The GAs have long been used in horticultural practice as growth
regulators for crop improvement. Insignificant effects and lack of
toxicity allows a wide range of applications in several cultivated
species, e.g. increasing stem elongation and bract size or colorization (Blanchard and Runkle, 2008) and seedless fruit production
(Retamales et al., 1998). In woody angiosperms flowering is generally associated with reduced stem elongation. It may be proposed
that the role of GAs in flowering of different plant groups reflect the
relationship between stemelongation and flowering (Goldschmidt,
