  • a All plants were grown under the same conditions. The average number of organs per flower is given.

  • b Numbers refer to the positions of the flower on the inflorescence, with flower 1 being the first flower to develop.

  • c T(AP3-11) and T(AP3-1) refer to plants that contain a transgenic copy of the AP3 gene from ap3-11 and ap3-1 plants, respectively.

  • d Stamens (St) produce visible pollen grains.

  • e Stamens do not produce visible pollen grains.

  • f Carpelloid (C) stamens. Organs primarily staminoid with carpelloid features, as described in Bowman et al. (1989).

  • g Staminoid carpels. Organs primarily carpelloid with staminoid features, as described in Bowman et al. (1989).

  • h Includes various types of filaments and filamentous structures.

  • i Includes other types of mosaic organs.
