- Abstract
The aimed of this study was to evaluate the physiological quality of lots of seeds Brachiaria brizantha (Hochst) Stapf cv. BRS Piata in different tests for breaking dormancy and verify the adequacy of the legal attributes lots of marketing of seeds. Conducted at the UFSM Campus Frederico Westphalen, in a randomized block design arranged in a factorial five (lots of seeds Brachiaria brizantha cv BRS Piatã) x two (with or without breaking dormancy), arranged in four replications. Physically analyzing the different batches studied four are adjusted to Brazilian legislation for the minimum purity of 60%, however reflected in low cultural value due to the low germination expressed in certain batches. When checking physiological quality germination tests and force show variation depending on the lots, however express different answers to the treatments employed. In general highlights the cold test as a condition for overcoming dormancy, the same can be observed for the accelerated aging for most lots. To overcome dormancy there is a potassium nitrate efficiency, with positive responses to seed germination in field conditions, accelerated aging and cold test.
