Abstract

About a decade ago, Gustafsson (3) reported that the sensitivity of barley seeds to x-ray treatment was positively related to their moisture content. Sensitivity was measured by germination percentage and vigor of seedlings produced from treated seeds. However, Caldecott (1) recently has shown that barley seeds with a moisture percentage between 8 and 16 were more resistant to x-ray damage than those with either a lower or higher water content. These conflicting results probably are related to differences in methods used to temper the seeds by the two investigators. Gustafsson (3) soaked the seeds in water while Caldecott (1) placed them in desicators with different relative humidities. Metabolic activity and x-ray sensitivity of seed would be expected to be enhanced more by the first method. For a discussion of the physical significance of moisture content of seeds on x-ray sensitivity the reader is referred to a paper by Caldecott (2). This paper reports experiments conducted to determine the relationships between moisture content of seeds and x-ray sensitivity in hexaploid oats.
