OBJECTIVE FORESTRY

Detailed explanation-1: -In an annual ring, the light-coloured part is known as early wood or spring wood. It is formed when the cambium is active. It consists of more number of xylary elements with wider cavities. This wood is lighter in colour with low densities.

Detailed explanation-2: -growth ring, in a cross section of the stem of a woody plant, the increment of wood added during a single growth period. In temperate regions the growth period is usually one year, in which case the growth ring may be called an “annual ring.” In tropical regions, growth rings may not be discernible or are not annual.

Detailed explanation-3: -These xylem layers give us the annual rings. As spring begins, new cells are added quickly, and the tree increases in diameter. In a cross section of a stump, this growth appears as a wide, light-colored band called early wood or springwood.

Detailed explanation-4: -These rings can tell us how old the tree is, and what the weather was like during each year of the tree’s life. The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall.
