摘　　要：以"津春4号"黄瓜种子为试材,分别用浓度为0、50、100、500、1 000、1 500mg/L巴巴安溶液进行培养,研究了巴巴安对黄瓜种子萌发及萌发过程中某些生理指标的影响。结果表明:50～500mg/L巴巴安能促进黄瓜种子萌发及根系生长,高浓度抑制且浓度越高抑制作用越强;低浓度巴巴安处理使黄瓜根系活力增加,而高浓度处理则使其降低;50mg/L巴巴安处理使黄瓜根系在低温下电解质渗出率降低,抗低温能力增强。‘Jinchun No.4’ cucumber were treated by seed soaking with different Babaan concentrations（0,50,100,500,1000,1500mg/L）,the effect on seed germination and morphological indexes during seed germination were studied.The results showed that 50～500mg/L Babaan could effectively improve seed germination rate and its root growth,but high concentration was inhibition to it,and the higher concentration the inhibition stronger.The cucumber root vigor was enhanced in low concentration Babaan,but it reduced in high concentration Babaan.Electrolyte leakage of cucumber root was reduced by 50mg/L Babaan concentrations,and the ability of resistant low temperature.Comprehensive analysis showed that the treatment effect was best by 50mg/L Babaan concentrations.
