| Abstract: | This paper deals with the techniques of radiographing Pinus elliottii and other 19 tree species seeds in a contrast as well as a direct way by applying a soft X-ray apparatus.The optimum radiographic voltage, electric current, exposture time, contrast materials, contrast concentration and contrast time for each tree species seed have been found out along with different film distance and different photosensitive materials. |
