摘要
由于杂草和入侵植物生长在受干扰的生境中,它们应该具有有趣的繁殖策略,因此研究它们的繁殖生物学对它们的管理和控制具有重要意义。本文在巴西巴伊亚州的大西洋森林城市片段中,分析了解剖Merremia dissecta var. edentada的花卉生物学和生殖系统的各个方面。沙锥花是一种草本藤本植物,花嗜石,连续开花结果。它的白花是短暂的,每天开花,提供花粉和花蜜作为花的资源。该物种具有自交亲和性,主要由蜜蜂访问,Trigona是它们潜在的传粉者。该物种表现出与植物物种相似的生殖特征,这些物种通常发生在受干扰的栖息地,并改变了花访问者的动物群。关键词:菊科,蜜蜂,短命花,Trigona,藤本植物
Biologia floral e polinização de Merremia dissecta var. edentada (Meisn.) O’Donell (Convolvulaceae) em um fragmento urbano de Mata Atlântica, Bahia
Since they occur in disturbed habitats, weeds and invasive plant species should have interesting reproductive strategies and, therefore, studies of their reproductive biology are important for their management and control. Here, aspects of the floral biology and reproductive system of Merremia dissecta var. edentada are analyzed in an Atlantic Forest urban fragment in the Brazilian state of Bahia. Merremia dissecta var. edentada is an herbaceous vine with mellitophilous flowers, with continuous flowering and fructification. Its white flowers are ephemeral, presenting diurnal anthesis and offering pollen and nectar as floral resources. The species is self-compatible and was mainly visited by bees, with Trigona spp. being their potential pollinators. The species presents reproductive traits similar to plant species that commonly occur in disturbed habitats with altered faunas of flower visitors.
Keywords: Apoidea, bees, ephemeral flowers, Trigona, vines.
