This study was conducted to diagnose the health of street trees with physiological characters, and to figure out the relation of physiological characters and cambial electrical resistances. Ginkgo biloba, Prunes serrulata and Salix koreensis were chosen in the Cheonan City. Soils under trees were collected to analyze dehydrogenase activities, and chlorophyll content, nitrate reductase and superoxide dismutase activities were analyzed from leaves sampled at the edge of crown in July. Cambial electrical resistances were measured in May, July and September, Soils with low dehydrogenase activity reflected the level of pollution. Chlorophyll content was the lowest in the leaves of P. serrulata at the Dongseo-street. Nitrate reductase activity of Ginkgo biloba was higher than P. serruluta and Satix koreensis. Nitrate reductase activity showed higher activity in the city than control(Independence Hall and Yonam College), but superoxide dismutase activity in the city lower than control. P. serruzatu in the Dongseo-street that cambial electrical resistance increase continuously during the growing season, showed the loss of vitality Cambial electrical resistance was negatively or positively correlated with nitrate reductase($r^2$=-0.566) and superoxide dismutase activity($r^2$=0.579). It was concluded that cambial electrical resistance might be suitable for diagnosing the tree health. |
