propagation

rooting

A protocol was developed for shoot proliferation and plantlet formation of Khaya senegalensis, an important medicinal and timber plantation species introduced to Australia and southern Asia from western and central Africa. We assessed effects of the plant growth regulators, benzyladenine, kinetin, naphthalene acetic acid and gibberellic acid, on shoot proliferation and subsequent plantlet conversion. Shoot proliferation over four passages was higher in media containing benzyladenine than in media containing other growth regulators, and optimal proliferation from seed of three different sources was consistently obtained in medium containing 4.4 μM benzyladenine. Shoots from this medium were converted to plantlets at high frequencies (76-90%) after treatment with 19.6 μM indole-3-butyric acid, and almost all plantlets were successfully acclimatized to nursery conditions. These methods provide the means for establishing in vitro and ex vitro clone banks of juvenile K. senegalensis trees for field selection of desired genotypes and tropical plantation establishment.
