摘要： 为了选育出适合苗圃培育的紫薇无性系品种，以泰山林业科学研究院初选的10个速生性状比较明显的紫薇无性系扦插苗为材料，调查分析各无性系间幼苗苗高、50 cm地径的年生长量。结果表明，‘大华6号’苗高平均年生长量最大(124.3714 cm)，地径平均年生长量最大(1.0514 cm)；‘岱2号’苗高和地径平均年生长量次之，这2个无性系是具有明显速生性状的紫薇无性系品种。

Abstract: To obtain Lagerstroemia indica clone varieties for nursery foster, ten kinds of cutting clone varieties selected by Taishan Forestry Academe were used as materials for surveying the annual growths of different varieties’ height of seedlings and 50 centimeter ground diameters. The result of the observation showed that Lagerstroemia indica ‘Dahua 6’ had the most annual (124.3714 cm) increment and the most ground diameter (1.0514 cm) increment, ‘Dai2’ had the second most annual and ground diameter increment. These two were the fast-growing varieties obviously.
