INFLUENCE OF PLANT GROWTH REGULATORS ON MULTIPLICATION OF RARE AND THREATEN MOSS DREPANOCLADUS LYCOPODIOIDES (AMBLYSTEGIACEAE) IN IN VITRO CONDITIONS

Abstract

mass propagation in in vitro and laboratory conditions of D. lycopodioides and thus enable its potential successful reintroduction to the natural habitats. Experiments were carried out to study the influences of essential plant growth regulators, namelly indole-3-butyric acid (IBA) and 6-benzylamino purine (BAP) on moss growth and development. The moss explants were grown on minimal KNOP medium supplemented with exogenously added IBA and BAP (both 0.03, 0.3 and 3 mM and control without growth regulators) for 4 and 6 weeks. After the experiment, morphogenetic parameters such as survival and index of multiplication i
