Abstract:

Various factors which affected the embryogenesis for pepper were induced, including donor plant, microspore developmental stage, basal media, plant growth regulators, supplements to the culture media and temperature stress treatment. Cytological studies of microspore embryogenesis, ploidy level of regenerants and diploidization of the genome were summarized. It also pointed out that although there had been a considerable increase in the amount of information concerning cellular and molecular aspects involved in microspore embryogenesis induction and embryo formation, still very little was known about the mechanism behind the change of pathways from gametophytic to embryonic. When the mystery of microspore embryogenesis was completely revealed, the technique for anther culture in pepper will be applied in more fields.
