The behavior of some apple varieties cultivated in superintensive system, in Fălticeni fruit growing basin

Abstract

The purpose of this work is to follow the production of new apple varieties, grafted on a rootstock of low vigor (M9) cultivated in an area devoted to this species, the Fălticeni orchard basin. The work starts from the characterization of the natural environment in which the orchard is located, taking into account measurements regarding the growth vigor of the trees, the resistance to the limiting factors of production, the phenophases of the fruiting organs. However, the most important thing at the end of a fruit growing year is the economic yield given by the plantation, therefore it is important to determine the annual production obtained for each variety. For the observed year, production was satisfactory for all varieties, varying between 42.74 t/ha for the ‘Golden D. Reinders’ variety and 58.67 t/ha for the ‘Szampion’ variety. Although the quantity of fruits is important, their quality is equally important, therefore the physico-chemical properties are not a factor to be ignored and that is why periodic analyzes are carried out. Thus, the variety with the highest malic acid content is the ‘Szampion’ variety with 0.43 g/l ac. malic, at the same time this variety recorded the highest content of soluble dry matter 12.60°Bx.
