摘要: 为了探索油菜外植体分化再生的机理, 利用扫描电镜技术对芥菜型油菜DB的下胚轴、子叶在不同的离体培养时期的细胞分化和形态变化进行了研究.结果表明, 下胚轴外植体是切面上的维管束薄壁细胞和距离切面400~600 μm的薄壁细胞脱分化, 然后再分化形成芽.而子叶仅仅是距离切面400~600 μm的薄壁细胞脱分化后再分化成芽的.

Abstract: In this study, hypocotyl and cotyledon of B. juncea, cultured in vitro at different time, were scanned by scanning microscope. The results indicated there were two kinds of cells de-differentiated and then differentiated shoots in hypocotyls. One was parenchyma cells of hypocotyl vascular bundle on cut face, the other was parenchyma cells about 400- 600 Lm away from cut face. But parenchyma cells of cotyledon did only from the later.
