The Influence of Agrotechnological Tools on cv. Rubin Apples Quality

With the growing demand for quality food in world, there is a new ambition to produce high-quality apples seeking reduced cultivation costs. The aim of this study was evaluate influence agrotechnological tools on cv. Rubin during harvest. apple tree (Malus domestica Borkh.) grafted dwarfing rootstocks P60, planted single rows spaced 1.25 m between trees and 3.5 rows. Six were used—hand pruning, mechanical trunk incision, calcium-prohexadione, summer pruning one side, changing sides annually. agrotechnical had no significant effect accumulation most sugars elements, malic, folic succinic acids fruits. Mechanical resulted phenolic compounds, antioxidants, ascorbic acid, but amount glucose compared hand pruning. However, incision or spraying with ca-prohexadione together sugar content significantly higher amounts phenols, Fe Mn starch citric acid.
