Abstract

Chloroplasts were isolated from the bark of Populus tremuloides Michx. The isolated organelles were able to reduce 2, 6-dichlorophenolindophenol at a rate similar to other plant systems. The total photosynthetic reducing activity of the bark of two trees was found to be 3.8 and 12.1 percent of that of their leaves.
