摘　　要：以珍珠绣线菊(Spiraea thunbergii)1年生枝条为研究对象,系统探讨了珍珠绣线菊的抗寒能力。研究结果表明:在冻融交替时期,随着温度的升高,相对电导率升高,可溶性糖和可溶性蛋白质含量下降;低温胁迫条件下,随着处理温度的降低,枝条伤害率增加,而可溶性糖含量、蛋白质含量和脯氨酸含量的升高。The material was one-year branch of Spiraea thunbergii. Its cold-resistance of Spiraea thunbergii was analysed The result showed, that during freezing and thawing alternate period with temperature going up, relative conductivity increased, content of soluble sugar and protein decreased, under lower temperature injury ratio of shoot enriched, content soluble sugar, protein and prolin increased.
