RE SEARCH Speedy plant monitoring with new camera technology By using the MIPSLED camera, the researcher needs to carefully check that the young potato plants grow evenly in the jars. They should not touch each other during the shooting, because that would make it difficult for the camera to keep them apart. practical fact, for example, is that you need to use young plants for your measuring. At the time of the shots, they should be more or less of the same size. This means that, by using the camera, we need to carefully check that the young potato plants grow evenly in the jars. They should not touch each other during the shooting, because that would make it difficult for the camera to keep them apart. In addition, we must carefully compare the resistance data, which we have meanwhile gathered from many potato varieties; with the data we collect from the camera. Comparing these experiments under various different conditions is rather timeconsuming.’ Comparing 28 wild varieties at the same time The camera can already be used, however, for all kinds of research into the development and infection methods of various attackers, Vleeshouwers says. What the researchers already know is that, if you spray a potato plant with Phytophthora spores, most of these spores run off the leaf towards the edges. This is clearly shown by the camera. A good, comparative Phytophthora test has also been carried out with 28 different wild varieties. They were recorded all at once using the robot setup with the camera. ‘That gave a wonderful picture later on of the different resistances of the individual varieties.’ Colleagues of Vleeshouwer are currently also testing the camera for a study into the salt tolerance of the potato plant. ● Leo Hanse Commissioned by Wageningen University’s Plant Breeding department, a good comparative Phytophthora test has already been carried out with 28 different wild varieties. They were recorded all at once using the robot setup with the camera, Vivianne Vleeshouwers shows on her computer. Potato World 2011 • number 2 23 Pagina 22
