In vitro culture of Spondias mombin L. nodal segments

Cultura in vitro de segmentos nodais de Spondias mombin L.

Spondias mombin L. shoot cultures were initiated from nodal explants taken from plants propagated by seeds. Explants coming from 4-6 months old plants, previously disinfected, were cultivated on WPM medium supplemented with a wide range of concentrations of BAP (0.0, 0.22, 0.44, 2.22 and 4.44 muM) and NAA (0.0, 0.27 and 2.70 muM). After four weeks, the responses obtained were axillary shoot and root formation. The first response were preferentially induced with the medium containing only BAP, regardless of the BAP concentration. The addition of NAA on medium reduced significantly axillary shoot formation and induced rhizogenesis. Roots were formed on nodal explant basis, preferentially on medium supplemented with 4.44 muM NAA. The medium supplemented with BAP reduced significantly root formation.
