Summary X-RAYING AND ANALYSIS OF FOREST SEEDS The paper was prepared with the aim to indicate the possibility of using roentgenography in the examination of various different anatomical and physiological characteristics of forest seeds. In part one the roentgenographs technique is described, and the characteristics of radiographic film of various manufacturers are comparatively presented. Suggested is the possibility of using home-made industrial radiographic film Terix F in controlling the quality of forest seeds. In part two are discussed a number of more important investigations carried out by X-ray analysis of forest seed. |
