title: Site of production of gibberellin-like substances in germinating barley embryos.
abstract: It has been shown that gibberellin-like substances are produced in the scutellum of barley embryos during the first two days of germination (at 25°). This production is not stimulated by mevalonic acid or sugar, but it is inhibited by CCC. On the third day the activity of the scutellum ceases and the axis probably commences to produce gibberellins. Both gibberellic acid and gibberellin A1 appear to be present, the latter predominating.
