water stress response trait osmotic adjustment capacity The main role of osmotic adjustment in the plant is to assist in the maintenance of turgor and volume as organs lose water during desiccation, i.e. to provide dehydration tolerance. Often determined by relative water or the amount of solute accumulated at a given water potential. The ability of the plant to adust the osmotic potential under stress conditions.
