Growth and Endogenous Gibberellin Content of Dormant Groundnut Embryonic-axes as Influenced by Leaching and GA(3).

Leacthing the excised embryonic-axes from dormant groundunt (Arachis hypogaea) seeds resulted in their growth. However, their growth was stunted compared to that of after-ripened ones. It is attributed to (1) the lower amount of gibberellin-like substances in the dry, dormant embryonic-axes than in the after-ripened ones, and (2) the inability of the former to sythesise tbe tibberetllin as indicated by the lower content compared to the after-ripened ones kept in water.
