Fig. 2. Stigma morphology of almond flowers 4 (A–C) or 24 h (D–F) after spraying with water. A, Pistil morphology in almond is characterized by a circular, bilobed stigmatic surface that expands slightly in a fan‐like manner beyond an elongated and cylindrical style. B, Stigmatic surface cells are composed of raised papillae. C, Slight exudate secretions accumulated in interstices at the base of papillae; arrow indicates exudate accumulation. D–F, Showing variable exudate production. D, Slight accumulation, similar to that at 4 h. E and F, More extensive exudate accumulation.
