“…According Metcalfe & Chalk ,37 the presence of crystalline inclusions in plant leaves can be associated with an adaptive mechanism for greater capture of light and optimize the photosynthesis rate. In studies conducted by Azevedo and contributors, 49 characteristics similar to petiolule anatomy of S. mombin were found in the petiole of Schinus terebinthifolius (Anacardiaceae) as vascular bundles with collateral arrangement and the presence of secretory cavities well developed, generally associated to the phloem. The lumen of the ducts located in the phloem is also oval in cross section in young stems of Anacardium occidentale.…”

Background: Spondias mombin L. is fruit specie found in Tropical America and the coast of Africa, popularly known as cajazeira. Several researches with extract of leaflets show a diversity of promising pharmacological activities such as antibacterial activity, antiviral against dengue virus type 2, anti diabetic, among others. Objective: This paper aims to study the anatomical characteristics, phytochemical and histochemical from leaves of this species. Materials and Methods: Cross and paradermic sections from leaves were submitted to double staining with astra blue and safranin process for the anatomical study. Anatomical analysis of the structures was performed using an optical microscope. For ultra structure analysis, the leaf fragments, after processing and gold coating, were observed under scanning electron microscopy (SEM). The phytochemical analyses were performed using thin layer chromatography and the histochemical analyses using specific reagents for each metabolite group. Results: The leaf has anomocytic and tetracytic stomata distributed on abaxial surface. The midrib has convex symmetry with collateral vascular bundles in a closed arc disposition. The phytochemical showed the presence of mono and sesquiterpenes, triterpenes and steroids, hydrolysable tannins, phenylpropanoid glycosides, cinnamic derivatives and flavonoids. The histochemical tests allow us to state that phenolic compounds are found in the palisade parenchyma cells. Lignins can be found in woody vascular bundles and in perivascular sclerenchyma fibres. The volatile oils were evidenced in the schizogenous cavity, present in the parenchyma of the midrib. Conclusion: The results allowed characterizing anatomically the leaves of this species, outlining a profile of its phytochemical constituents and, in addition, determining which anatomical structures of storage of these metabolites by the plant.

“…For aroeira, results showed that levels of shading between 20 and 40% did not affect SLA. Aroeira are pioneer species, therefore, they are expected to tolerate full sunlight treatment (Azevedo, Quirino, & Bruno, 2015). Accordingly, plants subjected to 90% shade produced leaves with the greatest SLA values.…”

Studies of forest species under different environmental conditions are essential for enhancing our understanding of plant-environment relationships. Different light conditions interfere with the production of seedlings within forests, and this interference can be verified by assessing leaf area. However, several species have leaf compound that often contain numerous leaflets, which makes the direct measurement of leaf area difficult. This leads researchers to question whether these types of leaves should be separated for analysis or measured whole. Thus, the aim of this study was to analyse specific leaf area in whole leaves and detached leaflets of six forest species subjected to different levels of shading. The forest species assessed all produced compound leaves and included Schinus terebinthifolius Raddi (aroeira), Schinopsis brasiliensis Engl. (braúna), Dalbergia nigra (Vell.) Fr. All. ex Benth. (jacaranda-da-bahia), Chorisia speciosa A. St.-Hil (paineira), Caesalpinia peltophoroides Benth (sibipiruna) and Plathymenia reticulata Benth (vinhático). Each species was subjected to six different degrees of shading: 0% (full sun); 20; 40; 60; 80 and 90%. Sombrite netting was used to shade plants. The analysis of the specific leaf area was performed using two different methods, which included the analysis of separate leaflets and whole leaves. To analyse leaflet area,50 leaflets per plant were assessed three times, and six plants per treatment were assessed. To assess whole leaves, data were obtained from the whole leaves of six plants per treatment. This process was repeated for all aforementioned species. Data obtained from both analysis methods indicated that all species assessed were similarly affected by shade, and leaf area varied according to the level of shading. This similarity of data demonstrates that, for these species, it is not necessary to use complex methods to obtain specific leaf area measurements. Thus, determining specific leaf by measuring the entire leaf provides results that did not statistically differ from those obtained by measuring individual leaflets.

“…The present study provided a better understanding of the anatomy of the species and its behavior in relation to different luminous intensities, both in relation to leaf temperature (AZEVEDO, et al, 2015). Escolheu-se esta espécie para a pesquisa por ser nativa da região, e seus múltiplos usos ampliam a relevância da pesquisa para a comunidade em geral.…”
