Abstract
The flower production of four apple varieties have been observed grown in integrated and in ecological growing technologies during the spring of 2010. The trees produced in the last year (2009) nearly similar yields, so the effect of the technologies may causen differences in the production of flowers. According to our results, the ecological technology produced higher flower densities in the majority of variables, which was in relation with the vigor, branching and thickening of the trunks. The varieties observed displayed substantial differences in the appearance of fruiting structures of different age on the branches. This information may prove to be essential for the decisions to be made in timing and severity at the pruning operations.
Highlights
The technologies distinguished as integrated and ecological, influence the condition of trees and are expressed in the vigor and fruiting
According to Zatykó's (1980) thoughtful definition, condition means a sensitive balance between the vegetative activity and and the supply of assimilates, which is called to be optimal, if they are in harmony with each other
The present study refers to 13 year old plantation, which was held under the regime of integrated and ecological rules of technology
Summary
The technologies distinguished as integrated and ecological, influence the condition of trees and are expressed in the vigor and fruiting. On the other hand, with their exaggerated effect may induce intense vegetative activity as a sign of deleterious conditions. Among the technological moments, pruning is considered to be the most potent tool to achieve the optimal balance Gonda (2000, 2004) and Holb (2005). The present study refers to 13 year old plantation, which was held under the regime of integrated and ecological rules of technology. Four apple varieties were represented in the plantation. They were compared by adequate pruning and observed as for their production of flowers
