摘　　要：为研究落叶松对低温的生理反应 ,探讨其抗寒机制 ,以华北落叶松 (Larixprinapiam -rupprechtii)幼苗为材料 ,研究低温和ABA处理对植物可溶性糖含量、水溶性蛋白质含量、脯氨酸含量以及膜稳定性的影响。试验结果表明 :低温处理的幼苗 ,可溶性糖、水溶性蛋白质以及脯氨酸含量均增加 ,膜的稳定性增强 ;ABA处理的幼苗 ,水溶性蛋白质的含量明显增加 ,增强膜的稳定性 ,对提高幼苗可溶性糖含量和脯氨酸含量未起作用。This paper attempted to study the physiological response of larch to low temperature and to probe into the physiological mechanism for cold resistance.The seedlings of Prince Rupprecht larch were used as materials, the objective of this study is to elucidate the effect of low temperature and ABA on some physiological indicators of the plant Results showed that: after the seedlings exposed to low temperature, soluble sugar content, soluble protein content and protine content increased,membrane stability srtengthened, and ABA treatment increased the seedling′s soluble protein content, and stabitity of membrane significantly but the soluble sugar content and protine content didn′t change.Low temperature and ABA may increase the potential cold resistance of the larch seedlings
