The paper presents the effectiveness of various propagation methods applied to several pawpaw (Asimina triloba (L.) Dunal) genotypes. Generative propagation, propagation by grafting, and by cutting have been studied. Various generative propagation methods as seeds exposure to polarized light and different magnetic fields before sowing and to LED light, throughout the germination period have been tested. The grafting was performed at different times of the year (spring and autumn) on one-year-old rootstock. Following the conducted research, it was concluded that the most effective propagation methods were seed propagation and grafting, while propagation through cuttings was inefficient. By subjecting the seeds to magnetic fields and LED light before sowing, the germination period was significantly reduced, and their germination capacity increased. The most optimal period for grafting was early spring, after the rootstocks started the vegetative growth.
