| 摘 要： | 以黄瓜品种津春4号(Cucumis sativus cv Jinchun 4)为试材,研究了在低温胁迫下使用非激素类杭冷剂冷冻宝对其产量的影响.结果表明,2.50 g·L-1冷冻宝浓度处理的黄瓜幼苗,在低温6℃±0.2℃胁迫下,可使叶片可溶性糖的含量显著增加,丙二醛含量降低,提高幼苗的抗冷性,并具有明显的促成和增产作用.从产投比考虑,冷冻宝的最适使用浓度为2.50 g·L-1.

| Abstract: | Effects of "Lengdong-bao" on the growth of Cucumis sativus cv Jinchun 4 under low temperature stress were studied. The result showed that with the treatment of "Lengdong-bao" under the temperature 6℃±0.2℃ the content of soluble sugar in C. sativus leaves increased significantly,the contents of MDA decreased and the cold resistance improved. The optimal concentration was 2.50 g·L~(-1). |
