Abstract

The respiratory rate was determined by using Warburg' respiratory instrument , and the soluble sugar , protein, conductivity rate and peroxidase activity were determined by using the usual chemical analysis methods . The results were as follows :①The peroxidase activities of roots in the mixed Cunninghamia lanceolata and Sassafras tsumu forest were lower than those in corresponding pure forest .②The protein contents and conductivity rate of the roots of Cunninghamia lanceolata in pure forest were higher than those in mixed forest , while those of the roots of Sassafras tsumu were contrary . ③The soluble sugar content and respiratory rate of the roots in Cunninghamia lanceolata mixed forest were much higher than those in pure forest , but the soluble sugar content of the roots of Sassafras tsumu in mixed forest was lower than that in pure forest .The difference of respiratory rate between Sassafras tsumu in pure forest and that in mixed forest was slight .
