IN VITRO ORGANOGENESIS AND REGENERATION IN CASHEW (ANACARDIUM OCCIDENTALE L.)

M.O. SY, L. MARTINELLI, A. SCIENZA
Cashew morphogenetic capacities were screened through explants prelevated from cotyledons, leaves and petioles.

Callus formation was obtained from leave and petiole explants when different levels of NAA/BAP or 2-4D/BAP were combined on MS modified medium. Adventitious and secondary roots induction occured only when NAA was present. Induction of embryolds from somatic cells was observed after a 12-month subculture on the adaxial face of cotyledonary explant on SH medium supplemented with NAA/BAP (3/0.8 mg 1-1). Moreover a morphogenetic gradient along the cotyledons was noted. On these explants, an increase of NAA (6 mg 1-1) and BAP (1 mg 1-1) rate induced adventitious root formation after a 3-month subculture.
