Resumo: Two wheat (Triticum aestivum L.) genotypes (CNT 10 and PAT 7392) were grown under two phosphorus levels (40 and 160 ppm P2O5) and four lime levels (zero, 1/4, 1/2 and 1 SMP). Plants were grown in greenhouse and phytotron with controlled temperature, light and humidity. Both root dry weight and length were evaluated and also the shoot weight. Aluminum or low phosphorus affected growth and differentiation, reducing root length and dry matter production and increasing the shoot: root ratio. A compensation effect between Al and P was observed and its effects were stronger on the roots and CNT 10 characterizing a germplasm more tolerant to Al than PAT 7392.

CNT 10 e PAT 7392 foram cultivados em baldes com solo Latossolo Vermelho Escuro álico, textura argilosa, sob duas concentrações de fósforo (40 e 160 ppm de P2O5) e quatro níveis de calcário (zero, 1/4, 1/2 e 1 SMP). As plantas foram mantidas em casa de vegetação e câmara de crescimento com temperatura, luz e umidade controladas. Na maturação, foram avaliados o comprimento e o peso seco das raízes, além do peso da parte aérea das plantas. Observou-se que a presença de alumínio tóxico ou baixa concentração de fósforo no solo afetou os processos de crescimento e diferenciação, reduzindo o comprimento das raízes e a produção de matéria seca e elevando a relação parte aérea/sistema radicular. Houve um efeito de compensação entre os dois elementos, com os efeitos se fazendo sentir mais acentuadamente sobre as raízes e CNT 10 caracterizando um germoplasma mais tolerante ao alumínio tóxico.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraZanatta, Ana Christina AlbuquerqueMundstock, Cláudio Mário2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14128Pesquisa Agropecuaria Brasileira; v.23, n.12, dez. 1988; 1355-1370Pesquisa Agropecuária Brasileira; v.23, n.12, dez. 1988; 1355-13701678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14128/8079info:eu-repo/semantics/openAccess2014-09-22T18:25:51Zoai:ojs.seer.sct.embrapa.br:article/14128Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-22T18:25:51Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
