• The relation between pollen stage and the plantlet formation and the process of embryogenesis from pollen grain were studied by using two varieties of Nicotiana tabacum. Haploid plantlets were induced from immature pollen grains in uninuclear to early binuclear stage and no plantlet was formed in tetrad stage in both varieties. In the process of embryoid fcrmation from immature pollen grain, it was clarified that the vegetative nucleus played the main part of embryogenesis and the generative nucleus rarely divided. Two types of cell division were also observed, one of which had clear cell walls and the other had not. The cause of these phenomena were discussed.
