Abstract: There is a little information on the effect of calcium cloride (CaCl 2 ) which is used as deicing salt in Korea on the physiological responses of the street trees. Prunus sargentii is one of the most widespread tree species of street vegetation in Korea. In this study, the effect of CaCl 2 on photosynthetic apparatus such as chlorophyll fluorescence image and light response curve of P. sargentii in relation to their leaf and root collar growth responses were investigated. To study the effect of CaCl 2 treatment in the early spring, we irrigated twice in rhizosphere of P. sargentii (3-year-old) planted plastic pots with solution of 0.5%, 1.0%, 3.0% CaCl 2 concentration before leaf expansion. Results after treatments, total chlorophyll contents and the chlorophyll a/b, photosynthetic rate, quantum yield, dark respiration decreased with increasing CaCl 2 concentration. On the contrary, light compensation point increased with increasing CaCl 2 concentration. Through the linear regressions of correlation of photosynthetic rate with photosynthetic parameters (quantum yield, dark respiration and light compensation point), we found a significant relationship (p<0.05) between photosynthetic rate and quantum yield and light compensation point except dark respiration. Calcium cloride (CaCl 2 ) induced inhibition of photochemical efficiency (F V ) and non-photochemical quenching (NPQ) were found in treatments of CaCl 2, and these reduction rates between control and CaCl 2 treatments were drastically showed at 80 days. We suggest that physiological activities are limited from treatment of CaCl 2. These reductions of photosynthetic apparatus ability caused eventually the reduction of leaf and diameter at root collar growth.
