Сontent of soluble solids, sugars, titrated acids, ascorbate, glutathione, phenolic
substances, anthocyanins, total reducing activity of fruits tissues in sweet cherry fruits studied at
different stages of fruit development during 2018 and 2019 in an organic sweet cherry orchard
(Prunus avium L. / Prunus mahaleb) in the Southern Steppe of Ukraine. The aim of the research
was to determine how the living much conditions (compared to bare fallow) affect the content of
biologically active substances in sweet cherry fruits at different stages of ripening. It was
determined that the fruits of sweet cherry accumulated significantly more ascorbate, phenolic
substances and anthocyanins in the conditions of living mulch (compared to the fruits of the trees
on bare fallow). So, at the stage of picking ripeness, the content of ascorbate in sweet cherry fruits
in the conditions of living mulch was 29 and 22% more compared to bare fallow (respectively, in
2018 and 2019), phenolic substances - by 47 and 23%, anthocyanins - by 36 and 26%. The
revealed regularities can be explained by stressful conditions of competition with natural herbs,
which activate the synthesis of anti-stress, antioxidant biologically active substances in plant
tissues (including fruits). Since it is the antioxidants of the fruits that have a physiological value
for humans, it can be stated that the fruits grown in the conditions of living mulch have a higher
therapeutic and preventive value than the fruits grown on bare fallow.
