“…Beltrati (1994) define arilo como excrescência do hilo ou do funículo, no entanto, Brasil (2009) usa o termo para qualquer excrescência carnosa da semente. Segundo Barroso et al (2004), esta estrutura é visualizada em diversas sementes do gênero Lecythidaceae, como encontrado para Eschweilera ovata, Cariniana legalis e Lecythis pisonis por Oliveira et al (2012), Ribeiro et al (2015) e Leão et al (2016), respectivamente.…”

“…De acordo com os resultados pode-se constatar que as sementes de inhaíba apresentam elevada variação em todas as dimensões avaliadas, gerando alto coeficiente de variação. Segundo Leão et al (2016), elevados coeficientes de variação podem ser decorrentes das condições genéticas das árvores matrizes e da interação dessas com diferentes condições edáficas e climáticas.…”

“…Estudos relacionados a aspectos morfológicos de frutos e sementes têm sido realizados para algumas espécies da família Lecythidaceae, tais como: jeniparana (Gustavia augusta L.), castanha-de-sapucaia (Bertholletia excelsa Humboldt & Bonpland); jequitibárosa (Cariniana legalis (Mart.) Kuntze) e Lecythis pisonis Cambess (Santos et al, 2006;Silva et al, 2014;Ribeiro et al, 2015;Leão et al, 2016).…”

O objetivo deste trabalho foi descrever os caracteres morfológicos de frutos e sementes de Lecythis lurida (Miers) S.A. Mori. Os frutos foram coletados no munícipio de Laje – Bahia em abril de 2018. No estudo do fruto, foram observadas as características: tipo, dimensões, textura, consistência do pericarpo e número de sementes por fruto. Os aspectos observados para as sementes foram: externas - cor, forma, dimensões, textura e consistência do tegumento; internas - embrião (cotilédones, eixo hipocótilo-radícula). O fruto de inhaíba é do tipo pixídio, indeiscente, de textura lenhosa, apresentando em média quatro sementes por fruto, com comprimento médio de5,61 cm e largura média de7,48 cm. As sementes apresentam formato triangular anguloso, tegumento ósseo, dotadas de arilo carnoso na região basal e ápice umbonado, com dimensões médias de 43,55 x 36,89 x29,28 mm. O embrião é conferruminado, sem distinção de cotilédones, eixo hipocótilo-radícula e plúmula. A morfologia de frutos e sementes fornece subsídios que contribuem para o reconhecimento da espécie.

“…It is necessary to perform research into native forest species to ascertain their potential to contribute to regional economies, as well as their possible suitability in projects to restore degraded areas. The knowledge gained can be used for the development of concepts for the utilization as crop plants which are aimed at improving nutrition and economical status of local, nature conservation, enable improving of local communities and also identify possible industrial uses (Carvalho, 2008;Leã o, Araújo, Shimizu, & Felipe, 2016).…”

The Amazon region contains the world’s leading genetic reserve of native plants, with most of the area located in Brazil. This region is rich in species that little known or still unknown by the population at large, including species that produce non-timber forest products (NTFPs) such as edible nuts. The objective was to verify the occurrence of these edible nuts in Brazil, to evaluate their potential and the possibility of other uses, in addition to expanding the knowledge about them. A bibliographic review of the last 50 years was carried out, mainly using the descriptors the popular name and the scientific name of the four nut trees present in the Amazon and their respective families, namely: agouti nut (Acioa edulis Prance) and egg nut (Acioa longipendula Pilg.) From the Chrysobalanaceae family, and sapucaia nut (Lecythis Pisonis Miers) and Brazil nut (Bertholletia excels Bonpl.) From the Lecythidaceae family. The Chrysobalanaceae has 450 species and 17 genera of woody plants and shrubs, producing oilseeds by some species, including egg and agouti nuts. The Lecythidaceae, on the other hand, has approximately 17 genera and 300 species, and in Brazil it is possible to find 9 genera and 122 species, 54 of them endemic, some of which produce edible seeds such as sapucaia and Brazil nuts. Those species have a great nutritional potential, and the chemical composition of their nuts reveals a good amount of lipids and proteins, but more in-depth research on the subject is necessary, including on other biases for better knowledge of the species, discovery of other potential uses and benefits and, consequently, their valorization.

“…Increased demand for native seeds for ecological restoration and rehabilitation has stood out in the large global industry of seed supply and sale (Smiderle et al, 2021). Therefore, research with native forest seeds is essential for obtaining seedlings of high quality and in quantities that meet the demands of the forestry sector segments (Leão et al, 2016), as seed propagation is the main form of dissemination of species and the study of seed technology and production becomes of great relevance in the process of management, conservation and genetic improvement (Menegatti et al, 2019).…”

The aim of this study was to establish a methodology to determine physiological vigor in small and large seeds of Hymenaea courbaril L. non-scarified seeds and scarified by the electrical conductivity test and period of seed soaking in water aiming at maximum capacity of emergence and seedling vigor. The design was completely randomized, in a 2 x 2 x 5 factorial scheme (two classes of seed mass, non-scarified seeds and scarified and five periods of soaking in water), with 10 replicates of 10 seeds each. The variables evaluated were electrical conductivity (μS cm-1.g-1), emergence speed (index), seedling emergence (%) and mean time of emergence (days), obtained by means of daily counts until stabilization in the values. Maximum vigor of Hymenaea courbaril seedlings is obtained with large seeds subjected to scarification and soaked in water for six hours. Water content of 18.7% in large seeds of Hymenaea courbaril scarified promotes the production of 100% of vigorous seedlings. Small and large seeds of Hymenaea courbaril non-scarified seeds and scarified, soaked for six hours, had shorter mean time for seedling emergence. Water content of 20.6% in small seeds of Hymenaea courbaril scarified promotes 100% seedling emergence. The electrical conductivity test applied to Hymenaea courbaril seeds can be adopted to determine seed vigor, showing speed in the obtaining of results and ease of execution.
