Resumo: | The heterogeneous light pattern in forest environments leads to specific morphological and physiological responses. However, anthropogenic pressures in areas such as Atlantic Forest and Cerrado are modifying the light availability, and consequently the forest community composition. The aim of this study was to investigate the plasticity of forest species Pimenta pseudocaryophyllus under full sunlight and shade conditions. P. pseudocaryophyllus showed typical shade plant phenotype, with higher net photosynthesis, transpiration, and chlorophyll a and b contents when cultivated under this condition. The decrease in net photosynthesis under full sunlight conditions is probably related to PSII photoinhibition. In addition, under full sunlight, reduced height, number of leaves, and specific leaf area was observed, while plants in shade increased these characteristics. P. pseudocaryophyllus did not show high morphological and physiological plasticity, which may be a maladaptive response. It was concluded that forest disturbances could compromise the occurrence and survival of P. pseudocaryophyllus. |
