Purity techniques were evaluated to determine which one would result in the greatest effiency in determining purity for Andropogon gayanus L., Brachiaria decumbens Stapf. And Panicum maximum jacq. Germination, pure live seed and time were the parameters for determining the best technique. The partial Blowing Technique for A. gayanus and the Uniform Blowing technique for B. decumbens and P. maximum were effective giving higher germination and pure live seed and requiring less time. To determine effects of germination techniques, different substrates, top of paper towel, rolled paper towels in plastic boxes, filter paper in petri dishes, and soil in plastic boxes at ambient temperature were used. Germination of A. gayanus was low, and no statistical significance was found among all techniques. The first count can be made at seven days with the final count at 21 days. For B. decumbens the technique using soil was significantly superior. Even though International Seed Testing Association rules recommend 21 days, this can be extended to 28. Rolled paper towels appear to be an effective alternative germination technique for A. gayanus and B. decumbens. For P. maximum soil was significantly superior. Even though ISTA and Association of Official Seed Analysts recommend 28 days for germination, this could be reduced to 21. A. gayanus retained viability for at least 10 months in storage and dormancy was broken at six months. B. decumbens retained viability for at least 10 months in storage. Maximum germination occurred at four months of storage. P. maximum has prolonged dormancy, and any appreciable decrease in dormancy occurred after 10 months storage. Dormancy breaking treatments for A. gayanus, B. decumbens, and P. maximum were not effective. No recommendation can be made, and it appears that the passage of time is really the ideal method for breaking dormancy.
