Improvement in radicle and plumule lengths and root score and seedling fresh and dry weights (Tables II, III) seems the involvement of B in meristematic growth of radicle and plumule primodia (Bohnsack and Albert, 1977), cell wall extensibility (Bell et al., 1989) and cell division and elongation (Shelp, 1993).

This led to a series of different typological classifications being proposed over the years with embryo types being characterised and named after various genera.In the first attempts of composing an embryo typology, only three characters were used: (1) the major outline of the embryo, (2) the position of the developing plumule, and (3) the position of the root cap.
