End checking of a pine timber.

A compression wood reaction occurs in conifers of the lower side of the trunk while tension wood occurs on the upper side of the leaning trunk. Compression wood has a little amount of cellulose when compared to tension wood cellulose.

Tension wood is quite common in gymnosperms while compression wood in angiosperms. Compression wood is quite common in conifers like pines while tension wood Estimated Reading Time: 3 mins.

in fact,in tension and works to upright the leaning bushlopping.barn wood may also be formed in response to wind or similar bending forces; in these cases the wood is stiffened against the force being applied to the bushlopping.bary, tension wood may be formed in response to light--bending the tree toward the light.

Mar 13, A decided lean or unbalanced crown will affect wood strength - compression in softwoods, tension in hardwoods. If a tree falls on a large rock or stump, it may break, or rebound. Cut any brush that may affect your work, and always create an escape path behind the direction of fall, at a degree bushlopping.barted Reading Tension compression tree leaning 7 mins. describes general features of tension wood and compression wood, with indications of some of the common types of variation.

1. Anatomical and chemical characteristics of tension wood. Tension wood is formed on the upper side of leaning angiosperm stems and creates tensile force to pull the stem upward (Fig. 1a,b). Jun 15, What is Tension Wood?

Tension wood is usually formed in dicots on the upper side of the trunk which is leaning or bent. Tension wood contains more cellulose than compression wood therefore it is very strong in tension and can easily resist leaning or bending. Hardwoods like oaks form tension wood in them on the upper side of the branch.
