resumo -A mangabeira (Hancornia speciosa Gomes) é uma árvore nativa do Brasil, cujo fruto é obtido predominantemente de forma extrativista e apreciado tanto in natura quanto na forma de polpas, geleias, doces. As raízes, cascas e látex possuem uso medicinal e sua madeira é usada como combustível. Ocorre do Nordeste até os Cerrados das regiões Centro-Oeste, Norte e Sudeste. Entende-se que estudos científicos sobre espécies nativas de base extrativista são essenciais a fim de subsidiar estratégias para a conservação da espécie. O presente trabalho objetivou analisar as publicações acadêmicas sobre a mangabeira disponíveis na plataforma de periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes), utilizando os princípios da bibliometria. As buscas aconteceram por meio das palavras chave: "mangaba", "mangabeira" e "Hancornia speciosa Gomes", o que resultou em 103 publicações sobre a espécie. Essas publicações foram classificadas de acordo com o ano, o tipo e o periódico de publicação; e, de acordo com o seu conteúdo, enquadradas nas áreas de conhecimento estabelecidas pela Capes. Após o enquadramento verificou-se que 40,8% das pesquisas estão relacionadas às Ciências Biológicas, 19,4% às Ciências de Alimentos, 13,6% às Ciências Agrárias, 10,7% às Ciências da Saúde, 7,8% às Ciências Multidisciplinares e 1,9% às Ciências Sociais Aplicadas. Constatou-se que há poucos estudos sobre aspectos socioeconômicos, ecológicos e culturais, o que indica a necessidade de mais estudos sob esses enfoques para subsidiar estratégias para a conservação da espécie.

Vigor tests are important mainly to identify differences associated to lots performance in field conditions. The objective of this study was to define the most appropriate tests to evaluate the crambe (Crambe abyssinica) seeds vigor. Seven seed lots of crambe were subjected to the standard germination (on the first and last count), germination speed index (GSI), primary root protrusion speed index (PRPSI), seedling length dry and weight seedling, water stress test using PEG 6000 at -0.2 MPa, electrical conductivity and cold test without soil. Crambe lots studied had germination percentages varying from 54 to 80.5%. The GSI, on the first count of water stress and electrical conductivity test ranked lots between two vigor classes The PRPSI, seedling length, seedling dry weight and last count of water stress tests were less sensitive to evaluate vigor for crambe seed. The cold test without soil and the first count of standard germination test were capable to dishtinguish lots more efficiently than the standard germination test on last count by ranking four of the seven seed lots studied.

Hancornia speciosa is the target of research on genetic diversity, ethnobotanical and medicinal studies. However, information on the genetic variability of populations associated with modeling the potential distribution in the state of Sergipe has not yet been performed. The objective of this study was to predict the potential occurrence of H. speciosa in areas of high use of their fruits. The maximum entropy method was used to detect the distribution patterns of H. speciosa in variable environments. The diversity of four natural populations, situated in areas of extractivist, was determined by ISSR molecular markers. The species occurs more densely in the coastal regions of Sergipe. The prediction of occurrence indicates that the species reduces areas of occurrence, mainly due to anthropic actions. It is suggested that the species needs public policies aimed at its conservation and the priority populations for conservation.

The application of modern and efficient techniques to access seed physical and physiological information has contributed to new advances in the agricultural sector. The objective of this study was to evaluate morphometric parameters obtained from the X-Ray analysis using crambe seeds harvested at different maturation stages and to relate them to seed physiological potential. Seeds harvested at different maturation stages were evaluated using X-Ray test, germination, first germination count, germination speed index, root protrusion velocity and accelerated aging. The Principal Components Analysis was applied to data collected. The results demonstrated that the X-Ray analysis allowed to visualize internal morphology of crambe seeds. Differences between seeds harvested at different maturation levels were observed. Correlations between physical variables were verified, such as seed area with germination (r = 0.96). The use of X-Ray analysis combined with semi-automated analysis is efficient to differentiate crambe seeds in different maturation stages. The morphometric parameters are related to the physiological quality of crambe seeds.

Storage of desiccation-tolerant seeds is one of the most effective germplasm conservation strategies; however, several species of tropical and subtropical humid forests have seeds that are sensitive to desiccation, and recalcitrant seeds, making conservation a challenge. Recalcitrant seeds deteriorate during storage due to high respiration rates and metabolic activity, and protocols employing osmoprotective solutions aim to minimize those effects to maintain seed viability for a more extended period. Hancornia speciosa, a fruit tree considered a priority for research in Brazil, is a desiccation-sensitive species. Thus, this study aimed to assess the physiological parameters of viability, vigor, and enzymatic activity of H. speciosa seeds stored in an osmoprotective solution. Germination percentage, water content, electrical conductivity, shoot, root, seedling length, peroxidase activity, and heat-resistant protein concentration were determined for seeds collected during summer and winter harvests. In addition, gene sequences were explored through gene ontology using Blast analysis to identify the biological and molecular processes associated with enzymatic action during storage. Summer-collected seeds performed better in viability and vigor and are recommended for storage in the osmoprotective solution. After being stored in the solution, seeds collected in the winter improved germination and vigor. H. speciosa seeds harvested in the summer or winter and stored in the osmoprotective solution remain viable for up to 90 days. Peroxidase and heat-resistant proteins are active; these enzymes' expression regulation should be investigated in future studies.
