Studiul creșterilor în diametru a stejăretelor de stejar pedunculat de provenienţă vegetativă (lăstari) din Republica Moldova

Abstract

In the context of the concerns regarding the better management of the fundamental natural oaks grove forests of the Republic of Moldova in the future, this paper tries a fundamental approach on assessing the growth in diameter of pedunculate oak stands originating from vegetative regeneration by shoots in the Republic of Moldova. The stands under study are between 65-100 years old, belong to I-V generation of shoot origin, are lo-cated on three phytoclimatic levels and fall into yield classes 3-5. By their composition the stands are both pure and mixed and have a normal consistency (over 0.6). The maximum current growth index, the average growth index and the age at which the curve of the current growth index intersects with the average growth index, which means the peak of growth and economic efficiency of the stand, were evaluated and analyzed. The data did not show a significant difference between growth indices in pure and mixed stands, nor was there a significant variation at the level of physicogeographical areas or phytoclimatic levels. On the other hand, there is a correlation of the growth indices with the yield class of the stand and with the generation of shoot origin The research was carried out in the context of the implementation of the provisions of the development strategy for the forestry sector regarding the improvement, restoration, conservation and ensuring the sustainable development of the national forest estate
