Abstract: Based on the field- measured data of the base diameter,diameter at 50 cm from the bottom,total height,height from the base to the first branch,substations,branches in each substation,and crown diameters of man-sowed A.scholaris,and employing double analysis,variance analysis,and compare means methods,this paper studied the growth status of the tree in three areas with different environmental conditions.The results indicated that A.scholaris growth had highly positive correlations with mean annual temperature,mean temperature of the coldest month,and relative humidity,but a highly negative correlation with altitude.
