Resumo: | An experiment under greenhouse conditions was carried out at Universidade Federal de Lavras, Minas Gerais State, Brazil, to evaluate the growth of seedlings, phosphorus critical levels and phosphate fractions, in forest species growing under four phosphorus levels. Seedlings of Schinus terenbinthifolius Raddi (aroeirinha), Chorisia speciosa St. Hill. (paineira) and Syzygium jambolanum Lam. (jambolão) were cultivated on an Oxisol fertilized with 0, 150, 300 and 600 mg dm-3 of P. The seedlings were harvested 180 days after germination and analysed for P forms. In all levels of phosphorus addition, the paineira produced higher aerial and root biomass than aroeirinha and jambolão, and presented higher contents of organic phosphorus and higher relative participation of organic phosphorus in the total acid soluble phosphorus under all phosphorus levels. The improved growth rate of paineira was attributed to a greater efficiency in the metabolic adjustments of this species in relation to phosphorus nutrition, indicating that this species can grow in soils of variable P levels. |

Mudas de aroeirinha (Schinus terenbinthifolius Raddi), paineira (Chorisia speciosa St. Hill.) e jambolão (Syzygium jambolanum Lam.) foram cultivadas em um Latossolo Variação Una, onde foram aplicados 0, 150, 300 e 600 mg dm-3 de P. Aos 180 dias após a germinação, as plantas foram colhidas e submetidas às análises químicas. Sob todas as doses de P, a paineira produziu maior biomassa da parte aérea e das raízes em comparação à aroeirinha e jambolão, além de apresentar maiores teores de P orgânico (Po) e maior participação relativa do P orgânico (Po) em relação ao P total solúvel em ácido em todos os níveis de fertilização fosfatada. O melhor crescimento da paineira foi atribuído a uma maior eficiência nos ajustes metabólicos desta espécie em relação à nutrição fosfatada, o que indica que esta espécie pode ser plantada em solos com diferentes níveis de P.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFernandes, Luiz ArnaldoNeto, Antonio Eduardo FurtiniFonseca, Fernando CavicchioliVale, Fabiano Ribeiro do2000-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5885Pesquisa Agropecuaria Brasileira; v.35, n.6, jun. 2000; 1191-1198Pesquisa Agropecuária Brasileira; v.35, n.6, jun. 2000; 1191-11981678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5885/2989info:eu-repo/semantics/openAccess2014-08-19T16:10:46Zoai:ojs.seer.sct.embrapa.br:article/5885Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-19T16:10:46Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
