Vascular transport of auxins and cytokinins in Ricinus

  title={Vascular transport of auxins and cytokinins in Ricinus},
  author={Dennis Baker},
  journal={Plant Growth Regulation},
Analyses of vascular saps supplying source and sink organs havedemonstrated the presence of major endogenous hormones and/or theirprecursors. Indol-3yl-acetic acid, a number of gibberellins, cytokininsand abscisic acid, as well as the precursor for ethylene production havebeen found in these vascular saps, allowing the sites of hormonalsynthesis and putative target tissues to be deduced. Exogenously appliedhormones are also readily loaded into these vascular pathways and may betranslocated over… CONTINUE READING
