摘要
用美 5- 5等 15个杨树无性系与北京杨进行苗期对比试验 ,结果表明 :美 5- 5、美 6- 6、美 8-18、78- 2 5、美黑×欧黑均优于北京杨 ,其他无性系生长低于北京杨。
Based on contrast test of seedling stage with 15 clones of Poplar and P. beijingensis W. Y. Hsu, the results show that P. deltoides 5-5,6-6,8-18,78-25,P. deltoides Bartr × P. nigra L. are better than P. beijingensis W. Y. Hsu, other clones grow more slowly than P. beijingensis W.Y.Hsu.
