The life-history ofOttelia alismoides pers

  • Published:
Proceedings / Indian Academy of Sciences

Summary

  1. 1.

    The microspore tetrads are arranged in isobilateral, linear or decussate manner. The tapetum forms a periplasmodium. The pollen grain has a conspicuous generative cell and a degenerating tube nucleus. The degeneration of some of the pollen grains is also observed. The endothecium is not well developed.

  2. 2.

    In the nucellus there is usually a single archesporial cell which directly functions as the megaspore mother cell. Occasionally, a multicellular archesporium is noticed.

  3. 3.

    The embryo sac is normal in which the antipodals are organised into cells.

  4. 4.

    The embryo is of theSagittaria-type.

  5. 5.

    The primary endosperm nucleus divides accompanied by a wall formation. The upper chamber lodges the embryo and the lower one along with the persisting antipodals assumes a haustorial rôle. The endosperm tissue is feebly developed.
