摘要:: 以萝卜为试材，采用形态学解剖、细胞微结构观察等方法对萝卜角果、胚珠和胚胎的发育情况进行全程追踪，以期为萝卜种子含油机理研究提供参考依据。结果表明：萝卜胚珠及胚胎在拐杖胚时期质量急剧上升，超微结构观察表明球形时期胚胎最外层细胞开始出现分化，且油体在拐杖形胚胎时期向子叶胚胎时期发育的萝卜胚胎细胞中大量出现。该研究揭示萝卜胚胎发育形态及油体动态变化趋势，为进一步研究萝卜种子发育规律和油体形成过程奠定了基础。

Abstract:: Radish was used as test material，the dynamic process of silique ovule and embryo in radish was traced via morphology and comparative embryology，in order to excavate the radish seed oil formation mechanism.The results showed that the weight of radish ovule and embryo increased sharply at bent-embryo stage.Ultrastructure observation indicated that peripheral cell around globular embryo began to differentiate and oil body started to appear at bent-embryo stage.The study revealed dynamic process of oil body formation in embryo development and provided an important theoretical reference for the formation of fatty acids in radish seeds.
