Resumo: The aim of this work was to evaluate the influence of cashew (Anacardium occidentale L.) rootstocks on salt resistance in grafted plantlets. The plantlets were obtained by grafting the BRS 226 scion on CAPI 4, CCP 09 and BRS 226 rootstocks, and were exposed to nutrient solution without NaCl (control) or with 200 mM NaCl (salt treatment) in hydroponics under controlled temperature, humidity, and luminosity conditions during 12 days. The experimental design was a completely randomized in factorial arrangement 3x2 (three scion/rootstock combinations, two NaCl concentrations) with four replicates. Na+, Cl-, K+ and organic solute concentrations and toxicity symptoms on leaves were determined. Na+ and Cl- contents, the K+/Na+ ratio and the free amino acid and proline concentrations in leaves were directly related to the visual toxicity symptoms. The rootstocks were classified as sensitive (CAPI 4), intermediate (CCP 09), and resistant (BRS 226) to high salinity. This variation was a consequence of the rootstock influence on Na+ and Cl- partitioning.

As mudas foram obtidas pela enxertia do clone BRS 226 sobre os porta-enxertos CAPI 4, CCP 09 e BRS 226. Foram expostas a meio hidropônico sem NaCl (controle) ou com NaCl 200 mM (tratamento salino), sob condições controladas de temperatura, umidade e luminosidade, durante 12 dias. O delineamento foi o inteiramente casualizado, em esquema fatorial 3x2 (três combinações de enxerto/porta-enxerto e duas concentrações de NaCl), com quatro repetições. Foram determinados a concentração de Na+, Cl-, K+ e solutos orgânicos e os sintomas visuais de toxicidade nas folhas. Os conteúdos de Na+ e Cl-, a relação K+/Na+ e as concentrações de aminoácidos e de prolina livres nas folhas tiveram relação direta com os sintomas visuais de toxicidade. Os porta-enxertos CAPI 4, CCP 09 e BRS 226 foram classificados como sensível, intermediário e resistente à salinidade elevada, respectivamente. Essa variação foi decorrente da influência do porta-enxerto na partição do Na+ e do Cl-.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPq e FUNCAPFerreira-Silva, Sérgio LuizVoigt, Eduardo LuizViégas, Ricardo AlmeidaPaiva, João Rodrigues deSilveira, Joaquim Albenísio Gomes2010-11-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/1577Pesquisa Agropecuaria Brasileira; v.44, n.4, abr. 2009; 361-367Pesquisa Agropecuária Brasileira; v.44, n.4, abr. 2009; 361-3671678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/1577/5689https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1577/1056https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1577/1167info:eu-repo/semantics/openAccess2012-06-17T11:48:31Zoai:ojs.seer.sct.embrapa.br:article/1577Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:48:31Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
