Rezumat: VIEW PDF: PHYSIOLOGICAL EFFECTS OF THE IN VITRO CULTURE ON EXPLANTS BELONGING TO SOLANUM GENUS A large variety of secondary metabolites are responsible for specific defense mechanisms against stress factors in plant tissues. Among them, phenols and thus flavonoids play an important role, due to their strong antioxidant activity and the fact that their quantity is rapidly increasing if a specific stressful factor appears in the environment. In this context, we evaluated the physiological effects of the in vitro culture on explants, by quantifying the total polyphenolic content (TPC), the total flavonoid content (TFC) and the antioxidant activity (AA), both under in vitro and ex vitro conditions. Our experiments were performed on 2 closely related species of potato: the wild species S. bulbocatanum and the potato commercial cultivar S. tuberosum ‘Rasant’ and on two somatic hybrids between them, obtained through protoplast electrofusion. |
