METHOD FOR MODIFYING ROOT GROWTH

摘要

A method of modifying the growth of plant roots is provided in which the roo ts 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 such that moisture is released into the growing medium from the membrane whilst materials exuded from the plant roots are retained withi n the growing medium by the membrane, wherein the membrane is a hydrophobic porous membrane or a hydrophilic non-porous membrane.
