Pro-embryos induction from Olea europaea L. isolated microspore culture
Studies were undertaken with one olive (Olea europaea L.) cultivar to identify buds with microspores competent to embryogenesis in vitro. Isolated microspore cultures were performed for the induction of gametic embryogenesis. Different pollen development stages and stress conditions (heat or cold shock) were evaluated. The correlation of inflorescence, anther morphology and the suitable stage of microspore development were analysed. The morphology of responsive buds was identified which corresponded with microspores from the late uni-nucleate to early bi-nucleate pollen stages. Symmetrical divisions of microspores as well as resulting multinucleate structures and pro-embryos were observed. In this paper, a new method of isolated microspore culture that leads to cell division and pro-embryos in olive, is reported.
