Bip. ex Kuntze %A Ayyavu Mahesh %A Devarajan Thangadurai %A Gabriel Melchias %J Biological Research %D 2012 %I Sociedad de Biolog¨Şa de Chile %X An efficient protocol for organogenesis through leaves has been established for Launaea sarmentosa (Willd.) Sch. Bip. ex Kuntze, a highly valuable medicinal plant. The leaf explants produced microshoots on MS basal medium when fortified with cytokinins and auxins. A combination of 6-benzylaminopurine (BAP) at 0.5mg/l and naphthaleneacetic acid (NAA) at 0.2mg/l resulted in the induction of high frequency microshoots in 30 days. The microshoots were successfully subcultured for shoot elongation and eventually for rooting on MS medium supplemented with indole-3-butyric acid (IBA) at 0.5mg/l. The regenerated plantlets were hardened under greenhouse conditions and transferred to garden, resulting in a 90% survival rate. %K Asteraceae %K Launaea sarmentosa %K Leaf explant %K Organogenesis %U http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0716-97602012000200004
