Plant Material. Growing conditions and treatment of plant material has been described elsewhere for the aquatic weed, Egeria densa PLANCH., in (6), Vicia faba L. in (2), Commelina communis L. in (7) and Cyclamen persicum MILL, in (5). 

Sucrose Absorption by Vascular Bundles. Sucrose uptake into 2-4 mm long pieces of vascular bundles isolated from the petiole of Cyclamen persicum was described in detail in (5). Briefly, the tissue material was preincubated (30 min) with brassinosteroids or related compounds, which were also present during the following incubation with 1 mM 1AC-labelled sucrose (30 min). All solutions contained 1 mM CaSO, 1 mM KC1 and 10 mM morpholinoethanesulfonic acid and were adjusted with NaOH to pH 5.0. After a 5-min-washing procedure and extraction in methanol the uptake rate for sucrose was determined analogously to the experiments with leaves.
