| Abstract: | Begonia

elatior
plantlets which regenerated from leaf disk callus showed variations in plant morphology, number of flowers per plant, and
flower size. Variations in flowering period, number of flowers per plant, and flower morphology were observed in
Saintpaulia ionantha
L. plants directly regenerated from leaf disk explants. The cytokinins, benzylaminopurine and zeatin, tested in the culture
medium did not affect the basic plant characteristics including flower colour which remained stable in both species. Micropropagation
of selected somaclones having the desirable trait of high number of flowers per plant was stable in the MV2 and MV3 generations. |
