Representative embryo development stages of B. napus. (A) globular-shape embryo stage; (B) heart-shape embryo stage; (C) cotyledon stage; (D) sectioning of a seed with heart-shape embryo is shown to illustrate the green endosperm tissue. Abundant chloroplasts surrounding central vacuole of the harvested endosperm cells are clearly visible (insert). Bars = 50 μm.
