Morfologia do polém de algumas compostas apícolas

Abstract

Apresentamos neste trabalho a descrição e estudos das características morfológicas dos grãos de pólem de 14 Compostas apícolas, mais frequentes nas análises polínicas de méis de abelhas, e do pólem coletado pelas abelhas Apis mellifera L., por nos verificados. Através do resultado das características de tamanho e forma do grão de pólem, do Amb (contorno do grão de pólem em Vista Polar), área polar, espessura da exina, comprimento dos espículos e número dos contornos em vista polar, pudemos elaborar uma Chave para identificação das espécies estudadas.

Melissopalynology in Brazil: a review of pollen analysis of honeys, propolis and pollen loads of bees

“…In relation to the pollen collected by bees, Santos (1964;1978) found sources similar to the pollen identified in honeys, while Cortopassi-Laurino & Ramalho (1988) reported Caesalpiniaceae, Cecropia, Eucalyptus, Mikania and Tipuana, and Marchini et al (2000), Arecaceae, Asteraceae (mainly Bidens sp. ), Eucalyptus sp., Mimosa caesalpiniaefolia, Ricinus communis and Zea mays.…”

“…Pioneer, traditional and standard studies in Melissopalynology (Louveaux et al 1970;1978) consolidated the development of reports on the occurrence of pollen grains in honeys, propolis and bee loads in Europe (France, Germany and Switzerland). The first investigations in Brazil were made by Santos (1961a;1961b;1963;1964) on pollen grains of bee plants and honeys collected in the region of Piracicaba, SP, followed by studies of Barth (1969;1970a;1970b;1970c;1971a;1971b;1973;1996) in different regions of the country.…”

“…Several publications were presented about the pollen collected by Meliponinae in the state of São Paulo (Kleinert-Giovannini & Imperatriz-Fonseca, 1987;Cortopassi-Laurino & Ramalho, 1988;Ramalho, 1990), as well as by Apis (Santos, 1964;1978), and the respective honeys (Santos, 1961b;1964;1978). In the region around the city of Belo Horizonte, MG, Bastos & Brandão (1994) investigated the vegetation for bees and performed pollinic and chemical analyses of honeys (Bastos, 1993), and also of the green propolis (Bastos, 2001;.…”

“…The first honey analyses of Apis were performed by Santos (1961b;1964;1978) in Piracicaba, State of São Paulo. The pollen spectrum was composed mainly by Eucalyptus, added by Agave sisalana, Baccharis, Dombeya and Persea.…”

“…Even though, various of these taxa were considered polliniferous, their pollen has no significant actrativity to be stored separately in the hives, and these plants were visited by the bees only as a nectar source. Data regarding this kind of information were obtained also for several regions of the state of São Paulo (Cortopassi-Laurino & Ramalho, 1988;Marchini et al, 2000;Moreti et al, 2002;Ramalho et al, 1991;Santos, 1961aSantos, , 1961bSantos, , 1964Santos, , 1978, Rondônia (Marques-Souza et al, 1993), and Roraima (Silva, 1998). The pollen morphology of plant species visited by Apis and Meliponinae in the South of Brazil consisted of a few families (Santos, 1997;Schlindwein, 1995;Wittmann & Schlindwein, 1995).…”
