| Abstract: | This paper deals with the techniques used in taking photographs of twenty tree species seeds of Fagaceae family in a contrast and direct way and by applying soft x-ray apparatus. The optimum photographic voltage, electric current, exposure time, contrast materials, contrast concentration and contrast time of various tree species seeds have been found out, which can be u-sed as reference for production and research department of tree seed examination. |
