The concentrations of gibberellin-like substances in the seed, endocarp, and mesocarp of apricots correlates well with growth rates in these tissues between anthesis and maturity. The active substances are present in high concentration, are more polar than the known gibberellins, and are active in both the barley endosperm and dwarf maize bioassays.
