In this example two batches of soybean are being germinated. The left batch is of poor quality, contains a lot of so called ‘green seeds’, seeds which are not fully mature. Using the CropReporter technology the images show that these seeds have already in dry state a high chlorophyll fluorescence signal. The right batch is of high quality, these seeds have in dry state a low fluorescence signal. When the water uptake starts, the fluorescence signals of the seeds of high quality increases, indicating methabolic activity. At a certain level of fluorescence the seeds germinate. The colors used indicate the level of fluorescence signal, low to high: black-red-orange-yellow-green.
