Osmóforos: Retrospectiva dos Últimos 20 Anos de Pesquisa1 1 Apoio CAPES

Resumo

Foram levantados os trabalhos produzidos nos últimos 20 anos de pesquisa em osmóforos, uma estrutura glandular floral envolvida na secreção de substâncias voláteis acompanhada, em muitos casos, de termogênese. As informações abrangem as tendências de pesquisa na estrutura e ultraestrutura anatômica da glândula, no perfil químico dos voláteis secretados, seu envolvimento na ecologia da polinização de angiospermas e nas respostas etológicas e eletrofisiológicas de insetos, induzidas pelos osmóforos e suas secreções.

Palavras chaves:
osmóforos; glândulas florais; voláteis florais; flores de perfume; polinização; pseudocópula; eletrofisiologia; Euglossini; Hymenoptera

Abstract

A survey of the last 20-year publications about osmophores is presented. Osmophores are floral scent glands which volatile secretion process is followed by heating in many of its types. Available data include trends in research about anatomical structure and ultrastructure of the gland, chemical constituents ofproduced volátiles, its role on pollination of angiosperms and ethological and electrophysiological responses of insects to osmophores and their secretion.

Key words:
osmophores; floral glands; floral scents; perfume flowers; pollination; pseudocopulation; electrophisiology; Euglossini; Hymenoptera
