Comparison of the explant types showed that the flamingo-bill type explant had better shoot formation than did the proximal explant. The MS medium containing 1 mg l(-1) of BA was optimal for shoot formation capacity when flamingo-bill type explants germinated in the dark (44%) and light (36%) were used. Histological analysis showed that explant cell division began after 3 days in regeneration medium and formation of primordium was observed in the tissues in culture between days 5 and 7. Differentiation of meristimatic structures was first observed after 9 days and development completed after 9-12 days in the culture.eninfo:eu-repo/semantics/openAccessBottle GourdLagenaria sicerariaregenerationhistologyexplant typeArticle33216517210.3906/tar-0806-292-s2.0-70350763925Q1WOS:000266361100008Q3
