The Effect of Height, Wing Length, and Wing Symmetry on Tabebuia rosea Seed Dispersal

Abstract

The relationship between the vertical drop height and the horizontal distance travelled (dispersal ratio) was investigated for a sample of fifty Tabebuia rosea seeds by dropping the seeds from five heights ranging from 1.00 to 2.00 meters. The dispersal ratio was found to be a constant 0.16m/m for these heights. The effects of total seed length and asymmetry of seed wings on dispersal ratio were also measured using separate samples of fifty Tabebuia rosea seeds. It was found that neither seed length nor asymmetry had a significant effect on the dispersal ratio
