Cyto embryological studies on indian taraxacum spp 1. micro sporangium micro sporogenesis and micro gametogenesis



Cytologia (Tokyo) 47(1): 125-136



Microsporogenesis in 10 spp. of Taraxacum [T. flavum, T. gulmargense, T. harbhajan-singhii, T. tenebristylum, T. vulpinum, T. himalaicum, T. polyodon, T. banhyhalense, T. duplidense, T. wallichii] was studied. Meiosis is both of regular and irregular type resulting in the formation of regular tetrads, dyads, triads, pentads and hexads. The resulting spores are of reduced and of unreduced types. A scheme is prepared to cover the majority of the most frequent abnormalities during microsporogenesis in Taraxacum spp. The reason for the meiotic disturbances also is discussed.
