Floral biology of Agave gentryi ullrich (Agavaceae) in the locality of La Marcela, in Miquihuana, Tamaulipas

Abstract

The study focused on the Agave gentryi kind with quiropterófilo pollination. The goal was to characterize the floral biology of the Agave gentryi kind in La Marcela, Miqihuana, Tamaulipas. The hypothesis that says that if most of the Agave kind plants are pollinated by quiropteros, then the Agave gentryi will present more production of nectar and the sugar concentration during the night, also the receptivity of the night belief. Various parameters were set for the floral biology like the antithesis of the nectar production in milligrams and the sugar concentration in Brix degrees and floral visitors. The results proved that the nectar production (1.82 milligrams per flower) and the sugar concentration (11.52 Brix degrees) increases during the night.
