The foliar blade thickness was analyzed in two tetraploid (2n=104) species of Leucaena , L. leuccocephala and L. diversifolia and in hybrids between both, in a total of 25 plants. For each plant, 10 leaflets were measured. The hybrids presented intermediate average values of foliar blade (116.3 - 148.3µm) in comparison with the parental species values (136.1-158.4µm and 169.2- 170.3µm for L. leucocephala and L. diversifolia, respectively) and a smaller invidual variation.
