Resumo: | The ecophysiological behavior of plants is intrinsic to each plant species and is also influenced by environmental conditions such as solar radiation and water availability. Once the ecophysiology of tree species and their interactions with environmental conditions and their water use efficiency are better understood, local water dynamics can be better understood and more efficient management systems adopted. The objective of this study was to characterize, quantify and compare the ecophysiological behavior (transpiration, photosynthesis and stomatal conductance) and the efficiency of water use as a function of environmental variables and soil water availability of five native forest species: Croton urucurana, Cecropia pachystachya, Hevea brasiliensis, Gallesia integrifolia and Psidium cattleianum. The monitoring of the ecophysiological variables was performed in the hour scale, in healthy and expanded leaves of seedlings packaged with the aid of the diffusion porometer, and the leaf water potential was obtained by means of the Scholander pump. The results indicated that the studied species responded differently to environmental conditions (water availability, photosynthetically active radiation and vapor pressure deficit), and in general, the seedlings of all species under conditions of lower leaf water potential had lower rates of gas exchanges, however on a different scale of values. Thus, the restriction of water in the soil caused the plants to decrease their rates in order to avoid excessive water loss. |

Uma vez que se conhece melhor a ecofisiologia das espécies arbóreas e suas interações com as condições ambientais e também a sua eficiência do uso da água pode-se entender melhor a dinâmica hídrica da espécie. Sendo assim, este estudo teve como objetivo caracterizar, quantificar e comparar o comportamento ecofisiológico (transpiração, fotossíntese e condutância estomática) e a eficiência do uso da água em função de variáveis ambientais e disponibilidade hídrica do solo de cinco espécies florestais: Croton urucurana, Cecropia pachystachya, Hevea brasiliensis, Gallesia integrifolia e Psidium cattleianum. O monitoramento das variáveis ecofisiológicas foi realizado na escala horária, em folhas sadias e expandidas de mudas envasadas com auxílio de um analisador de gás infravermelho, sendo que o potencial hídrico foliar antemanhã foi obtido por meio da bomba de Scholander. Os resultados indicaram que as espécies estudadas responderam diferentemente às condições ambientais (disponibilidade hídrica, radiação fotossinteticamente ativa e déficit de pressão de vapor), sendo que de modo geral, as mudas de todas as espécies sob condições de menor potencial hídrico foliar apresentaram menores taxas de trocas gasosas, cada uma, no entanto em uma escala de valores diferente. Dessa forma a restrição de água no solo fez com que as plantas diminuíssem suas taxas a fim de evitar a perda excessiva de água.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)porUniversidade Federal de São CarlosCâmpus SorocabaPrograma de Pós-Graduação em Planejamento e Uso de Recursos Renováveis - PPGPUR-SoUFSCarAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessCondutância estomáticaFotossínteseTranspiraçãoPhotosynthesisStomatal conductanceTranspirationCIENCIAS AGRARIAS::RECURSOS FLORESTAIS E ENGENHARIA FLORESTALComportamento ecofisiológico de Croton urucurana Baill, Cecropia pachystachya Trécul, Gallesia integrifolia (Spreng.)

The results indicated that the studied species responded differently to environmental conditions (water availability, photosynthetically active radiation and vapor pressure deficit), and in general, the seedlings of all species under conditions of lower leaf water potential had lower rates of gas exchanges, however on a different scale of values.
