Resumo: Cotyledon persistence in seedlings grown under aluminum stress, previously found to be a good parameter to discriminate large differences In Al tolerance among Leucaena leucocephala (Lam.) de Wit. introductions, was evaluated as a method to discriminate different levels of tolerance between and within tolerant populations. Twelve single plant progenies obtained from three tolerant populations, one intolerant introduction and one single-plant introduction of unknown tolerance were screened in nutrient solution under 9 ppm of Al. Percentage of plants with yellowed or fallen cotyledons and total dry weight of the seedlings were recorded. The former parameter was efficient not only in the discrimination of tolerant versus intolerant populations, but also in the discrimination of different levels of tolerance within tolerant populations, contrasting in this respect with the latter parameter.

Para isto foram utilizadas doze progênies de plantas individuais referentes a três populações consideradas tolerantes, uma população intolerante e uma progênie de uma planta individual de tolerância desconhecida, cultivadas em solução nutritiva contendo 9 ppm de Al. Foram analisados os parâmetros percentagem de plântulas com cotilédones caídos ou amarelecidos e peso seco total das plântulas. O primeiro parâmetro foi capaz de discriminar não somente as populações tolerantes das intolerantes, mas também diferentes níveis de tolerância dentro de populações consideradas tolerantes, contrastando, neste aspecto, como segundo parâmetro.  Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMaluf, Angela MariaMartins, Paulo SoderoMaluf, Wilson Roberto2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15135Pesquisa Agropecuaria Brasileira; v.20, n.3, mar. 1985; 355-360Pesquisa Agropecuária Brasileira; v.20, n.3, mar. 1985; 355-3601678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15135/8919info:eu-repo/semantics/openAccess2014-04-17T11:47:55Zoai:ojs.seer.sct.embrapa.br:article/15135Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T11:47:55Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
