Resumen o descripción

We set out to test whether trichome and stomata variation in epiphytic bromeliads in the field would support the hypothesis that trichomes confer protection from excess light, increase water absorption and protect the stomata. We characterized the intra- and interspecific plasticity in the morphology and density of trichomes and stomata of 14 epiphytic bromeliad species found in six contrasting vegetation types (coastal sand dune scrub, scrub mangrove, petén mangrove, and deciduous, semi-deciduous and semi-evergreen forest) on the Yucatan Peninsula along a precipitation gradient from 500 to 1500 mm (mean annual precipitation). We performed leaf impressions to determine trichome and stomatal density and to characterize morphology. Trichome morphology did not show variation between sites, but was distinctive for the species. Our data supported the existing hypothesis that trichome density and area were higher in the atmospheric species that inhabited the drier sites, compared with the wetter extreme, which may confer higher protection against photoinhibition and desiccation. Stomatal density increased with precipitation intank species, and negatively correlated with vapour pressure deficit during the dry season. Fewer trichomes and greater numbers of stomata than expected by rainfall were found in mangroves that maintained low vapour pressure deficit during the dry season.
