Fig. 4. TEM analyses of different developmental stages of somatic embryos of L. montana. Formation of cell with large vacuole (V), mitochondria (M), nucleus (N) and nucleolus (NU) in globular embryos (Bar, 0.5 μm) (A). More vacuolated with cytoplasmic organelles in SM regions of pear-shaped (Bar, 0.5 μm) (B) and early torpedo-shaped (Bar, 0.5 μm) (C) embryos. Development of cytoplasmic components with nucleus (N), nucleolus (NU), Golgi apparatuses (GA), mitochondria (M) and chloroplasts (CP) in SM regions of torpedo (Bar, 0.5 μm and 0.2 μm) (D) and cotyledonary embryos (Bar, 0.5 μm) (E). Large intercellular spaces (IS) and thick cell wall (CW) in connective regions of SM and RM of cotyledonary embryos (Bar, 0.5 μm and 0.2 μm) (F). Development of thick IS and CW with cytoplasmic components of mitochondria, starch grains (SG) and plastids (PS) in RMs of torpedo (Bar, 0.2 μm) (G) and cotyledonary (Bar, 0.5 μm and 0.2 μm) (H) embryos.
