Therefore, the specific objectives of this study were to (1) determine and compare the chemical composition of heartwood and sapwood from graded wood of red-heart Chinese fir, (2) examine the correlations among the chemical composition of heartwood and sapwood, and (3) analyze the variation in the chemical composition of heartwood and sapwood along the directions of the trunk height and radial diameter.
The relationship between chemical composition, trunk height, and trunk radial diameter

At the micro-scale, temperature can be controlled though canopy management and trunk height
This extends the total trunk height
to a maximum of 1,485 mm, meaning that large objects can be loaded upright without folding down the rear seats.
It received the accolade thanks to its trunk height
and branches which are ideal for children to scale.
The results show that wireless sensor node deployment should take advantage of the grid-like tree planted pattern in plantations and should preferable be positioned at trunk height
or above the canopy to maximize range and improve the signal to noise ratio.
The investigated pine tree was chain-sawn and three sections (each 5 cm wide) were cut at three different heights: 1 m above the ground, in the middle of the tree-trunk and at 3/4 of the trunk height
They have been cut on the trunk height
from the meter in meter.
People can also go "glamping" at West Wood yurt village on Gibside's Cut Thorn farm Julie Tucker, events and promotions manager at Wallington, said: "Our 45ft-high Nootka Cypress evergreen has been chosen as the best tree to climb in the whole of the trust, as its trunk height
and branches make it ideal for mini adventurers."
There was no obvious relationship between surface growth stress and trunk height
. The residual growth stress was tensile for the outer part of the tree trunk and compressive for the inner part, yielding a V-shaped stress distribution.
