AN UNBIASED VIEW OF WOOD

 The wood of coast redwood is distinctively red. In species which display a definite difference between heartwood and sapwood the natural shade of heartwood is normally darker than that in the sapwood, and really routinely the contrast is conspicuous (see segment of yew log above).In temperate areas just one expansion ring is normally developed du

No satisfactory explanation can as still be specified for the exact mechanisms determining the formation of earlywood and latewood. Several aspects can be concerned. In conifers, at the very least, amount of growth by itself will not figure out the proportion of the two parts in the ring, for occasionally the wood of gradual progress is rather hard
