枫香半同胞家系早期选择的研究

为筛选适应湖北及相似环境条件生长的枫香优良家系,以132个枫香半同胞家系为实验材料,以7年生的胸径、树高、冠幅、分枝角度等为指标进行综合评价。发现枫香半同胞家系间差异较大,材积、胸径、树高、冠幅、分枝角度受中度的遗传控制。表明枫香半同胞家系可以进行优良家系选择,通过筛选得到43个生长表现较好的优良家系。

Studies on Early Selection for Half sib Families of Liquidambar formosana

Abstracts:For the selection of excellent Liquidambar formosana families that adapting to Hubei and other similar environment,132 7-year-old half sib families were used as experimental materials,a comprehensive evaluation was carried out with DBH,tree height,crown width and branch angle and other indications.There were significant differences in Liquidambar formosana half sibling families.Volume,DBH,tree height,crown width and branch angle were by moderate genetic control.43 excellent Liquidambar formosana families of good performance were selected.
