试验表明 ,七个六年生旱柳无性系在胸径、树高、材积方面有极显著和显著差异。抗虫性、稳定性及树形无性系间也存在差异。根据这些差异 ,选择出 910 0 2、910 0 5两个优良无性系供推广。
Experiments show that the seven six-year-old Salix clones have significant and significant differences in DBH, tree height and volume. Insect resistance, stability and tree clones are also different. Based on these differences, two excellent clones of 910 0 2,910 0 5 were selected for promotion.
