Abstract
The influence of anaerobiosis for 0.5 to 15 hours on the last steps of chlorophyll biosynthesis of etiolated oat seedlings was investigated. Phototransformation of protochlorophyllide to chlorophyllide is only slightly reduced and esterification of chlorophyllide is slightly increased by pretreatment under anaerobic conditions. Pretreated plants accumulate the geranylgeraniol ester of chlorophyllide rather than the phytol ester. Enzymic hydrogenation of the esterifying alcohol geranylgeraniol to phytol is presumably inhibited by anaerobiosis.
