PARTIAL IDENTIFICATION OF DARK 14CO2 FIXATION PRODUCTS IN LEAVES OF CATTLEYA (ORCHIDACEAE)

Abstract

Summary: Following exposure of Cattleya leaves to 14CO2 in the dark, labelled malate, citrate and an unidentified compound were detected by thin layer chromatography. This is interpreted to suggest the existence in Cattleya leaves of a dark CO2 fixation pathway which may be similar to that found in other plants which can fix large amounts of carbon in the dark.
