We worked through the night scanning samples. This morning we began the second experiment. For each sample a sweetcorn seed, which has been germinated - this means it had started to grow a root, is stuck to a plastic fitting using plaster of paris. The root is fed through a hole in the fitting so a little bit sticks out the end. A syringe barrel filled with soil is then attached to the fitting and the whole thing is put in the scanner. We are scanning the root every 6 minutes so we can see how it interacts with the soil particles as it grows.
So far the experiments have been running pretty smoothly and we have been seeing some good results.
