Abstract: Spring wheat, variety “Cooperation No. 3”, and winter wheat variety “Jilin”, grown in the field during the autumn in Ghangchun. Some physiological characteristics between them in fall winter period have been investigated. It was found that with the gradual falling in temperature, the growth rate, water content and respiratory rate of spring wheat and winter wheat both decreased; however, the dry weight of subterraneous part and subterraneous main stem, the percentage of bound water and the permeability of them increased as the temperature fell. The physiological characteristics of spring wheat and those of winter wheat under fall winter condition show great differences: the growth rate, water content and respiratory rate of winter wheat being lower than those of spring wheat, the dry weight of subterraneous part and main stem and the percentage of bound water of winter wheat being however, higher than those of spring wheat, the permeability of winter wheat being also more stable. Based on the experimental data, it is concluded that the physiological processes and the colloid property of protoplasm of winter wheat growing under autumn condition rapidly and strongly harden so as to adapt to unfavorable environment.
