Embryo Culture for the Production of Interspecific Hybrids in Zantedeschia

概要

論文の詳細を見る
To establish an optimum method for the production of interspecific hybrids between Zantedeschia aethiopica (group 1) and Zantedeschia spp. except Z. aethiopica (group 2), the development processes of hybrid embryos and endosperms after fertilization were observed, and a suitable medium for embryo rescue was studied. Interspecific hybrids were obtained efficiently when embryos excised from ovaries 6-8 weeks after pollination were cultured on MS medium containing 0.1mg・liter^<-1> NAA and 1.0mg・liter^<-1> BA. But, all hybrids were albino and only viable in vitro and so further studies are required to conquer the postfertilization barrier.
