Variation of the first callose plug position from individual C24 plants, flowers and anthers. Variation of the first callose plug in one of 6 individual plants (A), in one of 6 flowers of one plant (B) and one of 6 anthers in one flower (C). The percentages represents the proportion of pollen tubes with the first interval ≥150μm. Arrows indicate a first callose plug with the first interval ≥150μm. Arrowheads indicate a first callose plug with the first interval <150μm. Bars = 100μm.
