Abstract

Vegetative propagation from bulb excised of Eleutherine sp. (Iridaceae) were cultured in Murashige and Skoog (MS) medium supplemented with plant growth regulator (PGR) Benzyl adenine (BA) 1 mg/l at initiation stage, BA (2 and 5) mg/l for induced shoot buds formation at multiplication stage. In this study also BA 2 mg/l and BA 2 mg/l combined with naphthalein acetic acid (NAA) 0.5 mg/l were treated for rooting planlets formation. Calli formation were induced with auxin PGR picloram 1 mg/l combined with 2,4 dichlorophenoxy acetic acid (2,4-D) 0.5 and 1 mg/l in concentrations. The media contained 2 mg/l cytokinin (BA) without auxin (NAA), resulted the highest shoot buds formation. Rooting planlets were produced in MS medium combined with BA and NAA.MS medium contains Picloram 1 mg/l and 2,4-D 1 mg/l was optimal for frequency on
calli initiation (100%) and the largest diameter of calli also represented in cultured MS medium with picloram 1 mg/l and 2,4-D 1mg/l. In acclimatization stage, 100% of planlets survived and successfully transplanted to soil medium in the field.
Key words: in vitro, Eleutherine sp.
