Rezumat

The investigation have shown considerable infl uence in the fi rst period of vegetation of Melangozidă – O on the vegetative growth and fruit formation, content of glucoses and dry substance in the leafs. The enzymatic activity is intensifi ed in the leafs of fructiferous formations without fruits in the period of fruit maturing, which could create favorable metabolic conditions for the processes of fl oral induction. The unfavorable edaphic and atmospheric conditions for the activity of the metabolic processes, the growth of sprouts slowed down sooner, and the fruits, having a inappropriate size compared to viable ones, mostly fell down before the harvest, leading to negative impact for the fruit production.
