摘要：以广西壮族自治区范围内顶果木17个家系的实生苗为材料,探讨了顶果木优良家系和优良单株苗期选择的一些关键问题。结果表明:(1)不同家系间的苗高、地径生长量存在极显著差异。(2)通过苗高、地径两指标综合选择,选出苗期生长较快的优良家系5个,入选率为29.41%。(3)采用标准差选择法,选出155株超级苗,入选率为17.2%。
Some key problems existed in seedling selection of superior families and superior individual plant of Acrocarpus fraxinifolius Wight were studied with the seedlings of 17 families in the Guangxi Zhuang Autonomous Region. The results showed that ： （ 1 ） heights and basal diameter increments among different families were significantly different. （2） 5 superior families were selected with the characteris- tics of fast growing and the selection ratio is 29.41%. （ 3 ） 155 superior seedlings were selected by standard variance selection way with a selection ratio of 17.2%.
