摘要
大气CO2浓度迅速升高引起了人们对木材碳含量变异的极大关注。尽管50%作为木材碳含量已被广泛接受,但可能产生10%的碳含量偏差。不同树种和不同部位的木材碳含量有显著的差异。木材碳含量由木质素、纤维素、抽出物等主要成分决定,挥发性成分对木材碳含量也有重要的意义。遗传因素和环境因素对木材碳含量都有间接的影响。目前,非常需要进行遗传与环境因素对木材碳含量的影响机制的研究。
The elevated CO2 and temperature have attracted much attention in wood carbon content.50%(w/w) carbon is widely promulgated as a generic value for wood,and the deviation was about 10% when it was estimated for some woods.There weresignificant differences in wood carbon content among different trees species and positions.The carbon content was determined by the main components of wood,for example lignin,cellulose and extractive et al.,but the volatile components had significant effect on the results of wood ...
