Abstract
Gas-discharge photography was used to study the physiological condition and degree of damage of the foliage of seven species of trees growing near cement factories in the Republic of Georgia. The results showed that the cement dust caused a reduction in leaf size and altered the optical density and physiological parameters of the leaves. Morus alba was more resistant than the other species, viz. Salix babylonica, Robinia pseudoacacia, Juglans regia, Quercus longipes, Elaeagnus angustifolia and Populus canadensis.
