K. KHATOON AND R. SULTANA
Abstract
Petiole segments and excised epidermal thin cell layers of Carica papaya N. Malir were cultured on full strength MS medium containing a range of concentrations of nephthalene acetic acid (NAA) and isopentenyl adenine (2iP) used seperately and in combination. Petiole segments and epidermal thin cell layers formed maximum callus on medium containing 2.5 mg/1 NAA plus 0.5 mgll2iP and 1 mg/1 NAA plus 1 and 5 mgll 2iP respectively. Enhanced callus growth and shoot formation occurred on half strength macro inorganic salts of MS medium containing 2.5 mg/1 NAA plus 0.5/1 mgll 2iP alongwith 15% coconut milk. Regenerated shoots produced roots on half strength macroinorgani
