Chlorophyll differences in chlorotic Cinnamomum camphora leaves

    Corresponding author: ZHANG De-shun

Abstract: In the middle and lower reaches of the Yangtze River region in recent decades,chlorotic Cinnamomum camphora has become more and more serious with urban landscape and greening benefits degraded due to physiological disease of this tree species. In this research,physiological and biochemical properties of chlorotic C. camphora leaves from trees in typical planted areas of Shanghai (botanical gardens,leisure open spaces,and sides of highways) and chlorophyll variation were studied. Results of chlorophyll (Chl) differences in chlorotic C. camphora leaves showed decreases in Chla(91.2%),Chlb(95.1%),carotenoids (82.2%),the ratio of chlorophyll/carotenoid(58.5%),superoxide dismutase(SOD)(46.4%),and peroxidase(POD)(66.6%),compared to the health leaves. Also,the active iron content in yellow leaves was 50%-65% of health leaves,and the chlorophyll a/b ratio of the serious yellow leaves increased 98.7%,compared to the health leaves. The relative increase in carotenoid content could result in chlorotic C. camphora,whereas POD and SOD activity could indicate the degree of chlorosis.[Ch,8 fig. 2 tab. 20 ref.]
