Foliar treatment of apple trees with Melongozida preparation of plant origin, mixed with trace Zn and B contributed on phonological phase of intensive growth of shoots, of increased activity of photosynthetic apparatus-sweat, breathing real and apparent photosynthesis in leaves located the apical shoots. This shows that the flow of substances is directed to the top of growing shoots. In phenophase of slow growth of shoots and fruit bud formation, fruit ripening entry, their maturation, the applied treatments influenced the photosynthetic apparatus activity, chlorophyll index and oxidase indolyl –acetic acid in leaves situated on the base out the shoots, which states that metabolic processes are focused to fruit and fruit formations–place where fruit buds are formed.
