| 摘 要： | 对从美国引进的6 a生柳叶栎9个种源的生长性状进行测定分析,结果表明不同种源的树高、胸径、分枝数、分枝角和枝下高均存在显著差异,而冠幅并未达到显著差异水平.生长最好的19号种源的平均树高、胸径和冠幅分剐为2.4 m、6 cm、1.64 m,是最差的22号种源的1.14倍、1.3倍和1.12倍.依据多性状选择指数,初步筛选出19号、18号和23号等3个生长表现优良的种源.

| Abstract: | The growth indexes of nine provenances of six-year-old Quercus phellos tree introduced from the United State were measured in this study.The results showed that the significant differences on tree height,DBH,number of branch,angle of branch and clean length were observed between provenances of Quercus phellos except the crown width.The average height,DBH and crown width of number 19 provenance(the best provenance in this study) was 2.4m,6cm and 1.64m,respectively,and it was respectively 1.14,1.3 and 1.12 times of number 22 provenance(the worst provenance in this experiment).By the muti-characteristic selection method,the number 19,23 and 18 provenances were preliminarily considered superior provenances. |
