STRUCTURE OF PERECHYMA OF PEAR FRUITS DEPENDING ON MINERAL NUTRITION

The structure of the parenchyma of pear fruit plays a leading role in harvesting the fruit and their subsequent storage for commercial sale. The size and structure of parenchyma cells, on which the mechanical strength of the fetus and tasting qualities depend, are important for this. The research was conducted in the conditions of the pear orchard of the Uman National University of Horticulture. Laboratory studies of the parenchyma of the pear fruit were carried out during the growing season in 2019 as the size of the fruit increases (1 - 14.07; 2 - 16.07; 3 - 12.08; 4 - 26.08; 5 - 13.09) in laboratory conditions according to the method of V. Zamorsky. The study of the anatomical structure of pear fruits of the varieties Osnovyanska and Conference showed that at the initial stage of formation of pear fruits the use of additional mineral nutrition does not affect the size of parenchymal cells. The increase in the parameters of parenchymal cells was due to the use of mineral fertilizers in the amount of N90P60K90, groundwork + N30K30 and groundwork + N30
