Аннотация

The photosynthetic productivity of peaches of the following kinds: Kollins, Moldavskii jeltii and Redhaven have been studied with different fruit load in the conditions of lysimetres. The fruit-bearing trees have been studied during the season according to vegetation phases. CO2exchange of gases, transpiration and respiration, composition and quantity of photosynthetic de pigments, as well as the monitoring of production process have been established. The characteristics of highly productive plants have been discovered, the regulating influence of the quantity of attraction centres on the photosynthetic activity of fruit-bearing plants has been established.
