Abstract/Contents:"The efficiency of the vacuum counter as a sampling instrument was examined by removing successive 100-seed samples from half-working samples of pure seed of meadow fescue, cocksfoot and Brassica spp. until the pure seed sample was exhausted. The weight of 100 seeds was plotted against the number of samples taken and in many cases a significant relationship was found between 100 seed weight and sample number indicating a marked tendency for lighter seeds to be removed before the heavier seeds. In some cases this could lead to biased germination results. Although there is evidence that the vacuum counter may not be an entirely satisfactory sampling instrument there is no evidence to suggest that it is any worse than other methods of preparing germination replicates prescribed in ISTA rules."
