Abstract: Three months old seedlings of four woody tropical species [Haematoxylum Campechianum L (Wood blood tree), Tabebuia Rosea (Pink flower tree), Cedrela odorata (Red Cedar) and Swietenia Macrophylla (Mahogany) were fumigated during 6 weeks at three different concentrations of ozone (50, 110 and 250 ppb) using charcoal filtered air within an open-top chamber from june to july in 2009. Visible damages were identified, effects on phtosynthetic pigment levels (chlorophyll a, chlorophyll b, total chlorophyll and total charotenoids) and soluble proteins content were determined. All studied species ( Wood blood tree, Pink flower tree, Red Cedar and Mahogany) showed sensitiveness to ozone exposure levels, showing decreases in photosynthetic pigments levels and soluble proteins contents. Mahogany and Wood blood tree were the most sensitive species to tropospheric ozone showing greater visible damages.
