Soil dust effects on morphological, physiological and biochemical responses of four tree species of semiarid regions

Dust pollution is expected to be a significant pollution in the urban forests, especially in semiarid environments. The purpose of this study was to evaluate the effects of soil dust on the morphological, physiological and biochemical traits of seedlings of Fraxinus rotundifolia Mill., Morus alba L., Celtis caucasica Willd. and Melia azedarach L. These species are widely grown in Iran’s urban areas, particularly in semiarid regions. The...
