该文用形态学、叶片微观结构电镜扫描和ＰＥＲ，ＥＳＴ，ＧＯＴ３种同工酶的分析方法，对３个黑、白杨派间杂交组合的亲本与杂种进行了研究．结果表明：黑白杨派间杂种都兼具父母本特征，且变异类型丰富．因此，培育出具备黑杨、白杨优良性状的黑白杨杂种无性系大有希望．
This paper studied the parents and hybrids of three black and white poplar crosses with morphology, leaf microstructure scanning electron microscopy (SEM) and PER, EST and GOT isozymes. The results showed that both black-white and poplar inter-genus hybrids had the characteristics of parents and the types of variation were abundant. Therefore, cultivating black and white poplar clones with excellent traits of poplar and poplar have great hope.
