salt concentration significantly affected germination rate,germination potential,germination index,vigor index,root length,bud length and fresh weight.Under the same salt stress,there were differences in the seed germination indexes of different Jiashi melons.The comprehensive evaluation system was established by using the affiliation function method,and it was found that the comprehensive score value of conventional‘Changgui Jiashi Melon’cultivar was 0.898,which was more salt tolerant and the‘Lyurou Jiashi Melon’was salt sensitive.‘Changgui Jiashi Melon’was more suitable for planting in moderate to light saline land.
