樟树家系试验林生长调查

Growth of Test Sites for Families of Cinnamomum camphora

通过对6个试验点2年生樟树55个家系试验林进行的调查分析,结果表明:樟树各家系间生长性状差异显著,家系×地点交互作用达到极显著水平,家系选择潜力较大。市郊林场系百日苗造林,树高生长种内变动程度较大,个体生长差异更明显;其余试验点的家系生长差异变化程度为:南平校区>德化基地>松溪林场>永林公司>永安林场;不同试验点樟树家系的地理变异模式不同;根据家系的生长和适应性表现,选出了生长优良且具较高稳定性的10个家系,同时筛选出30株优良单株。

Fifty-five families of 2-year-old Cinnamomum camphorain 6experimental sites were investigated.Result shows that there are significant differences in the growth traits among the selection potentiac of families of C.camphora;the families of C.camphorais larger.Result shows that there are significant differences in the growth traits among the families of C.camphora;the degree of variation of the growth of the rest of the experimental sites is as follows：Nanping Campus〉 Dehua Base〉 Songxi Forest Farm〉 Yongan Forest Farm;according to the growth and adaptability of the family,the families with optimal growth ＆ high stability were selected,and 30 strains of fine plants were also selected at the same time.
