It is known that the growth rate of a tree, respectively, a stand, during its life differs from one period of life to another. Thus, the growth rate is more accelerated at the beginning of life, so that, achieving the peak of growth in volume, this rate gradually decreases, becoming more and more weak in old age, until the tree stand passes into a state of decrepitude. This variation in the process of accumulation of wood biomass makes the economic efficiency of the tree, respectively, the stand, which varies depending on the development phase, i.e. its age. This increase in volume, usually expressed by the current annual growth of the tree, respectively, the stand at the level of measurement unit and transferred to total yield, ultimately defines its economic efficiency, which in turn varies according to the amplitude of the variation of the growth index. In this context, the purpose of this paper was to evaluate the diameter increments of sessile oak stands (Quercus petraea Liebl.) of vegetative origin from shoots in the Republic of Moldova in relation to the yield class, age and generation originating from shoots, as well as in relation to the composition and consistency of the stand at the level of physical-geographical areas and phytoclimatic levels. |
