不同杨树新品系生长量的方差分析

Variance Analysis on Growth of Various New Poplar Cultivars

以我国引进和培育的６个杨树品系（Ａ－长绿Ｉ－７２、中潜６＃、中石２＃，中嘉８＃、中新４＃）为材料，对它们在我国南方生态条件下的生长特性进行方差分析，其结果表明，各品系间高生长量的差异达到极显著和显著水平．杨树品系“Ａ－长绿”的高生长量最大．

Using various poplar(A Changlu,I 72,Zhongqian 6,Zhongshi 2,Zhongjia 8 and ZhongXing 4)as experimental materials,we studied the growth characteristics in the south of China.By variance analysis,the growth differences among the cultivars are significant.“A Changlu” growes the highest among the six cultivars.
