The evaluation of the uptake of 24-epibrassinolide (BR) in growing maize root segments by means of multiple-selected ion monitoring showed that BR is accumulated into the fresh tissue independently of energy supply, while the experiments performed with frozen-thawed roots show a large adsorption to cell structures. The adsorption is freely reversible in frozen-thawed roots, whereas 30% of BR taken up in fresh roots is irreversibly bound.

Abstract
The evaluation of the uptake of 24-epibrassinolide (BR) in growing maize root segments by means of multiple-selected ion monitoring showed that BR is accumulated into the fresh tissue independently of energy supply, while the experiments performed with frozen-thawed roots show a large adsorption to cell structures. The adsorption is freely reversible in frozen-thawed roots, whereas 30% of BR taken up in fresh roots is irreversibly bound.
