中国柏木属(Cupressus L.)植物的petG-trnP序列分析及其系统学意义

open access: yes四川大学学报. 自然科学版, 2005
对中国柏科(Cupressaceae)柏木属(CupressusL.)5个种及扁柏属4个种的cpDNA非编码区petG-trnP序列进行了分析,其片段的长度范围在417bp479bp之间.以侧柏(Platy-cladus orientalis)作为功能性外类群,运用PAUP*和MEGA软件分别对其进行聚类分析,应用最大似然法得到一棵最优系统树,其-Ln=2232.47.结果表明:用petG-trnP序列来分析柏木属和扁柏属的系统发育关系是可行的;中国柏木属植物是一个单系类群 ...

Effects of selected joint parameters on tensile strength of steel bolt-nut connections in Cupressus funebris wood

open access: yesBioResources, 2019
The influences of various factors on the tensile strength loading caused by steel bolt-nut connections on Cupressus funebris wood components in directions perpendicular and parallel to the grain were studied. The focus was the interference fit parameter between the nut and the pre-drilling hole, the nut embedded depth, and the embedded nut diameter ...

Global Warming Regulates the Contraction and Expansion of the Adaptive Distribution of Cupressus funebris Forests in China

open access: yesForests
Cupressus funebris forests grow relatively fast and have a strong natural regeneration ability, showing great potential in carbon sequestration. Global warming has already had a significant impact on its distribution pattern. This study used the Maximum Entropy Model (MaxEnt) and the distribution data of Cupressus funebris communities to explore the ...
