摘　　要：试验对34个黄瓜品种发芽期的抗土壤盐渍化主要因子NaCl和Ca(NO3)2·4H2O协迫差异进行了研究。根据黄瓜在CK、4、10、16g/LNaCl和CK、15、20、25g/LCa(NO3)2·4H2O)胁迫下12、24h、2、4、6d相对发芽率、5d芽长、8、12d芽后死亡率等指标的生物统计结果选择出抗NaCl胁迫的长春密刺>津研506>中农七号>津杂三号>津研四号>鲁黄瓜九号和抗Ca(NO3)2·4H2O胁迫的长春密刺>中农1101>津春四号>津春三号>北京401>早春八号>兴丰88-8等抗盐品种及抗盐能力顺序。The main salts which cause salinization were NaCl in coastal area and Ca(NO 3) 2·4H 2O in protected soil The salinity-resistant ablility of 34 cucumber cultivars(Cucumis sativus L )was tested separately under the stresses of both NaCl and Ca(NO 3) 2·4H 2O during their germination The cucumber cultivars were treated with NaCl at CK,4,10,16g/L and Ca(NO 3) 2·4H 2O CK,15,20,25g/L The investigating items were 12 and 24-hour germination percentage to CK(GPC)for NaCl treatments and 2,4-day germination percentage to CK,5-day bud lengths,8,12-day bud death percentages for Ca(NO 3) 2·4H 2O treatments etc There were 6 salinity resistant cultivars to be selected to NaCl stress and 7 to Ca(NO 3) 2·4H 2O stress according to the data
