Microstructural Observations and Cytochemical Studies on the Archegonial Development and Oogenesis of Marchantia polymorpha
地钱颈卵器发育和卵发生的显微观察及细胞化学研究

The development of archegonium and oogenesis of the hepatica Marchantia polymorpha were studied using microscopical and cytochemical techniques.The archegonium developed from an initial cell,which formed an apical cell and a basal cell by a transverse division.The apical cell produced an inner primary cell by three oblique vertical divisions and a transverse division.The primary cell formed a central cell and a neck canal mother cell by a transverse division.The central cell formed an egg and a ventral cana...
