(A) Primary callus on filament (Bar: 1 mm).
(B) Primary callus on lateral zones (Bar: 1 mm).
(C) Primary callus on abaxial and adaxial zones (Bar: 1 mm).
(D) Pro-embryogenic callus derived from filament (Bar: 1 mm).
(E) Pro-embryogenic callus derived from lateral zones (Bar: 1 mm).
(F) Pro-embryogenic callus derived from abaxial and adaxial zones (Bar: 1 mm).
(G) Pro-embryogenic callus derived from entire anther (Bar: 1 mm).
