Abstract


In Romania it is necessary a sustained effort to extend the forest areas through artificial regeneration. The purpose of this study is to show the correlation between the heights and diameters of Quercus petraea trees from seed reserves and their seed production. They were chosen 80 trees situated in four Quercus petraea seed reserves of Cluj County. The trees selected were located at a distance of 30 meters from each other. It has been found that the two measured variables (core diameter and trees height) are direct positive correlated, in the sense that increasing the value of a variable and thus leads to an increase in the other. Choosing trees with special qualities have great importance when it comes to transmitting genetic gain new generations. Comprehensive analysis of stationary and vegetation characteristics result in reproductive material with significant values as seeds quality and adaptability.
