Micropropagação de croton antisyphiliticus mart

Abstract

Croton antisyphiliticus Mart. ex M. Arg., popularly known as "pé-de-perdiz", is a native medicinal plant of Cerrado, whose root is used in the form of decoctions against infections of the male and female reproductive. The collection of the plant is carried through of extractives form and there are no studies regarding its conservation. The aim of this study was to establish a micropropagation protocol of C. antisyphiliticus. The effect of different concentrations of cytokinins, the size of the container for the in vitro culture, co-cultivation and bud position in relation to the development of the explants, as well as the influence of AIB on in vitro rooting and acclimatization of explants were evaluated. The best development in vitro was obtained with apical explants co-cultivated on MS medium supplemented with BAP (1μM) in bottle type pot. Rooting was achieved on MS medium without growth regulators and acclimatization can be performed in Cerrado soil without the presence of shoots developed roots in vitro.
