Oil body dynamics in olive pollen grains (A) and pollen tubes (B) at different times of germination in culture medium with sucrose (dashed line) and without sucrose (solid line). Values are mean ± SD from Z-series images corresponding to 45 germinated pollen grains from three independent experiments (N = 45). Asterisks correspond to significant difference (P ≤ 0.01); ns, no significant difference.
