| Summary: | In low-light environments, plants face challenges in maximizing light acquisition for growth and reproduction. This study investigates the light-related adaptations of <i>Ipomoea purpurea</i> (L.) Roth, a climbing annual vine commonly known as morning glory. Field and laboratory analyses focused on the functionality of its leaf and petal interfaces. We observed that tendrils of <i>I. purpurea</i> enable it to climb surrounding structures, optimizing light capture. The leaves display absorption peaks at 400 nm and 700 nm, typical for plants that absorb light in the red and blue regions, with microstructural features like protrusions and folds aiding in self-cleaning. Petals, exhibiting grid-like patterns and specific reflectance spectra, attract pollinators such as bees. These functional traits, including self-cleaning mechanisms and specialized light absorption, highlight <i>I. purpurea</i>’s unique strategies for thriving in low-light conditions. The findings offer valuable insights into the potential use of <i>I. purpurea</i> for urban landscaping, vertical greening, and ornamental plant selection. |
