Abstract
An efficient protocol for the micropropagation of Drosera anglica, D. binata and D. cuneifolia is described. Proliferation was obtained from leaf segments and shoot tips, which served as initial explants. The regeneration capacity of explants was influenced by factors such as nutrient media, concentrations of growth regulators and the type of medium (liquid or solid). The highest number of plants regenerating from D. binata explants was obtained on the growth regulator-free Vacin and Went medium. In the case of D. anglica the highest proliferation rate was obtained on the Fast medium supplemented with 0.05 μM 6-benzyladenine (BA) and 0.005 μM α-naphthaleneacetic acid (NAA), whereas for D. cuneifolia the optimal regeneration medium proved to be 1/2 MS with the growth regulator supplementation estimated at 0.2 μM BA and 0.2 μM NAA. Liquid media significantly increased the regeneration potential of D. anglica and D. binata explants.
