湿地松、火炬松木材密度变异和优树选择的研究

STUDY ON VARIATION OF WOOD DENSITY IN SLASH PINE AND LOBOLLY PINE AND SELECTION OF THEIR ELITE TREES

研究了影响湿地松、火炬松木材密度变异的主要因素；探讨了对木材密度进行综合选择的选优方法，选出湿地松，火炬松优良单株７３株。

In this paper the main factors affecting wood density variation in slash pine and loblolly pine were studied,and the method of the combined selection for wood density of slash and loblolly pine was discussed. On this basis 73 slash and loblolly pine elite trees were selected.
