| Abstract: | The investigated results show that there exists obviously a “slow-fast-slow” growth rhythm in height growth process of Ulmus elongata. Then this growth process are simulated and divided into three stages by Logistic equation. There is a positive correlation between rate of height gr owth and rate of leaf increment. Using relation analysis method, it has been re vealed that the temperature is the essential environmental factor affecting the seedling growth. |
