Abstract:
of 22.5 and 52.5 ml was applied per plant at 7 and 11 weekly intervals. Some plants were sprayed with water to serve as controls. Pollen development in the treated plants was studied in detail to find the stage at which FW-450 takes effect. Pollen development was studied in control plants for comparison. Results of this study showed that meiosis in the PMCs from the control plants was normal leading to the formation of well developed pollen grains. PMCs from the treated plants, on the other hand, showed abnormalities like unequal distribution of chromosomes during anaphase I & II, leading to the formation of abnormal tetrads containing some micronuclei in addition to abnormal microspores.
