Fig. 4.

Changes in a soybean during imbibition at a longitudinal section (Fig. 1C, α) normal to the raphe–antiraphe of the longer axis in the initial stages of imbibition. The same three-dimensional image data as presented in Fig. 3 were processed to indicate the protrusion of the radicle. The images are presented at 30-min intervals from 35 min to 3 h 35 min of imbibition: (A) 35 min, (B) 1 h 5 min, (C) 1 h 35 min, (D) 2 h 5 min, (E) 2 h 35 min, (F) 3 h 5 min, and (G) 3 h 35 min.
