摘要：对来自3个省的52个毛红椿Toona ciliata var.pubescens家系在浙江开化进行了造林试验。3年生幼林的生长结果表明,毛红椿的树高、胸径、分枝数和分枝高度等4个性状在家系间均存在极显著差异;树高、胸径、分枝数和分枝高度等4个生长性状在不同重复间表现出极显著差异;毛红椿幼林期树高和胸径2个性状具有中等以上的遗传力,而分枝数和分枝高度等2个生长性状遗传力相对较低。以树高和胸径为选择性状,选择出65号、31号、10号、9号、80号、27号、18号和19号等8个在幼林期表现较为优异的家系。
An afforestation trial for a 3-year-old young forest of Toona ciliata var.pubescens containing 52 families was conducted in Kaihua,Zhejiang Province.Four growing traits：tree height,diameter at breast height（DBH）,number of branches,and branch height were studied.Results showed significant differences （P0.01） in the four traits with different repeats.Broad heritability for tree height and DBH was above mid-level,whereas broad heritability of branch number and branch height were very low.Fast-growing families selected according to the growing traits of this young forests were No.65,No.31,No.10,No.9,No.80,No.27,No.18 and No.19.
