Abstract: | Activities of photosynthetic and photorespiratory enzymes viz.,ribulose bisphosphate carboxylase, phosphoenol pyruvate carboxylaseand glycolate oxidase from jute (Corchorus olitorius L.; cv.JRO 632) leaves were compared with those from maize (C4) andsunflower (C3) leaves. The photosynthetic CO2 fixation products,the release of 14CO2 in light and dark following photosynthesisin 14CO2, chlorophyll a: b ratio, gross leaf photosyntheticrate and dry matter production rate were also studied. The resultsshow that jute is a C3 plant. Key words: Jute, Corchorus olitorius, C3 photosynthesis |
