Role of the Generative Cell in Androgenesis in Henbane

V. RAGHAVAN 1

1 Department of Botany, Ohio State University, Columbus 43210

When anthers of henbane containing uninucleate pollen grains were cultured, a large number of embryoids originated exclusively from the division of the generative cell. In a small proportion of pollen grains, both generative and vegetative cells contributed to embryoid formation. Embryogenesis by segmentation of the vegetative cell alone was rarely observed.
