RHIZOTRON ET UTILISATIONS DE CELUI-CI.

摘要

The rhizotron (10) has an inner wall (12) coaxial with an external wall (13) and defining a root propagation space (11) intended to receive a substrate along with the external wall. An upper part of a housing (45) supports a seed independently from presence of the substrate within the space. The housing is in communication with the space. A supply system supplies liquid e.g. water or nutritive solution, to the space. The space comprises a set of zones including a liquid storage zone and a root propagation zone. The inner wall consists of a material chosen from a polymeric natural or synthetic material. The internal wall consists of a material of metal. An independent claim is also included for a method for determining a phenotypic characteristic of roots of plants.
