Abstract
The purpose. To study influence of features of a kind and weather environment upon formation of the content of essential ingredients of chemical composition in fruits of dogwood grown in Right-bank Foreststeppe of Ukraine. Methods. Laboratory, chemical, comparative-calculation. Results. In conditions of Right-bank Forest-steppe depending on the kind and weather environment of growing fruits of dogwood accumulate: dry matters – 18,5 — 26,8%; dry soluble substance – 15,6 — 23,9; sugars – 5,9 — 10,5; acids – 2,38 — 3,10 %; ascorbic acids – 70,2 — 93,6 mg/100 g. Conclusions. Strong converse connections between the content of dry solvends in fruits and rainfall of vegetation period are determined: with increase of rainfall the content of dry solvends and total sugars in fruits is decreased. Essential influence of weather environment in winter-spring season, in particular rainfalls, on the content of dry solvends, sugars and titrable acids in fruits of dogwood is fixed.

Key words: dogwood, kind, weather environment, chemical composition.
