Resumo: | This study aimed to evaluate the existence of leaf anatomic characteristics in Tabebuia alba changed by air pollutants, which could be used as tool for a bioindication program. The quantification of mutagenic events on pollen grains also were measured. For this, median leaves and pre-anthesis flowers were collected from the adult plants from three places of Curitiba and one place in Araucaria, all nearby to the air monitoring stations. The comparison of the four study sites showed a reduction in leaf area, an increasing of stomatal density, subepidermic layer, epidermis in both faces and the amount of micronucleus. Also, there was reduction of chlorophyllian parenchymas at the site where there was the higher average for the ozone level. It was concluded that these modifications might be a consequence of the effect of troposferic pollution on T. alba plants. However, further studies with this species would be necessary to confirm its potential for bioindication. |
