Hormone Mediated Integration of Seedling Physiology

  • J. E. Varner
Part of the Advances in Experimental Medicine and Biology book series (AEMB, volume 241)


The mobilization of the endosperm reserves of barley seeds (and of many other cereal grains) during the early growth of the seedling is initiated and controlled by gibberellins from the embryo. The gibberellins are synthesized in the embryo tissues after germination begins and have as their principal target tissue the cells of the aleurone layers (Yomo and Varner, 1971). These aleurone cells produce and secrete the hydrolases that hydrolyze the starch and protein reserves of the endosperm. The end products of this hydrolysis are absorbed by the scutellum and, after limited metabolism, transported to the growing regions of the embryo.
