The study aims to quantify dew absorption in plants and analyze how leaf microstructures affect this process across different species.
Conducted a stable isotope tracer experiment to measure dew absorption rates under varying dew amounts.
Analyzed leaf surface morphology and microstructures of various plant species during dew formation.
Compared absorption rates among four different plant species to assess their dew absorption capabilities.
Tillandsia ionantha showed a high dew absorption rate of 92% at a dew intensity of 0.1 mm due to its specialized leaf trichomes.
In contrast, Oxalis triangularis exhibited a low absorption rate of only 1.43% due to hydrophobic leaf surface.
Dew absorption varied significantly among species under different intensities, with T. ionantha consistently outperforming others in absorption rates.
Epipremnum aureum demonstrated the ability to transport absorbed dew to its roots, indicating an internal redistribution mechanism.
