| ABSTRACT The quality of seeds is influenced by the climatic conditions of the production field. The identification of characteristics of the best forage seed fields allows the improvement of the sector. In this study, the aim was to identify climatic characteristics of producing regions that may affect the physical and physiological quality of Brachiaria brizantha cv. BRS 'Piatã' seeds. Seeds from 10 lots were evaluated for purity, other seeds, mass of a thousand seed, water content, germination, dormancy, emergence, seedling emergence in sand and seedling emergence in the field. Temperature and precipitation data of each production field from flowering to harvest were obtained. The means of treatments were compared by the Scott-Knott test at 5%... |
