High Throughput phenotyping

The high trhoughput area entirely equipped with conveyors comprises:

Automated precision cultivation

Controlled irrigation

An irrigation system individually controlled using scales in 4 units (total capacity of 1385 pots or RhizoTubes®). The randomization allowed by the automatic displacement also contributes to increase the accuracy by avoiding a too important border effect.

Climate characterisation

Capteurs climatiques

The 4PMI has more than 50 climate sensors that grid all the automated greenhouses. Several climatic variables are measured: temperature, incident light or relative humidity. The platform has the necessary tools to precisely characterize the growth environment of each plant grown in its automated greenhouses.

Shoot and root phenotyping

The platform has two types of root phenotyping cabin:

The RhizoCab® HR (high resolution) allows phenotyping of roots in RhizoTubes® up to 3600 dpi (7 microns) and is accessible for root phenotyping developments

RhizoCab® HD

The RhizoCab® HD (high throughput) allows the phenotyping of more than 1,300 pots or RhizoTubes® per day at a resolution of 600 dpi (42 microns).

Acquisition of images is performed for both RhizoCab® at three wavelengths (465, 525, 625 nm).

The images obtained are analyzed in order to measure different morphometric parameters of the shoots and roots such as the projected area, the height and width, the prospecting area and the total length of the plant.
