From: High temperature-induced production of unreduced pollen and its cytological effects in Populus
High temperature-induced pollen and untreated control pollen. (A) Pollen collected from untreated buds; (B) High temperature-induced pollen, showing large pollen grains (arrows) and aborted pollen grains (arrow heads); (C) Tetrad shaped aborted grains failed in cytokinesis (arrows); (D) Conjoined grains failed in microspore segregation (arrow); (E) Control pollen with DAPI staining; (F) High temperature-induced pollen with DAPI staining, showing a large grain with large gametophytic nuclei. Bars = 50 μm.
