| Abstract:
Non-destructive testing is important in the search for seed characteristics that relate to quality. It provides a means for consecutive testing on a seed by seed basis. If the tests are fast and can be automated they can form the basis for rapid new analysis methods or online sorting. X-ray analysis of tomato seeds enables us to predict seedling morphology. Acoustic analysis provides rapid physical assessment of seeds, which correlates with seed coat conditions. Both techniques can be automated and provide potential new sorting techniques. The X-ray technique provided us with some evidence for the origin of vigour differences in tomato seeds: morphological differences in seed embryos and the availability of endosperm proved to be crucial. | |
