 Leaf traits can indicate a plants′ function and response to the environment. Leaf functional traits are affected by both genes and the environment. We examined these effects on leaf traits in a Tobacco variety (Tabacum ‘K326’) planted at 11 different sites, and also on 12 different tobacco cultivars grown at one site. Our results showed that genetic variation had a larger impact on stomatal density and leaf thickness than stomatal length and vein density, while the environment had a greater effect on minor vein density and leaf thickness than stomatal length and stomatal density. At one site where temperature was high, Tabacum‘K326’ exhibited its highest minor leaf vein density.
