萝卜离体小孢子培养中的胚胎发生及发育途径
Embryogenesis and Development of Isolated Microspores of Raphanus sativus
摘要
Abstract
[ Objective ] The aim was to observe embryogenesis and development of isolated microspores of Raphanus sativus. [ Method ] By using Chinese radish variety Shandong Huaye Xinlimei as the experimental materials, the caryocinesia features and development of isolated microspore in radish were studied. [ Result ] Two types of cell division appeared in the isolated microspore: unequal division and equational division. The unequal divided microspores had two different size nucleuses, while the equational divided microspores had two same size nucleuses.The equational divided microspores developed to 4-cell structure,multi-cell structure,ball-shaped embryo, heart-shaped embyos, torpedo-stage embryos and cotyledon-stage embryos. [ Conclusion ] This result will provide cytological basis for culture technology of radish isolated microspore.关键词
