Effects of NPA treatment on ant-4 flowers. A. Mock (left) and NPA (right) treated ant-4 flowers 11 days post treatment. B. Scanning electron micrograph of a NPA treated ant-4 flower fixed 9 days post treatment. Arrows point to filaments present in the second whorl. C. Organ types found in second whorl of mock and NPA-treated Ler and ant-4 flowers. D. Scanning electron micrograph of a second whorl filament. E. Scanning electron micrograph of a second whorl thin petal. F. Floral organ number in mock and NPA treated Ler and ant-4 inflorescences from 10-12 days post treatment. Data are means ± SD. G. Floral organ number in mock and NPA treated Ler and ant-4 inflorescences from 13-15 days post treatment. Data are means ± SD. H. Incidence of sepal fusion and stamen fusion in mock and NPA treated Ler and ant-4 inflorescences. Sepal fusion was counted in flowers maturing at 13-15 days post treatment while stamen fusion was counted in flowers maturing 10-15 days post treatment. I. Mock (left) and NPA (right) treated ant-4 flowers 13 days post treatment. J. Scanning electron micrograph of an NPA-treated ant-4 flower that exhibits sepal fusion. Arrows point to fused sepals. Size bars correspond to 500 μM in B, J; 20 μM in D; 50 μM in E.
