-Queen palm is a tropical species of ecological importance and economic potential in various uses, including food. however, the knowledge about the nutritional value of fruits and the estimation of seed viability are still scarce. the aims of this work were to study the biometrics and chemical composition of fruits and seeds; describe the anatomy of embryos and assess the viability of the tetrazolium test. Mature fruits were collected, processed and submitted to biometry, water content, pulp and seeds chemical composition, germination and emergence in the laboratory evaluations. For the tetrazolium test, whole embryos were immersed in solution at 40 °c for one, two, four and six hours and compared with germination. the fruit pulp is rich in carbohydrates. the tetrazolium test performed at 40 ° c and 0.2% solution for two hours is adequate to estimate seed viability. Index terms: Queen palm, embryo; Germination; Palm. Pyrene. COMPOSIÇÃO QUÍMICA E TESTE DE TETRAZÓLIO EM SEMENTES DE Syagrus romanzoffiana (Cham.) GLASSMANRESUMO -O coqueiro-jerivá é uma espécie tropical de importância ecológica e potencial econômico em diversos usos, inclusive alimentício. contudo, o conhecimento sobre o valor nutricional dos frutos e a estimativa da viabilidade de sementes ainda são escassos na literatura. Os objetivos deste trabalho foram estudar a biometria e a composição centesimal de frutos e sementes; descrever a anatomia dos embriões, e avaliar o uso do teste de tetrazólio. Frutos maduros e recém-colhidos foram processados e submetidos à avaliação de dados biométricos, teor de água e composição química da polpa e das sementes, avaliação da germinação e emergência de plântulas em laboratório. Para o tetrazólio, embriões inteiros foram imersos na solução, a 40 °c, por uma, duas, quatro e seis horas, e comparados com teste de germinação e da emergência. A polpa dos frutos é rica em carboidratos.O teste de tetrazólio conduzido a 40°c, em solução de concentração a 0,2%, durante duas horas, é adequado para estimar a viabilidade das sementes.

“…Based on the information about the collection sites found on herbarium labels, species were assigned to one or more of the following habitat classes: forest interior, forest edges (interfaces between forests and open areas), rock outcrop vegetation, anthropogenic vegetation, and banana plantation. By consulting the literature (Ichaso 1980, Pennington et al 1981, Pennington 1990, Lorenzi 1998, Barroso et al 1999, Bovini et al 2001, Wanderley et al 2001, 2002, 2003, 2009, 2012, Mansano et al 2004, Passos & Oliveira 2004, Reis 2006, Souza & Morim 2008, Ferreira 2009, Gomes-Costa & Alves 2012, Silva-Luz et al 2012, Ferreira & Miotto 2013, Soares Neto et al 2014, specialists, and through examinations of material deposited at the RB Herbarium, the species of angiosperms were classified into four major groups according to the morphological criteria of Pijl (1982): 1) anemochoric, with diaspores adapted to wind dispersal; 2) zoochoric, with diaspores adapted to animal dispersal; 3) hydrochoric, with diaspores adapted to water dispersal; and 4) autochoric, with diaspores displaying no apparent specific adaptation to the above dispersal agents, including barochoric species (gravity dispersal) and those with explosive dispersal. By consulting the same aforementioned sources, we also determined which species are autochthonous to ombrophilous forests and/or pioneer formations (sensu IBGE 2012): beach ridge vegetation (restinga; Lacerda et al 1993) and rock outcrop vegetation (Meirelles et al 1999), of the Atlantic Forest complex in southeastern Brazil, and which species are associated with anthropically disturbed areas (ruderal species; sensu Moro et al 2012).…”

Studies of the vegetation on islands off the coast of southeastern Brazil are still very scarce, despite their importance for assessing, managing, and conserving insular biodiversity. We present here a list of the vascular flora of Queimada Grande Island (QGI; 24°29′10″ S, 46°40′30″ W, 57 ha, 33.2 km from the coast) in southeastern Brazil and describe its phytophysiognomies. The island is covered mainly by Atlantic Forest (Dense Ombrophilous Forest), as well as with rock outcrop and anthropogenic vegetation with herbaceous-shrub phytophysiognomies. QGI showed relatively low species richness (S = 125) when compared to other Brazilian coastal islands. Herbaceous (52) and climbing species (31) predominated on QGI. The richest families were Fabaceae (11 species), Poaceae (9), and Apocynaceae, Asteraceae and Orchidaceae (8 species each). Most species (S = 112) are autochthonous from different phytophysiognomies of the southeastern Brazilian Atlantic Forest complex. Many species associated with anthropically disturbed areas (S = 26) can be found on QGI, including the invasive grass Melinis minutiflora. There was a slight predominance of zoochory (S = 50). We did not identify any species endemic to QGI. One of its species (Cattleya intermedia, Orchidaceae) is vulnerable at both national and regional levels, and another (Barrosoa apiculata, Asteraceae) is presumably extinct on the mainland in São Paulo State. The vascular flora of QGI originated from the mainland Atlantic Forest complex, following the pattern of other coastal islands in southeastern Brazil. The flora and vegetation of QGI reflect the combination of insular conditions, the small size of the island, habitat restriction, steep topography, incipient soils, and the past use of the area with the introduction of several foreign species. We recommend permanent monitoring of the vegetation cover of QGI and its management, in order to ensure the conservation of the local native biota. Keywords: Atlantic Forest; biodiversity conservation; coastal islands; dispersal syndromes; invasive species; protected areas. Flora vascular e vegetação da Ilha Queimada Grande, São Paulo, sudeste do BrasilResumo: Estudos sobre a vegetação de ilhas costeiras no sudeste do Brasil ainda são muito escassos, apesar de sua importância para a avaliação, manejo e conservação da biodiversidade insular. Nós apresentamos aqui uma lista da flora vascular da Ilha Queimada Grande (IQG; 24°29′10″ S, 46°40′30″ W, 57 ha, 33,2 km da costa), sudeste do Brasil, e descrevemos suas fitofisionomias. A ilha é recoberta principalmente por Floresta Atlântica (Floresta Ombrófila Densa), bem como por vegetação sobre afloramento rochoso e vegetação antrópica com fisionomias herbáceo-arbustivas. A IQG apresentou riqueza relativamente baixa (S = 125) comparada a de outras ilhas costeiras do Brasil. Espécies herbáceas (52) e trepadeiras (31) predominaram na IQG. As famílias mais ricas foram Fabaceae (11 espécies), Poaceae (9), Apocynaceae, Asteraceae e Orchidaceae (8 espécies cada). A maioria das espéc...

“…We identified the cited plants in situ and ex situ with the aid of botanical literature (Lorenzi, 2010;Lorenzi et al, 2006;Reis, 2006) and consulting specialists. The taxonomy followed the APG II system (Lorenzi & Souza, 2008) and scientific nomenclature was verified by querying the TROPICOS online database.…”
