Resumo: | The reduction in water availability effects plant physiology and morphology and accounts for changes in metabolism with implications for the development of tree species. The objective of this study was to evaluate the influence of water stress on morphophysiological leaf characteristics and nutritional status of adult plant of gonçalo-alves (Astronium fraxinifolium), guanandi (Calophyllum brasiliense Cambess.), ipê-amarelo (Handroanthus serratifolius (Vahl.), ipê-rosa (Handroanthus impetiginosa (Mart.) Matos.), marupá (Simarouba amara Aubl.) and mogno (Swietenia macrophylla King.) cultivated under rainfed and irrigated conditions, in the irrigation perimeter of Baixo Acaraú, Ceará. The experimental design was a repeated measures, a scheme of sub-divided plots (6 x 2 x 2), the main plot consists of six species, the sub-plot of two water availability (irrigated and rainfed) and the sub-subplots were the evaluation time. The following evaluations were performed during the dry and rainy seasons: foliar concentrations of N, P, K and Na, specific leaf area (AFE), leaf succulence (GS), and relative index of chlorophyll (IRC). The results showed that ipê-amarelo was the most sensitive species in terms of variation of N, P and K concentrations in leaves in response to soil water availability. Regarding AFE, ipê-amarelo, ipê-rosa and mogno were more sensitive to extreme water deficit conditions. The water restriction in the soil causes the decrease of the leaf succulence in the gonçalo alves and mogno. The chlorophyll is directly affected by drought and is related to the higher GS and the lower AFE. As for A/N and A/P, gonçalo-alves was more efficient species, not affected by soil water availability conditions. |

O objetivo deste trabalho foi avaliar a influência do estresse hídrico no crescimento foliar e estado nutricional em plantas adultas de gonçalo-alves (Astronium fraxinifolium), guanandi (Calophyllum brasiliense Cambess.), ipê-amarelo (Handroanthus serratifolius (Vahl.), ipê-rosa (Handroanthus impetiginosa (Mart.) Matos.), marupá (Simarouba amara Aubl.) e mogno (Swietenia macrophylla King.), cultivadas em condições de sequeiro e irrigadas, no perímetro irrigado do Baixo Acaraú, Ceará. O delineamento experimental adotado foi o de medidas repetidas no tempo, num esquema de parcelas subsubdivididas (6 x 2 x 2), sendo a parcela principal composta por seis espécies, a subparcela por dois regimes hídricos (irrigado e sequeiro) e a subsubparcela pelas épocas de avaliação. Foram determinadas concentrações foliares de N, P e K, além de área foliar específica (AFE), grau de suculência (GS), índice relativo de clorofila (IRC) e eficiência fotossintética no uso de N (A/N) e P (A/P), nas estações seca e chuvosa. Os resultados mostraram que o ipê-amarelo foi a espécie mais sensível quanto à variação das concentrações de N, P e K nas folhas em resposta à disponibilidade de água no solo. Quanto à AFE, ipê-amarelo, ipê-rosa e mogno foram mais sensíveis às condições de déficit hídrico extremo. A restrição hídrica no solo ocasiona a diminuição da suculência foliar no gonçalo-alves e no mogno. O IRC é diretamente afetado pelo déficit hídrico e está relacionado ao maior GS e à menor AFE. Quanto a A/N e A/P, o gonçalo-alves foi a espécie mais eficiente, não sendo afetado pelas condições de disponibilidade hídrica do solo.Universidade Federal de Santa Maria2018-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3258110.5902/1980509832581Ciência Florestal; Vol. 28 No. 3 (2018); 924-936Ciência Florestal; v. 28 n. 3 (2018); 924-9361980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/32581/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessCampelo, David de HolandaLacerda, Claudivan Feitosa deSousa, João Alencar deBezerra, Antônio Marcos EsmeraldoAraújo, José Dionis MatosNeves, Antônia Leila RochaSousa, Carlos Henrique Carvalho2018-10-24T11:45:27Zoai:ojs.pkp.sfu.ca:article/32581Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-10-24T11:45:27Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
