data from: Wing loading regulates descent time in Liriodendron × sino-americanum samaras: bilateral symmetry and allometric scaling

This dataset contains experimental measurements of descent time for objects of different masses. These measurements provide fundamental kinetic parameters for investigating the biomechanical regulation of wind dispersal in Liriodendron × sino-americanum samaras. This study innovatively integrates trait interactions such as samara size, symmetry, and wing loading to resolve a key trade-off between dispersal distance and seedling establishment. The data offer empirical and quantitative support for understanding the evolutionary optimization of samara dispersal in variable environments.
