Fig. 7. Hypothetical model of water loss of an individual shelled maize seed, A) evaporation of water from seed surface; B) water migration from internal tissue as maturation drying progresses (Bar = 80 µm); C and D) water movement to intercellular space early during drying and more advanced drying stage (notice the alignment of lipid bodies along the plasma membrane). Arrows denote water movement; Bar = 2 µm.
