Abstract

Abstract: Effects of single and combined pollution of Cd and Zn on chlorophyll content and scavenging system of activated oxygen in leaves of Ottelia alismoides (L. )Pers. was measured. The results showed that the activity of SOD, POD and CAT was up to the highest point at 0.1mg稬^-1 of Cd culture concentration and decreased afterwards. The content of chlorophyll decreased with the increase of Cd culture concentration. Amuch more difference appeared when Zn was added to the solution than single Cd stress, which indicated that Zn strengthened the toxic effect of Cd. There was a synergistical action between Cd and Zn on the effect of scavenging system of activated oxygen and chlorophyll content.

Key words: Bursaphelenchus xylophilus, Antennal sensilla, Volatiles of Pinus, Electroantennogram responses
