Abstract
A method of modifying the growth of plant roots is provided in which the roots are grown in proximity to a membrane from which water is released during the growth of the roots, wherein the membrane is a hydrophobic porous membrane or a hydrophilic non-porous membrane. The method may also be used to collect materials exuded from plant roots by growing the plant roots in a growing medium that is surrounded by a membrane so that moisture is released into the growing medium from the membrane while materials exuded from the plant roots are retained within the growing medium by the membrane, wherein the membrane is a hydrophobic porous membrane or a hydrophilic non-porous membrane.
