A contribution to the embryology of iridaceae

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

Embryological aspects ofSisyrinchium striatum andS. californicum are studied. The wall of the quadrilocular anther consists of an epidermis, fibrous endothecium, one or two middle layers and a glandular tapetum. The tapetum is of dual origin. Cytokinesis during microsporogenesis are simultaneous. The microspore tetrads are isobilateral or tetrahedral. Pollen grains are shed at two-celled stage. Emryo-sac is of the Polygonum type. Endosperm is Nuclear. The apical cell of the two-celled proembryo contributes to the development of the embryo proper and part of the suspensor. The basal cell which may or not divide forms the suspensor.
