Different structures and embryogenesis pathways in microspore cultures at 18°C. Panoramic views of cultures at 13 days (a) and 17 days (b, c) showing different structures and embryogenesis pathways at the same time points: small dead cells (thin arrows), rounded multicellular structures surrounded by exine (thick arrows) and uniseriate structures (open arrows) of two-three cells at 13 days (a) and longer structures at 17 days (b, c). b, c) Phase contrast (b) and DAPI epifluorescence (c) views of the same microscopic field.
