Anther ontogeny in Campsis radicans (L.) Seem. (Bignoniaceae)

, 2013
In this study anther ontogeny of Campsis radicans (L.) Seem. was investigated by transmission electron microscopy and light microscopy with special reference to the development of the anther wall. The anther wall formation follows the dicotyledonous type.
