Resumo: One hundred and sixty two cultivars/lines of lowland rice (Oryza sativa L.) were evaluated under greenhouse conditions for salinity tolerance. Fourteen to eighteen days old rice seedlings were transplanted in a submerged soil treated with solution of NaCl in small trays. Salinity injure ratings were done on the basis of percent dead leaves after four weeks. Cultivars/lines were grouped into tolerant moderately tolerant, moderately susceptible and susceptible. Among the tested cultivars, 11% were found to be tolerant, 11% moderately tolerant, 17% moderately susceptible and 61% susceptible. Visible salinity toxicity symptoms and possible reasons of growth reduction due to salinity were discussed.

As plântulas foram transplantadas com idade entre quatorze e dezoito dias após a germinação, em solo submerso tratado com solução de NaCl, em bandejas de plástico. A avaliação das injúrias causadas pela salinidade foi feita com base na percentagem de folhas mortas, quatro semanas após o transplantio. As cultivares ou linhagens testadas foram agrupadas em tolerantes, moderadamente tolerantes, moderadamente susceptíveis e susceptíveis. Entre as cultivares testadas, 11% foram tolerantes, 11% moderadamente tolerantes, 17% moderadamente susceptíveis e 61% susceptíveis. Foram discutidos os sintomas visíveis de toxidez à salinidade e a possível causa de redução de crescimento causada pela salinidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFageria, Nand KumarBarbosa Filho, Morei PereiraGheyi, Hans Raj.2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17054Pesquisa Agropecuaria Brasileira; v.16, n.5, maio 1981; 677-681Pesquisa Agropecuária Brasileira; v.16, n.5, maio 1981; 677-6811678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17054/11378info:eu-repo/semantics/openAccess2014-04-15T19:42:27Zoai:ojs.seer.sct.embrapa.br:article/17054Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:42:27Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
