Closed rhizosphere system for subcultivation of paulownia microclones

Abstract

The utility model relates to the field of biotechnology, plant growing and agricultural technologies and is intended for the subcultivation of microclones of plants of the genus Paulownia in closed rhizosphere conditions. The system includes a container with a sealed lid, adjustable ventilation holes, a drainage layer, a humidity maintenance segment and a multi-component sterilized substrate containing high-moor peat, perlite, vermiculite and biochar. The use of the system ensures the formation of a controlled microclimate in the root zone of plants, reducing the stress load when transferring microclones from in vitro to ex vitro conditions, Improving root system development and increasing plant survival. The technical result of this utility model is to increase the efficiency of subculturing microclones of Paulownia plants by creating a controlled, closed rhizosphere with regulated gas exchange and stabilized substrate moisture.
