Greene, D.F., Johnson, E.A. (1992) Can the variation in samara mass and terminal velocity on an individual plant affect the distribution of dispersal distances? American Naturalist, 139(4):825-838.

Résumé

For species with winged seeds, coefficients of variation of terminal velocity were usually on the order of 0.13. These values were too low to have a significant effect on distance variation because of the much larger magnitude of the turbulent intensities of the wind in the vertical and horizontal directions. There is unlikely to be selection for mass variation to reduce sibling densities and therefore intersib competition. -from Authors
