Abstract
The present study aimed to establish a system to regenerate an ornamental and endemic species Chirita heterotricha Merr. A procedure for the in vitro plant regeneration from leaf explants of C. heterotricha is described. Culturing small leaf-sections of C. heterotricha on MS medium supplement with 0.1 mg l-1 NAA and 0.1 mg l-1 BA resulted in the highest adventitious buds induction rate (39.5 adventitious buds per explant). Consequently, regenerated plants were established after rooting of shoots on half-strength MS medium with 5 g l-1 activated charcoal, 30 g l-1 sucrose. Rooted plantlets, following acclimatization in a greenhouse, were successfully transferred to field conditions, and 95% of the plants survived. Application of this protocol has potential for mass multiplication of this ornamental species in a limited tim
