Abstract:

Spiegel-Roy P. and Kochba J. Stimulation of differentiation in orange (Citrus sinensis) ovular callus in relation to irradiation of the media. Radiation Botany 13, 97-103, 1973.-Gamma irradiation of ovular callus of Shamouti orange (Citrus sinensis) caused a marked stimulation in embryoid formation at a dose of 16 kR. Doses of 28-32 kR proved lethal. Irradiation may cause a shift from conditions favourable for callus growth to those favouring embryoid formation. Irradiation of the medium, containing malt extract, caused as much embryoid stimulation as did irradiation of callus and medium. In media containing adenine, irradiation led to cessation of both callus growth and embryoid formation. With low kinetin and IAA, irradiation depressed callus growth and stimulated embryoid differentiation. © 1973 Pergamon Press Ltd.
