O objetivo deste trabalho foi examinar e documentar a biologia floral e os polinizadores da candeia (Eremanthus erythropappus) em uma população natural, sendo estudados a antese, a morfologia floral, a receptividade estigmática, a viabilidade de pólen e os visitantes florais. As flores pequenas (10,17 mm de comprimento) são cor de rosa, hermafroditas e organizadas em densos capítulos (média = 29 flores). Foi observada alta porcentagem de pólen viável (77,25%) e relativamente pouca disponibilidade de néctar para os visitantes florais (0,63 μL). As abelhas Apis mellifera e Trigona sp. foram os visitantes mais frequentes. Os comprimentos dos botões, estiletes e flores variaram significativamente entre plantas. [ABSTRACT FROM AUTHOR]
Floral biology and pollinators of candeia (Eremanthus erythropappus) were analyzed in a natural population. We studied anthesis, flower morphology, stigmatic receptivity, pollen viability and floral visitors. The small flowers (10.17 mm in length) are pink, hermaphrodites and organized in dense capitula (mean = 29 flowers). We observed a large percentage of viable pollen (77.25%) and relatively scarce nectar availability for floral visitors (0.63 μL). The bees Apis mellifera and Trigona sp. were the most frequent visitors. The length of the bud, style and flowers varied significantly among plants. [ABSTRACT FROM AUTHOR]
