THE INFLUENCE OF PRE-HARVEST TREATMENTS ON FRUITS QUALITY OF APPLE CULTIVARS (MALUS DOMESTICA BORKH.)

Apples fruit quality is mainly influenced by biotic and abiotic factors. Various possible pomological approaches are able to improve market value. Among these, techniques of bagging summer pruning have become an integral part practises in many countries, because it a safe eco-friendly technique protect fruits from multiple stresses, preserving or improving the overall quality. The consists essentially enclosing young cardboard bag. Isolating external environment protects during development mechanical damage, especially regions where prone attacks fungi, bacteria, insects even birds. expected increasing skin color comparison non-bagged can therefore correspond either reduction increase greater homogeneity itself.
