Abstract
Research aim was to study the influence of foliar treatment with 0.2% succinic (SA) and citric acids (CA) on the morphological and biochemical parameters of the grape plant development at the plant rearing stage. A plant-specific response to biologic active substances was observed: the stem length of Marquette variety was higher after pretreatment of SA (29.1 cm), in CA pretreatment significantly inhibited the growth of the stem (8.8 cm) of Bianca variety compared to SA pretreatment (10.5 cm) and control (14.6 cm). SA and CA pretreatments had a significant effect on the accumulation of monosaccharides, sucrose and chlorophylls b. The influence of CA was to inhibit the growth of the stem and to activate the accumulation of phenolic compounds as compared to the control and SA. The effect of biologically active substances was prolonged, persisting for 24 weeks of research.
