| Abstract | Experiments were designed to reveal the accuracy and precision of four types of automatic sampler prototypes after initial testing indicated that the single tube vibrator sampler was not drawing a complete cross section of the seed flow in a vertical column. These experiments compared the automatic samplers with the trier types and methods used in the Oregon certification program. Samples were drawn from known closed populations of a ryegrass (Lolium perenne L.) seed lot and an alfalfa (Medicago sativa L.) seed lot. None of the automatic samplers or the trier samplers proved to be accurate or precise when sampling for all the contaminants in the two types of seed lots. The results of these experiments indicated that studies are necessary to further modify or redesign one or more of the sampling types in order to achieve a high degree of accuracy and precision in sampling a broad spectrum of grass and legume seed lots. |
