It is indisputable that cambium maturity contributes to the basic density of wood. It is shown that in the case of two independent Scots pine materials collected from Eastern Finland, the basic density depends solely on cambium age, while distance from the tree pith makes no contribution at all. It is also shown that the basic density is independent of(More)
The inverse of the relative increment rate of size is proposed as a measure of the maturity of a forest tree. The heartwood content within bole cross sections is modeled semiempirically using asymptotic fitting. It is shown that the present proposal for a definition of maturity statistically explains heartwood content far better than age or size. The(More)
