DescriptionThe study of internal seed structure by radiography requires techniques which will give good definition. To establish the best procedures, we conducted a series of experiments in which we manipulated the principal controllable variables affecting the quality of X-radiographs: namely, focus-to-film distance, film speed (grain), exposure time, kilovoltage, and milliamperage. The results presented here will eliminate the need for repetition by others interested in moving directly to research applications of X-radiography. A few examples will illustrate the interpretation of detail and perhaps suggest how radiographs can contribute to an understanding of the biology of seed formation.
