Оценка качества плодов сливы и яблони по некоторым биохимическим показателям, в зависимости от генотипа и условий выращивания [Articol]

Abstract

The article presents the results of studies on biochemical characteristics that demonstrate the quality of plum and apple fruits. In fully ripe fruits, polyphenoloxidase activity and accumulation of phenolic substances were determined. The experiment was carried out in lysimeters on trees grown under different conditions (with irrigation and moisture deficit). The results of the study show that some plum and apple varieties demonstrated a higher level of polyphenoloxidase activity, which may be due to their adaptation to stress conditions, such as changes in temperature and humidity. It was determined that the accumulation of phenolic substances in fruits depended on both growing conditions and biological characteristics of varieties. The highest level of enzyme activity and content of the studied substances was observed in plum fruits. The results obtained during biochemical studies on plum and apple provide important information on the effect of growth conditions on their drought resistance and its relationship with fruit quality.
