Abstract: urvival rate, chlorophyll, dissoluble sugar and bound of rice seedling of different resistant variety were studied in terms of their strain value, velocity and acceleration.The results indicated that only downward constant strain acceleration existed in the survival rate and chlorophyll change,while both downward and upward varying strain acceleration were found in dissolvable sugar and bound water. It could be concluded that the strain pattern under low temperature was different for morphology (survival rate and chlorophyll)and physiology (sugar and water).
