摘要：

Ribulose-1,5-bisphosphate (RubP) carboxylase was isolated from bark tissue of Populus tremuloides Michx. by a one-step Sephadex G 100-120 column chromatography procedure. The peak fraction had a specific activity of 1.3 mu mol CO2 mg(-1) chlorophyll min(-1). The bark RubP carboxylase activity was comparable to that of leaf tissues. Thus, young corticular tissues are photosynthetically competent and contain sufficient RubP carboxylase to account for the reported rates of photosynthesis.
