Using MRI to study tomato fruit
International audience NMR Imaging (MRI) is an appropriate technique for studying of internal structure and dynamics of water in plant tissues. Because of its non-invasive and non-destructive character, MRI allows to make repetitive measures of the same sample and can thus be applied to monitor proc...
