| 摘 要： | 林木株间变异和株内变异是木材的两个主要变异来源,由于木材性状具有较强的遗传性以及育林措施对木材的可塑性,人们可以培育出材质优异的木材,然而因变异的存在,在如何充分利用木材时却遇到了许多困难。林学家的一个主要目的就是在充分掌握木材变异规律的基础上,采用有效方法提高材质的均匀性。

| Abstract: | There were highly significant variations within and among trees in plantation of Masson Pine for latewood tracheid length. The tree, ring and tree x ring interaction effects accounted for 13%, 39% and 9% of total variation respectively, and the radial effects were small. Variations from the pith to the bark and from the base to the top complied with the general rules of tracheid length in conifer. Theoretically, the combination of ten trees and one radius was a better sampling strategy which would estimate effectively the wood properties of a population or a strain. The age of transition from juvenile to mature wood for tracheid length of plantation was about 12 years and was more than one of natural stands in the same geographical region. The percentage of juvenile wood decreased dramatically with tree ages and varied with different individuals. |
