Paliavana tenuiflora é um arbusto com flores campanulares azul-violeta, com antese às 11:00 h, e duração das flores por aproximadamente seis dias. Grandes quantidades de néctar são produzidas (médias de volume 15,5µl, concentração 22,7% e teor de açúcar 5,0 mg µL-1). A produção de néctar não está relacionada com o período do dia, mas a concentração variou com o volume. A espécie é autocompatível, mas a formação de frutos depende de polinizadores. Apesar do néctar estar disponível de dia e de noite, P. tenuiflora se encaixa na síndrome de polinização por abelhas e, de fato, é polinizada por Bombus brevivillus. Entretanto, o beija-flor Phaethornis pretrei pode ser considerado polinizador ocasional, devido a seu comportamento e a baixa freqüência de visitas. Os resultados sugerem um sistema de polinização misto, porém a importância de P. pretrei como polinizador precisa ser mais bem avaliada.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-04-12T11:52:42Z No. of bitstreams: 1 __www.scielo.br_pdf_abb_v24n4_v24n4a12.pdf: 115208 bytes, checksum: 2c8895e47c3602f05b188613b02a6758 (MD5)Made available in DSpace on 2012-04-12T11:52:42Z (GMT).
