UNELE ASPECTE PRIVIND STUDIUL CREŞTERILOR GORUNETELOR (QUERCUS PETRAEAE) DIN REPUBLICA MOLDOVA

Abstract

During 2003 – 2004, there were selected and created 54 permanent sample plots for Sessile oak (Quercus petraea) of vegetative provenance, in order to study the volume growth. Researches on volume growth have been accomplished in accordance with the methodology stipulations, applied within the framework of the Chair of Dendrography under Agricultural Academy of Kiev (1984), with the methodology of B.I. Loghinov (1966) and B.B. Oghievski, A.A.Hirov (1967) researchers, using some modifications suggested by the collaborators of the laboratory, taking into account specific character of the forests of Republic of Moldova. As a result of the study, there has been established a direct impact of shoot provenance generation number on stand productivity. There has been emphasized a substantial diminution of mean growth within the framework of the same shoot provenance generation among the inferior production classes and less obvious diminution among superior production classes. Simultaneously, at the level of shoot provenance generation within the same production class there has been emphasized a substantial diminution of mean volume growth, together with the growth of shoot provenance generation.
