摘要： 为探讨紫薇抗寒性能力之间的差异，以7个紫薇品种为实验材料，采用电导法、叶绿素荧光法和非损伤微测计数法对紫薇进行抗寒性鉴定，并与田间观察实验对比，研究了低温对紫薇抗寒性指标的影响及不同鉴定方法与抗寒性之间的关系。

Abstract: In order to analyze the differences on chilling tolerance of different Lagerstroemia indica L. varieties, the conductometry method , chlorophyll fluorescence method and NMT method were employed to measure various chilling tolerance parameters and their variation regularities in seven Lagerstroemia indica L.varieties. Through comparing with the field observation to research the effect of low temperature on chilling tolerance parameters of Lagerstroemia indica L. seedlings and the relationship between different appraisal methods and the chilling tolerance of different Lagerstroemia indica L.varieties.
