摘要
以华北落叶松（Ｌａｒｉｘｐｒｉｎａｐｉａｒｕｐｐｒｅｃｈｔｉ）幼苗为材料，研究低温驯化对苗木生长发育有关的某些生理指标以及核酸转录的影响。试验结果表明，冷驯化可以提高植物的抗寒性。冷驯化后的幼苗受到－２０℃低温胁迫时，细胞质膜Ｋ＋的渗漏比对照少，光合性能提高，ＲＮＡ和可溶性蛋白质增加。
he effects of cold acclimation on some physialagical responses and
nucleic acid transcribe of Larixprinapia rupprechtii seedling were examined. The experiment
results showed that the cold acclimation increased freezing tolerance of seeding. Under the low
temperture at -20℃ condition the leakage of K + from plasma membrane was decreased, the
photosynthesis functional enhanced, the contents of RNA and Soluble protein were accumulated
by cold acctimation in seeding
