In Vitro Plantlet Production from Young Capitulum Explants of Gerbera jamesonii

Two clones of Gerbera jamesonii were propagated in vitro from fragments of young capitulum, 0.5 to 0.7 cm in diameter. These were cut into 20 to 25 explants and placed on several media. Media containing 0.57 μm (0.1 mg/liter) indole-3-acetic acid (IAA) and 4.4 or 8.8 μm (1 or 2 mg/liter) 6-benzylaminopurine (BA) gave best shoot production. Three mineral solutions were tested. All shoots over 0.5 cm rooted regardless of the IAA level in the medium.
