Previous issue date: 2013-07-22 / CAPES / The objective of this study was to evaluate the imbibition and white lupine seeds physiological quality as affected by the pre-sowing treatments using immersion on the solutions with distinct micronutrients. The experimental design was conducted in a completely randomized in factorial (3 lots x 7 treatments) with four replications, by period of evaluation (start and after four months of storage). There were used three white lupine seed lots and seven distinct pre-sowing treatments (soaked or not soaked seeds on distilled water and in solution of boric acid (H3BO3), zinc sulphate (ZnSO4), manganese sulphate (MnSO4), copper sulphate (CuSO4), and molybdic acid (H2MoO4)). The seeds were evaluated to the imbibition and subsequently were submitted to the germination and vigor tests (first count of germination and electrical conductivity, dry weight and length of seedlings), as well the determinate of the seeds nutrients content. From the results it can be concluded that there was decreased speed of water absorption in the seed lot with lower physiological quality in the presence of manganese and molybdenum. Seed treatment by immersion in distilled water and in solutions of micronutrients favored physiological seed quality of three lots of white lupine. / O objetivo do trabalho foi avaliar a embebi??o e a qualidade fisiol?gica de sementes de tremo?o branco ap?s terem sido submetidas ao tratamento de pr?-semeadura por imers?o em solu??es de micronutrientes. O delineamento experimental adotado foi o inteiramente casualizado, em esquema fatorial (3 lotes x 7 tratamentos), com quatro repeti??es, por per?odo de avalia??o (inicial e ap?s quatro meses de armazenamento). Foram utilizados tr?s lotes de sementes de tremo?o branco e sete distintos tratamentos de pr?-semeadura (sementes imersas ou n?o em ?gua destilada e em solu??o contendo ?cido b?rico (H3BO3), sulfato de zinco (ZnSO4), sulfato de mangan?s (MnSO4), sulfato de cobre (CuSO4) e ?cido mol?bdico (H2MoO4)). As sementes foram avaliadas quanto ? embebi??o e, em seguida, submetidas aos testes de germina??o e de vigor (primeira contagem e condutividade el?trica, comprimento e massa de pl?ntulas) bem como ? avalia??o do teor de nutrientes. Pelos resultados pode-se concluir que houve diminui??o da velocidade de absor??o de ?gua nas sementes do lote com menor qualidade fisiol?gica inicial, na presen?a de mangan?s e molibd?nio. O tratamento de sementes via imers?o em ?gua destilada e em solu??es de micronutrientes favoreceu a qualidade fisiol?gica das sementes dos tr?s lotes de tremo?o branco.
