马尾松家系木材管胞形态特征的年龄变异OACSTPCD
Age Variation of Wood Tracheid Morphology of Pinus massoniana Families
利用马尾松初级种子园29个半同胞家系,研究木材管胞的年龄变异.结果表明:马尾松的管胞宽度、管胞长度、管胞长宽比、管胞壁厚、壁腔比、柔性系数、刚性系数等7个指标在同年龄早晚材间均存在显著差异和极显著差异；管胞腔直径在不同年龄间差异不显著,在早晚材间差异极显著；管胞形态基本呈现出幼龄材品质优于中龄材,早材优于晚材的规律.用管胞长宽比、壁腔比和柔性系数3个指标评价马尾松的造纸制桨性能,均属优良的制浆用材；胸径年增长量与管胞形态呈显著或极显著相关,可作为…查看全部>>
The age variation of the Pinus massoniana wood tracheid was studied by analyzing 29 half-sib families of this tree species in primary seed orchard. The results showed that there were significant or extremely significant differences in the 7 indexes including tracheid width, length, length/width ratio, tracheid wall thickness, tracheid wall thickness / lumen ratio, tenderness coefficient, and rigidity coefficient of the tracheid between the early wood and the…查看全部>>
