Abstract

WE reported earlier1 that the mature anthers of Datura produce numerous embryo-like structures when cultured on Nitsch's medium containing 15 per cent coconut milk. We suggested two possibilities for their origin: (1) from the connective tissue; (2) from the pollen grains. The precise situation, however, could not be determined at that time. We now report evidence which shows that these embryoids originate from the pollen grains.
