Abstract

GUZZO, Flavia; CEOLDO, Stefania; ANDREETTA, Filippo  and  LEVI, Marisa. In vitro culture from mature seeds of Passiflora species. Sci. agric. (Piracicaba, Braz.) [online]. 2004, vol.61, n.1, pp.108-113. ISSN 1678-992X.  http://dx.doi.org/10.1590/S0103-90162004000100018.

The genus Passiflora comprises hundred species, mainly native of the South American tropics and rainforests, which are grouped into 21 subgenera. Some species are widely studied for their economic importance and are chiefly cultivated for production of fruit juice. To obtain a continuous source of material for a screening of secondary metabolites, zygotic embryo culture was attempted for 62 Passiflora species, starting from seeds mainly collected in the wild. Twenty nine of these species produced calli, which had very different growth rates. Plants were successfully regenerated from calli of 13 different species. For 25 of the responsive species this is the first report of in vitro culture.

Keywords : Passiflora regeneration; embryo culture; endosperm culture; ethnobotanical species; plant acclimatization.
