Resumo: The objective of this study was to identify iron concentration and the plant most important character to study rice genotypes tolerance to iron toxicity. A hydroponic culture experiment was carried out to evaluate 20 rice genotypes and 10, 20, 40 and 80 mg L-1 of iron concentration. Growth characters evaluated were: root length, root, canopy and total dry matter, and plant height. The seedlings were grown for 10 days in nutrient solution and 20 mg L-1 of Fe was found to be ideal for such study. Total plant dry matter was the most adequate parameter for such study due to its higher relative contribution in genetic variation of the genotypes evaluated.

Realizou-se o cultivo hidropônico de 20 genótipos desta cultura, crescidos coletivamente em caixas, nas concentrações de 10, 20, 40 e 80 mg L-1 de ferro. Foram avaliados os caracteres comprimento da raiz, massa da matéria seca da raiz, da parte aérea e total, e altura da planta. Após dez dias de crescimento em solução nutritiva, identificou-se, com base em técnicas uni e multivariadas, a concentração de 20 mg L-1 de ferro como a ideal para estudos genéticos em arroz, e o caráter massa da matéria seca total foi o que teve maior participação na contribuição relativa para a divergência genética entre os diversos genótipos de arroz estudados.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFerreira, Reinaldo de PaulaCruz, Cosme DamiãoFageria, Nand Kumar1997-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4765Pesquisa Agropecuaria Brasileira; v.32, n.11, nov. 1997; 1177-1182Pesquisa Agropecuária Brasileira; v.32, n.11, nov. 1997; 1177-11821678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4765/7272info:eu-repo/semantics/openAccess2015-04-17T17:45:52Zoai:ojs.seer.sct.embrapa.br:article/4765Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-04-17T17:45:52Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
