Fig. 8.

Water migration from the entrance to the radicle along the hilum, following rapid water entry into the dorsal testa in the initial stages of imbibition. The same three-dimensional image data as presented in Fig. 7 were processed. The MIP images from α to β sections in Fig. 1C are presented from 1 h 5 min to 4 h 20 min of imbibition. (A) 1 h 5 min, (B) 1 h 20 min, (C) 1 h 35 min, (D) 1 h 50 min, (E) 2 h 5 min, (F) 2 h 20 min, (G) 2 h 35 min, (H) 2 h 50 min, (I) 3 h 5 min, (J) 3 h 20 min, (K) 3 h 35 min, (L) 3 h 50 min, (M) 4 h 5 min, and (N) 4 h 20 min.
