Cytoembryological Studies on Indian Taraxacum Weber I. Microsporangium, microsporogenesis and microgametogenesis

Abstract

Microsporogenesis in 10 species of Taraxacum was studied. Meiosis is both of regular and irregular type resulting in the formation of regular tetrads, dyads, triads, pentads and hexads etc. The resulting spores are reduced as well as of unreduced types. A scheme is prepared to cover the majority of the most frequent abnormalities during microsporogenesis in Taraxacum ssp. The reason for the meiotic disturbances is also discussed. © 1982, Japan Mendel Society, International Society of Cytology. All rights reserved.
