In vitro establishment and micropropagation of Passiflora foetida L.

Among the species of the genus Passiflora, P. foetida L. presents highest genetic variability and also great medicinal importance. This species is used in the treatment of diseases such as asthma, jaundice, and in the form of poultices for erysipelas and skin diseases with inflammation. Therefore, studies are needed to preserve them. Its seeds present dormancy and often take several months to germinate. The tissue culture is a alternative form to propagate species. The objective was to establish and micropropagation P. foetida L., and create a germplasm bank. Seeds were scarified, disinfected, and inoculated on MS medium (½) without regulators for 66 days. Hypocotyls explants obtained of seedlings in vitro germinated were transferred and placed in the same medium supplemented with BAP (1,0 mg L-1). In the establishment phase of 45% of the explants sprouted and formed axillary buds. 88,9% of hypocotyl explants induced shoots and 11,1% produced callus. Seedling measuring 1,82 cm length and rooted were acclimatized.
