Resumo: | The white oat is a winter crop used in succession to rice cultivation, subject to salt stress due to the accumulation of salts in the soil, especially in the southern Rio Grande do Sul. The objective of this work was to evaluate the seed germination, initial growth of the nine genotypes seedling of white oat and to identify contrasting genotypes, well as to identify the genotypes contrasting to character for salt tolerance character. For this, the genotypes were submitted to different salt concentrations (0, 25, 50, 75 and 100 mM de NaCl per liter of water), being analyzed the following variables: percentage of germination, first counting germination, index germination speed, length, shoots and roots dry mass of seedlings. The results may imply that seed germination that the percentage of germination was slightly decreased compared to the shoot growth and roots that have been greatly reduced with increasing salt concentrations. The root length and shoot length is in promising variables in the separation of genotypes in relation to different salt concentrations, allowing you to select two contrasting genotypes to salinity, the (URS 22) characterized as tolerant and (UPF 16) as sensitive. |

O objetivo deste trabalho foi avaliar a germinação de sementes, o crescimento inicial das plântulas de nove genótipos de aveia branca, bem como identificar os genótipos contrastantes para o caráter tolerância à salinidade. Para isso, os genótipos foram submetidos a diferentes concentrações salinas (0, 25, 50, 75 e 100 mM de NaCl por litro de água), sendo analisadas as seguintes variáveis: porcentagem de germinação, primeira contagem de germinação, índice de velocidade de germinação, comprimento e massa seca da parte aérea e raízes das plântulas. As variáveis analisadas foram afetadas negativamente com o aumento da concentração de NaCl. O comprimento de raiz e o comprimento de parte aérea constitui em variáveis promissoras na separação dos genótipos em relação às diferentes concentrações salinas, permitindo selecionar dois genótipos contrastantes à salinidade, o URS 22 caracterizado como tolerante e o UPF 16 como sensível.UEL2015-10-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa científicaPesquisa científicaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1690710.5433/1679-0359.2015v36n5p2987Semina: Ciências Agrárias; Vol. 36 No. 5 (2015); 2987-3000Semina: Ciências Agrárias; v. 36 n. 5 (2015); 2987-30001679-03591676-546Xreponame:Semina.
