GEORGIEV, S., A. TASHEV and K. KOEV, 2013. Eco-biological characteristics of medicinal plants in the maintained reserve “Balabana” (the river Tundzha hilly valley). Bulg. J. Agric. Sci., 19: 353-360
In the present work we investigated medicinal plants of the flora of the maintained reserve “Balabana”, located in the middle reaches of the river Tundhza, near Elhovo (Tundzha hilly valley). A characteristic was made of the systematic structure of the eco-biological features of these plants. The species were grouped in biological groups, life forms, floral elements and flowering period. Medicinal plants were also classified according to their relation to water, light, heat and substrate.
