鲁西毛白杨优良无性系的选育

Selective Breeding on the Superior Clone of Chinese White Poplar in Western Shandong

将山东省林木良种普查选出的鲁西毛白扬优树无性繁殖,建立起无性系测定林,进行代中选优。经过10年的观测研究,结果表明:82033、82032号的材积生长量与对照(易县毛白杨)差异显著,分别超过对照29.1％和24.3％,且主要形质指标优良,抗病能力较强,可以作为鲁西地区的推广良种。

The most splendid tree of Chinese white poplar in western Shandong selected from forest high-quality seedling census in Shandong is asexually reproduced. Thus, a clonal mensuration forest is estabished from which more higher-quality seedling is selected from fine breed. By 10 years observation and study, it shows that the difference is distinct between 82033 and 82032 in material and solid growth-quantity and comparison (Chinese white poplar of Yi County) .Their super- comparisons are respectively 29.1% and 24.3%. In addition, their primary form quality targets are fine and they are stronger in ability to disease-resistance. So they can be extended as high-quality seedling in western Shandong.
