Jülich Plant Phenotyping Centre (JPPC)

Data Acquisition

Imaging Pulse Amplitude Modulated Fluorometry (PAM) device moved by a xy-positioning system across a population of plants in pots, trays or petri dishes. The blue light results from the fluorimeters’ saturation pulse.

Determination of chlorophyll-fluorescence images by PAM light protocoll.

Image Analysis

• segmentation of fluorescent areas
• analysis of projected area and chlorophyll-fluorescence parameters

Example of results

• growth analysis based on fluorescent pixels
• chlorophyll-fluorescence analysis

F_V/F_m-values
The graph shows colour-coded images of plants under normal conditions (left), drought (centre) and cold stress (right). Light blue to green colouration indicates low, dark-blue to violet indicates high values.
