Osmophore patterns in Ipomoea asarifolia (Desr.) Roem. & Schult. (Convolvulaceae)

Abstract

To achieve reproductive fitness, floral attractants are essential for insect-plant interaction. Many entomophilous pollination plants have odorous zones, composed of glands that release volatile odors, these odors act as attractants for potential pollinators. Ipomea Asalifoila flowers were used for this study. One of its main characteristics is its infundibuliform morphology and glabrous leaves, and its reproductive structures are located in the center of the flower. In order to better understand the dynamics of the release of these odors, Ipomea A. flowers were collected to perform the test in neutral red 60%, and photographed before, during and after the procedure. These flowers were enveloped and separated by day of anthesis, from the first to the third day, where floral death occurred. After the tests, variations in the days of anthesis of the flowers were observed, with a gradual effect. Besides an osmotic concentration in their reproductive organs.
