| Abstract: | In this paper, the correlativity and regression between the trunk
circumference and some biological factors such as branch number/per tree,
leaf-area/per tree, flower number/per tree, production/per tree was
studied in Su pear tree on the orchard of Chang Kang River in middle of
Shanxi Province. The results indicates that the correlativity is significant,
that, regressed progressivily, the regression model is Y=ax~2+bx+c, and
that the optimum trunk circumference is 65-75cm in this tree. |
