Fragments resulting from cutting treatments and M. coquimbensis seedling. (a) Mature WIS. (b) Fragments resulting from seeds cut into two; note that only one of the cotyledons (right) has the embryonic axis. (c) Fragments resulting from seeds cut into three; again, only one of the fragments (bottom left) has the embryonic axis. (d) Normal seedling development from a mature WIS. Arrows show the position of the embryonic axis.
