Fertility observation in the process of fertility transition for WXA. (A) Mature, normal anthers of WXS (F) observed by stereo microscope. (B) Mature anthers of WXS (F) stained darkly with 1% potassium iodide solution (I2-KI). (C) Mature anthers of WXS (S) observed by stereo microscope. (D) Mature anthers of WXS (S) stained with 1% potassium iodide solution (I2-KI). Carbol fuchsin dyeing of the WXS (S) (E,a–d) and WXS (F) (E,e–l) microsporocytes from the pollen mother cell formation stage to the pollen meiosis stage. a, e, f were considered the pollen mother cell formation stage; b, c, g, h, i, j, k were considered the meiosis stage; d, l were considered the mononuclear stage.
