Cyto-histological and biochemical studies on pollen abortion in Datura alba plants treated with some gametocides were undertaken. Histological studies revealed that the abortion of pollen in treated plants was associated with the abnormal tapetal enlargement due to starvation caused by poor vascular differentiation. Cytological observations showed minor meiotic abnormality of less significance in the anthers of complete male-sterile plants. Histochemical and biochemical findings corroborated the histological observations as there was a deficiency of carbohydrates, proteins, DNA, histones, enzyme acid phosphatase and free proline in the anthers of complete male sterile plants.It is noted that the mechanism of male sterility induced by gametocides seems to correspond to those of cytoplasmic and genie male sterility which were found in many kinds of plant species.
