Effects of NPA treatment on ail6-2 inflorescences. A. Ler inflorescence 11 days post NPA treatment. B. Scanning electron micrograph of Ler inflorescence fixed 9 days post NPA treatment. The red arrow points to a stage 4 flower and the numbers mark all flowers initiated prior to the stage 4 flower. C. ail6-2 inflorescence 11 days post NPA treatment. D. Scanning electron micrograph of ail6-2 inflorescence fixed 9 days post NPA treatment. The red arrow points to a stage 4 flower. The number 1 marks the last flower initiated prior to temporary termination of floral meristem initiation. E. Floral organ number in mock and NPA treated Ler and ail6-2 inflorescences from 12-15 days post treatment. Data are means ± SD. F. Incidence of sepal fusion in mock and NPA treated Ler and ail6-2 flowers counted 12-15 days post treatment. G. Scanning electron micrograph of an NPA-treated ail6-2 flower that exhibits sepal fusion. Arrows point to a region of fusion. Size bars correspond to 200 μM in B, D; 200 μM in G.
