“…In our study, only C. nucifera, Euterpe precatoria and Leopoldinia pulchra belong to the group of palm trees primarily pollinated by bees and, secondarily, by beetles (Listabarth 1996;Henderson et al 2000). The other genera, namely Astrocaryum, Bactris, Attalea, Mauritia and Elaeis, belong to the cantharophilic group, in which bees are secondary pollinators (Storti 1993;Henderson et al 2000;Tandon et al 2001). Regardless of Fig.…”

“…Moreover, species that usually grow spontaneously and are selectively removed by farmers, such as Cecropia, Sapium, Schefflera and Vismia, may also serve as pollen sources for bees if they are not eliminated. the effectiveness of bees as pollen vectors for palm trees, the abundance and constant supply of pollen throughout the year seems to make Arecaceae an especially important resource for Meliponini (Henderson 1986;Tomlinson 1990;Storti 1993;Henderson et al 2000). In a study of T. williana, eleven species of palm trees were recorded, with of the majority of them making pollen available for more than two months, including some species such as A. maripa and C. nucifera that were recorded in the pollen spectra for more than ten months (Marques-Souza et al 1996).…”

ABSTRACT. Pollen storages in nests of bees of the genera Partamona, Scaura and Trigona (Hymenoptera, Apidae). Bees and angiosperms established a mutualistic relationship along the evolutionary time. The aim of this study is to contribute for the understanding of this relation analyzing pollen stored by stingless bees colonies distributed along the Rio Negro. Fourteen species of Meliponini from the genera Partamona, Scaura, and Trigona were studied with regard to the content of pollen pots. The pollen material was removed from the pollen pots, homogenized, and prepared according to the usual acetolysis technique. The overlap of the trophic niche and the grouping of species by similarity of niches was calculated. The identification revealed 78 pollen types belonging to 36 families, being 37 types attractive and 16 considered as promoters of a temporary specialization event. With the results, it was possible to indicate a list of important plants for meliponiculture in the Amazon.KEYWORDS. Pollination, pollinic resource, stingless bee RESUMO. Pólen estocado nos ninhos de abelhas dos gêneros Partamona, Scaura e Trigona (Hymenoptera, Apidae). Abelhas e plantas estabeleceram ao longo do tempo evolutivo uma relação mutualística. Buscando contribuir para o entendimento dessa relação, foi analisado o pólen estocado por colônias de abelhas-sem-ferrão distribuídas ao longo do rio Negro. Foram estudados potes de pólen de 14 espécies de Meliponini dos gêneros Partamona, Scaura e Trigona. O material polínico foi retirado dos potes de pólen, homogeneizado e preparado segundo técnica usual de acetólise. Foram calculados a sobreposição de nicho trófico e o agrupamento das espécies pela similaridade de nichos. Foi identificado o total de 78 tipos polínicos, pertencentes a 36 famílias, sendo 37 destes, considerados atrativos, enquanto 16 foram promotores de eventos de especialização temporária. Com os resultados obtidos foi possível indicar uma lista de plantas de importância para a meliponicultura na Amazônia.PALAVRAS-CHAVE. Abelhas-sem-ferrão, polinização, recurso polínico.

“…These results are similar to those of the present study with A. vitrivir, which demonstrated continuous fruiting during 16 months, with fruiting alternating among different individuals. This pattern is not, however, standard among palm trees, as Storti (1993) described fruiting in the buriti palm (Mauritia flexuosa) to occur every two years and lasting for more than 12 months.…”

Do fruit morphology and scarification affect germination and predation rates of Babassu seeds?

et al. 2016

Seed predation is a natural phenomenon that can occur either before or after dispersal and can signifi cantly reduce the economic value and reproductive potential of plants. Th e babassu palm (Attalea vitrivir, Arecaceae) is important to rural communities that extract oil from its fruits for a wide variety of uses. We evaluated the predation and germination of A. vitrivirseeds in Pandeiros River Environmental Protection Area (EPA-Pandeiros) in Minas Gerais State, Brazil. Sixty individual plants were evaluated to determine their fruiting patterns. Seed predation and germination were evaluated in the natural environment for eight months for fruits divided into two treatments: scarifi ed and intact. Germination of fruits submitted to these same treatments was also evaluated under greenhouse conditions. Our results indicated that fruiting is continuous in this species and that fruit morphology does not infl uence either germination or predation. Likewise, fruit scarifi cation did not infl uence seed germination. Pachymerus cardo (Coleoptera: Chrysomelidae) preferentially oviposited on scarifi ed fruits, but only after their dispersal. Th e predation rate in the natural environment was 14.6%. Germination was not observed under natural conditions, but reached 33.05% under greenhouse conditions.

“…Entre as palmeiras mais utilizadas destaca-se Mauritia flexuosa L. f., conhecida popularmente como buriti, é encontrada no seu estado silvestre em várias formações vegetais, principalmente em áreas de inundação permanente ou periódica, em agrupamentos mais ou menos homogêneos, sobre solos hidromórficos, formando populações quase mono-específicas, às quais se dá o nome de miritizais ou buritizais (Storti, 1993;De Paula Fernandes, 2001). …”

RESUMOSão apresentados os dados anatômicos da epiderme dos segmentos foliares de Mauritia flexuosa L. f. (Arecaceae) em três fases do desenvolvimento. Os segmentos foliares foram analisados em toda a extensão do limbo. As células intercostais da epiderme das faces adaxial e abaxial evidenciam-se com paredes sinuosas, retangulares e orientadas longitudinalmente em relação ao eixo do segmento foliar com acentuada presença de corpos de sílica esférico-espinulosos. As células epidérmicas da região costal de ambas as faces apresentam paredes retas e variam entre curtas, longas e arredondadas. Os tricomas são simples, unicelulares, longos, com base mais alargada. Os segmentos foliares de M. flexuosa são anfiestomáticos com estômatos tetracíticos. Em secção transversal a epiderme foliar é uniestratificada com câmara subestomática ampla. Os resultados obtidos não demonstraram variações expressivas entre as três fases de desenvolvimento e os caracteres encontrados parecem ser comuns a outras palmeiras.
