Abstract
We have further investigated dimethylarsinic acid because of its possible gametocidal activity, using the prolific-seeding pearl millet, Pennisetum typhoides (Burm.) Stapf and C. E. Hubb. Seed set, pollen stainability, chromosome pairing, length of tillers, and other characteristics were evaluated. Foliar-spray applications (183 grams per hectare) at early growth stages selectively modified floral structures, the gynoecium being the most sensitive. Multiple and intermediately modified pistils were observed in single spikelets. A significant increase in number of chromosome univalents in microsporocytes was associated with treatment dose and seed set was markedly reduced. No one causal factor was found to have a dominant influence on sterility, although selective interference with normal tissue differentiation and retarded cell elongation of floral structures played an important part
