Abstract

In the northwestern agro-ecological region of the country, with its shortened plant growing season, plant resistance to various diseases, early harvests, and problems of their storage, a promising and effective intervention is the use of growth stimulants. To enhance growth, plants were treated with an amino acid preparation (glycine) at dosage rates 20, 40, 60, 80, 100 and 120 mg/l. The reference sample was treated with water. The experimental samples exceeded the reference in mean fruit weight; the greatest increase of fruit weight and dry matter content was observed in the 5th sample (fruit weight: 0.79 g, dry matter content: 10.2%). Sample No. 3 contained the highest amount of sugars, with the preparation’s dosage 40 mg/l: 9.56%, which was higher than the reference by 2.44% (sample No. 1). This excess refers to monosaccharides and disaccharides. The content of malic, citric, oxalic and tartaric acids in all experimental samples was higher than in the reference; the best results were shown by sample No. 6, with the dosage 100 mg/l.
