The influence of transport pollution on morphology and development of ascomata of Sawadaea bicornis (Erysiphaceae) in Lviv city
Abstract
The degree of infection of Acer platanoides L. leaves by Sawadaea bicornis (Wallr.) Homma in conditions of Lviv city has been studied depending on the distance of trees localization from the road. The values of the pathological index, the degree of development of S. bicornis ascomata and their number per unit area of leaf surface on different distance from road are given. The analysis showed that these values are comparatively higher for the trees located on the distance by 50 m from the road versus the trees located on more than 300 m out from the road.
