Abstract
The search for alternative sources of fuel has modified traditional models of forest production, with new concepts emerging and with new problems for production. Therefore, the biomass and carbon in stands of three Eucalyptus urophylla x E. grandis hybrid clones at two densely planted spacings were quantified. The study was implemented in a completely casualized design, with hybrid clones AEC 1528, I144 and GG100 at spacings of 3.0 m x 0.5 m and 3.0 m x 1.0 m, with 3 replications and 50 plants per plot. After 33 months the trees were harvested for biomass and carbon quantification. The hybrids I144 and GG100 yielded higher productions of biomass and carbon of stemwood and stembark. The smaller spacing increased the production of biomass in all evaluated compartments but did not change the carbon concentration.
寻找替代燃料来源改变了传统的森林生产模式，出现了新的概念和新的生产问题。为此，对3个尾巨桉(Eucalyptus urophylla x E. grandis)杂交无性系在2个密植间距下的林分生物量和碳进行了定量分析。试验采用完全随机化设计，以杂交无性系AEC 1528、I144和GG100为试验材料，株距分别为3.0 m × 0.5 m和3.0 m × 1.0 m, 3个重复，每亩50株。33个月后，采伐树木进行生物量和碳量化。杂交品种I144和GG100的茎材和主干生物量和碳产量均较高。较小的间距增加了所有评价室的生物量产量，但没有改变碳浓度。
期刊介绍：
Scientia Forestalis is a scientific publication of the IPEF – Institute of Forest Research and Studies, founded in 1968, as a nonprofit institution, in agreement with the LCF – Department of Forest Sciences of the ESALQ – Luiz de Queiroz College of Agriculture of the USP – São Paulo University. Scientia Forestalis, affiliated to the ABEC – Brazilian Association of Scientific Publishers, publishes four issues per year of original papers related to the several fields of the Forest Sciences.
The Editorial Board is composed by the Editor, the Scientific Editors (evaluating the manuscript), and the Associated Editors (helping on the decision of acceptation or not of the manuscript, analyzed by the Peer-Reviewers.
