Soft X-ray radiation (Grenz rays) has been used in the X-ray radiography of seeds.It is based on the principle that the different parts of the seed absorb X-rays to a slightly Dry Food Dispensers varying extent.Empty seeds and empty regions in the seeds appears as dark areas on the film.X-ray radiography Training Wheels without staining and X-ray contrast radiography were compared to study the stored seeds of Scots pine ( L.
).The results were compared with the results of germination in a Jacobsen germinator according to ISTA norms.Pinus sylvestris.
