title: Do growth substances regulate the phloem as well as the xylem transport of nutrients to the strawberry receptacle?
abstract: Fruits of first or second order of strawberry cv. Talisman were used for the experiments. Fourteen d after pollination they were deprived of achenes and the receptacles were treated for 3 d with a mixture of indoleacetic acid (IAA), gibberellic acid (GA3) and kinetin at a concentration of 3·10(-4) M. Then [(14)C]sucrose and (32)PO 4 (3-) were applied to the surface of the leaves or to the root medium. Only the transport from the leaves, not from roots, underwent hormonal stimulation; moreover, both markers were affected by the growth regulators to a similar degree.
