Physiological Mechanism of the 24-Epibrassinolide Action on Potato Plant-Regenerants of Lougovsky Variety Under Hydroponic Condition

Abstract

It was shown that during the adaptation of potato plants to the hydroponics conditions, the growth rate of shoot and leaves decreased, the flavonoids content in leaves increased. Root treatment with 24-epibrassinolide (EBL) stimulated the growth of shoot and leaves, the formation of stolons and tubers. EBL changed the functional state of the leaves. It increased the content of photosynthetic pigments in them, the intensity of photosynthesis, transpiration and lipid peroxidation against a background of low flavonoids content.
