Quality of Lolium multiflorum tetraploide seeds marketed in Santa Catarina
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 1
Abstract
In the southern region of Brazil, during the winter period ryegrass becomes essential for pasture formation. The use and commercialization of tetraploid ryegrass seeds has grown in relation to diploids, mainly due to the superior quality of their seeds. The objective of this work was to evaluate the quality of tetraploid ryegrass seeds commercialized in the State of Santa Catarina. Six plots of tetraploid ryegrass seeds of the Barjumbo cultivar from different commercial establishments in the State of Santa Catarina were used. Each batch of seed was obtained from official collection. Lots of seeds of the certified category were searched, being two lots from each producing country (Argentina, Brazil and Uruguay). The physical and physiological quality was evaluated from the physical purity tests, mass of one thousand seeds, germination test, first germination count, shoot and root length and dry mass of the area and root. The results show that 100% of the analyzed lots meet the legal standards of physical purity for the commercialization of seeds. For the germination test the results obtained are 27% higher than the legal standard. The plots of tetraploid ryegrass seeds commercialized in Santa Catarina were within the legal standards for the physical purity and germination tests, while the other criteria showed inferior performance when compared to the plots of Argentina and Uruguay.
