In Vitro Culture of Crape Myrtle

by Z.M. Zhang and F.T.Davies, Jr.


Abstract:
Crape myrtle (Lagersroemia indica L. ‘Near East’) explants of 2 nodes were cultured on woody plant medium (WPM) supplemented with PBA, BA, or kinetin. PBA was most effective in promoting axillary shoot proliferation. Maximum number of axillary budbreaks occurred on modified WPM containing 3-9  M PBA. Subcultured shoots2 cm in length rooted in medium without auxin, and ex vitro rooting and acclimatization was also obtained. Chemical names used: 1H-indole-3butanoic acid (IBA); N-(phenylmethyl)-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (PBA), N-(phenylmethyl)-1H-purin-6-amine (BA); N-(2-furanylmethyl)-1H-purin-6-amine (kinetin).
