Abstract

 

A total of 46 species from 3 monocotyledon and 18 dicotyledonous families were investigated for percentage pollen fertility. The average fertility was 91.15% which showed the general stability of the flora in the study area. In the present research the highest 100% value was observed in Argyrolobium roseum (Camb.) Jaub. and Spach and the lowest 66.67% was observed in Spergularia arvensis L. The dominant families regarding number of species were: Brassicaceae having six species, whose average fertility was 91.82% and Papalionaceae having five species whose average fertility was 88.79%. The present studies showed that the flora of the area is a stable one.

 

Key words: Pollen fertility, district tank, sub-tropical flora.
