“…Bertholletia excelsa e Eschweilera ovata Mart. ex Miers, que são do tipo criptocotiledonar (Santos et al, 2006;Oliveira et al, 2012), o que evidencia uma variação quanto aos tipos de germinação apresentados nesta família.…”

Gustavia augusta L., conhecida popularmente como jeniparana, é uma espécie arbórea neotropical, que ocorre nas florestas Atlântica e Amazônica. Considerando-se a abundância dessa espécie na floresta Atlântica e a fragilidade e fragmentação desse ecossistema, objetivou-se, com este trabalho, caracterizar seus frutos, sementes, germinação e plântulas, acrescentando informações para subsidiar estudos sobre sua conservação e utilização. Os frutos maduros foram coletados em fragmentos de floresta Atlântica, no município de Paulista, PE. Em seguida, foram realizadas análises morfológicas e biométricas dos frutos, sementes e plântulas da espécie. O fruto de G. augusta é um pixídio globoso, anfissarcídio, pentalocular, indeiscente. A semente é exalbuminosa, estenospérmica, trisseriada, bitegumentada e a massa de cem sementes desse lote foi de 47,95 g. A germinação da espécie é do tipo hipógea, com o tegumento aderido aos cotilédones na fase inicial do crescimento da plântula, que tem início a partir do quinto dia após a semeadura, em condições de laboratório. O tempo médio e o índice de velocidade de germinação (IVG) foram de 14 dias e 0,87, respectivamente. A plântula com 40 dias apresenta todas as estruturas, sendo classificada no tipo morfofuncional fanerohipógeo-armazenador (PHR).

“…Its nuts are an important source of calories (average: 736.87 kcal/100 g), are rich in calcium, phosphorus, and manganese, and can be consumed by humans and animals as a source of lipids and proteins (Souza et al, 2008). Several parts of the plant have been used in popular medicine, and recent studies have revealed the presence of compounds that have moderate cytotoxic activity (Silva et al, 2012). This plant is used in the wood industry, in the production of cosmetics, for ornamental cultivation, and in the production of handmade objects (Revilla, 2002).…”

ABSTRACT. Sapucaia is a tree species originating from the Brazilian Amazon and is widely distributed in Brazil, especially in the mid-north region (Piauí and Maranhão states). Its seeds are rich in calories and proteins, and possess great potential for commercialization. Little is known about the genetic variability in the germplasm of most Lecythis species. Here, 11 inter-simple sequence repeat primers were used to estimate the genetic variability among 17 accessions, and to determine the levels of genetic variation and the standards of population structure in sapucaia. The accessions were obtained from the active germplasm bank (AGB) of Embrapa Meio-Norte, Teresina, PI, Brazil, and corresponded to four occurrence areas. Ninety-six loci were analyzed 2 R.C. Borges et al. Genetics and Molecular Research 15 (3): gmr.15038565 among the studied individuals. High variation was found at the species level, where the percentage of polymorphic bands was 94.79%, Nei's genetic diversity (h) was 0.3110, and Shannon's index (I) was 0.4732. In the analyzed populations, the percentage polymorphism ranged from 20.83 to 94.79%, Nei's genetic diversity ranged from 0.0863 to 0.2969, and Shannon's index ranged from 0.1260 to 0.4457. Significant genetic differentiation was detected among the populations (Φ ST = 10.66%); however, the greatest genetic differentiation was found within the populations (89.34%), between which there was an intermediate level of gene flow (N m = 1.10). Accessions BGS 2 and BGS 4 were the most divergent, whereas accessions BGS 14 and BGS 15 were the most similar. Therefore, sapucaia analyzed from the AGB present an elevated level of genetic diversity and may have potential use in genetic breeding programs.

“…Traditionally, the infusion prepared from the bark of the tree is astringent and used in the treatment of diarrhea, while the leaves are used as diuretic and tonicardiac in tea or infusion or in baths to relieve itching (pruritus) and the fruits are used in the treatment of diarrhea and syphilis (Braga et al 2007;Denadai, 2006). The phytochemical study of the leaves of this species led to the isolation of pentacyclic triterpenoids, phytol, sitosterol and stigmasterol (Oliveira et al, 2012). The ethanol extract and the mixture of ursolic and oleanolic acids obtained from the leaves demonstrated antipruritic and cytotoxic activities (Silva et al, 2012;Oliveira et al, 2012).…”

Phytochemical investigation of the ethanol extract of leaves, twigs and fruit shell of Lecythis pisonis Camb. revealed the presence of squalene, -e -amyrin, lupeol, 3-friedelinol, ursolic and oleanolic acids, (E)-phytol, sitosterol, stigmasterol, campesterol, quercetin-3-O-rutinoside and kaempferol-3-Orustinoside. Structural elucidation was achieved using ultraviolet (UV), nuclear magnetic resonance (NMR), and mass spectrometry. This is the first report of the occurrence of flavonoids, together with squalene, lupeol and campesterol in L. pisonis. The EtOH extract of the leaves showed high antioxidant activity, which can be associated in part with the high level of phenols and flavonoids.
