Whilst the water uptake isotherms confirmed the high
capacity of the beads compared with silica gel, particularly at low relative humidity, the beads do not work to
full capacity in a bead-seed system and the adsorption properties appeared to change. Further work is required
to optimise the use of these beads for drying seeds to target moisture contents, without either under-drying
which could lead to undesirable high rates of viability loss, or unnecessary and perhaps detrimental over-drying.
