INRA-CMI Roullier partnership: a new technology transfer

INRA-CMI Roullier partnership: a new technology transfer

Written by Groupe Roullier / published in Innovation

Two new arrivals came to strengthen the unique status of our phenotyping greenhouse during the summer. As a reminder, its role is to allow for non-destructive experiments with the use of a precision imaging system. 

Different types of cameras provide regular information on the morphology and physiology of the plants. 

RHIZOTUBE®, patented by INRA, allows us to monitor roots throughout their growth. Usually a highly tedious procedure, root monitoring with this equipment is automatic and makes it possible to compare, for example, the development kinetics of a biostimulated plant and a control plant. An internally developed image analysis programme makes it possible to distinguish the different parts of a root (main root, first- and second-order lateral roots, nodules, etc.). The CMI Roullier was the first private research centre to be equipped with this unique equipment. About sixty Rhizotubes have been put in service since the summer of 2017 for the development of new root biostimulants, and the study of phosphorus assimilation and the nodulation of leguminous plants. 

Another new arrival in the phenotyping greenhouse is a spray booth for experimentation with new biostimulants and liquid fertilisers. 

This booth has been completely outfitted according to the needs of the CMI Roullier and provides us the ability to standardise the applications of new products undergoing testing. The control system allows for a wide range of application conditions in order to meet our research requirements and facilitate translating those conditions to actual field conditions (TeeJet professional nozzles, movement during spraying, flow/pressure adjustment). Also, by confining stimulant application, this tool improves experimenter safety. With the use of this booth, the CMI Roullier proves once again the rigour with which the research teams carry out their work in order to identify new specificities and develop even more efficient products.
