| Abstract: | The water culture rooting experiment was based on the four parts up to down for cuttage of one-year-old seedling species of Populus nigra,which including new six clones of Xianglin,and Zhonghan-17,I-69 clone.The distribution laws and relationship of cortical salient,the number of advance adventitious roots,rooting rate of salient and root length after water culture of clones and different distinguishing parts were studied in the paper. |
