摘　　要：本文以典型的冬性小麦品种及春性品种为对象，利用示踪技术，通过液闪计数据方法，测定了低温胁迫下不同品种膜脂的代谢情况。根据实验的结果，从热力学的角度对低温胁迫下生物脂膜上的化学反应及扩散过程进行了分析，阐明了植株逆境下各种反应降低的原因，丰富了逆境生理研究的内容。This article is intended to use typical cold-resistant and non-cold-resistant wheat breeds as its research objects, and by way of labelled techniques and liguid scintillation counters to determine phosphatide metabolism on membranes of various breeds under cold stress. Accorging to the results of our experiment , we from the thermodynamic angle, intend to make an analysis of ahemical reaction rates and rapidity of ion diffusion on biomembranes under low temperatures and expound the cause of reduction of various reactions on plant membramce under adverse circumstances, which, therefore, might serve to enrich theconter concerning the study of adversity physiology.
