In vitro micropropagation of an endemic fruit tree Syzygium alternifolium (Wight) walp

Shoot proliferation was obtained from shoot tip and nodal bud explants ofSyzygium alternifolium (Wight) walp on modified Murashige and Skoogs medium (MS) supplemented with either BA, KN or AD alone or BA in combination with either IAA, NAA or IBA. A combination of BA and auxins produced more shoots from both types of explants than on the medium containing only cytokinins. The highest multiplication rate was achieved with nodal bud explants in presence of 17.7M BA and 2.6M NAA. Excised shoots were rooted on half-strength MS medium with either IAA or IBA. The regenerated plantlets have been successfully acclimatized and transferred to soil. About 70% of plantlets have survived underex vitro conditions.Abbreviations BA-N⁶ Benzyladenine - KN Kinetin - AD Adenine - IAA Indole-3-aceticacid - IBA Indole-3-butyricacid - NAA-1 Naphthalene aceticacid - MS Murashige and Skoogs medium (1962)
