Hello David, we have worked on germinability on pine tree, beech and others. We used single seed as well as ground kernels. We had no success. We did try to differenciate for empty seeds, molded (?) seeds, insect infestation and regular filled seeds. We had success to detect empty seeds. From Lestander at Uppsalla there is a good report on detection of viable seeds vs. dead seeds. It uses the water permeability through the seed coating based on "old" polish (?) research. It does work, but is very teadious. Your question is put on the table frequently and I think most seed companies have tried to use NIR for the determintation of germinability. Since you can't find literature on this topic the answer to the question seems obvious for me. Keep in mind that for seeds from trees you are looking for germinability of 10-90% compared to germinability of seeds from agriucultural plants with most of the time of 90% and above. We had the simple task. Yours Peter Tillmann | ||

Hi, I tried to find info on whether anybody use NIR to test for germinability in seeds on a routine basis. (basically, what percentage of a seed sample is likely to germinate under controlled conditions). Can't really find any useful info using Google in this case. Thanks / David |
