| Abstract: | Using man-investigation data of 300 107 new varieties populus to study the relationship between crown size and tree diameter at breast height of 107 new variety populus.It indicates that the two characters have quite closely linear relationship,the correlation coefficient is 0.9399.A linear model were Y=-0.819+0.238X. |
