摘要:
 采用伐倒木取样的方法,对帽儿山、凉水、加格达奇3个地点31年生长白落叶松种源的生长性状、基本密度以及化学成分进行测定分析,运用spass18.0及DPS V14.10软件估算了各性状的变异系数,并进行方差分析、多重比较、主成分分析、稳定性分析以及综合评价,以筛选出优良的纸浆材种源。结果表明,3个地点种源间基本密度差异极显著,其他性状在3个地点的种源间差异性不完全一致。材积的变异系数最大,为20.43%,其他性状的变异系数均<10%。多重比较和单地点主成分分析筛选出单地点优良种源,稳定性分析及地点间主成分分析筛选出多地点优良种源。整合几种分析方法筛选出的优良种源,最终选择鸡西、穆棱、白刀山这3个种源为优良纸浆材种源。3个优良种源的材积、基本密度、纤维素含量的平均值分别为0.310 m3、0.442 g/cm3、47.032%,其中材积和基本密度增产效果明显,分别超过总平均值2.99%、1.84%。
Abstract:
 The growth character, wood basic density and chemical constituents were analyzed for the superior pulpwood provenance selection in 31-year-old Larix olgensis provenances located in Maoershan, Liangshui and Jiagedaqi. After the test of felled-wood samples collected from these three sites,we analyzed the data by spss 18.0 and DPS V14.10 to estimate the variation coefficients,and to conduct variance analysis,multiple comparison,principal component analysis,stability analysi and comprehensive evaluation. The results showed that there were significant differences in wood basic density among provenances in all three sites while other characters were not the same. The variation coefficient of timer was the most (20.43%) among all characters,while the other characters were less than 10%. The superior provenances in single-site were selected by multiple comparison and principal component analysis and that in three sites were selected by stability analysis and component analysis in different sites. Finally,three provenances (Jixi,Muling, Baidaoshan) were selected as the superior pulpwood provenances by mentioned analysis methods. The average timber volume, basic density and cellulose content of these three provenances were 0.310 m3,0.442 g/cm3 and 47.032% respectively,especially the timber volume and basic density increasing effect was obvious,they were 2.99% and 1.84% more than average respectively.
