摘　　要：以采自黑龙江省尚志市帽儿山地区和五大连池老黑山地区的鹿蹄草为试材,分析测定了自然越冬过程中鹿蹄草内源激素含量的变化。结果表明:在自然越冬过程中,鹿蹄草叶片中的脱落酸(ABA)呈先上升后下降的趋势,最高值出现在12月份或1月份;吲哚乙酸(IAA)呈现小幅度下降趋势,整体变化趋势并不明显,因此与鹿蹄草抗寒性无显著相关性;赤霉素(GA)则一直呈现均匀的梯度下降趋势;ABA/GA比值也呈先上升后下降趋势,但上升幅度远远大于降低幅度,与鹿蹄草的抗寒性呈正相关。Taking the Pyrola rotundifolia that collected from Maoer Mountain in Shangzhi of Heilongjiang province and the area of Laoheishan in Wudalianchi as test materials,the changes of endogenous hormones in cold resistance determination were analyzed and measured.The results showed that ABA presented first rose and then fell,the highest value occured in December or January.IAA showed small decline,the overall trend was not evident,and cold resistance of Pyrola rotundifolia had no significant correlation.GA had been uniform rendering of the gradient on the decline.Ratio of ABA and GA had taken a first rise after a downward trend,but the increase was far greater than the lower range.
