摘要: 通过对31个不同种源杉木木材管胞形态因子的数值系统测试,得出各因子的数值均值及变幅。选择造纸性能密切相关的管胞长度、长宽比、壁腔比、柔性系数等性状作为综合评估因子,根据综合坐标法,结合基本密度、生长量性状加以综合评估:湖南会同、湖南江华、福建长汀、江西全南等为相对较优良的杉木种源。

Abstract: The research examined the tracheid morphological characteristics of 31 Chinese fir provenances and got their respective average values and degrees of variation. Tracheid length, Ttacheid length-di-ameter ratio,wall thickness-lumina ratio and Lumina-diameter ratio were chosen as the indexes of synthetical selection of Chinese fir provenances as paper wood. Considering the additional basic density and volume growth the results of the comprehensive assessment wer illustrated as follows:Provenances in Huitong, Hunan Provence, Jianghua, Hunan Provence, Changtin, Fujian Provence and Quannan, Jiangxi Provence were the relatively better ones as paper wood.

Key words: CHINESE FIR PROVENANCES, TRACHEID MORPHOLOGICAL CHARACTERISTICS, COMPREHENSIVE ASSESSMENT, PAPER WOOD
