Abstract
|
|
|
|
Catalase, glycolate oxidase, hydroxypyruvate and NADPH-glyoxylate reductases activities in cell free extracts from leaves of 3 cultivars, Suwon 264, IR 36 and Jin Heung of rice plants were studied at different growing stages. Catalase and glycolate oxidase shows inclining activities toward the maximum vegetative growth whereas declining activities in either the enzymes were noticed during the maturing stage. After the photopeiodic condition exhibit increasing hydroxypyruvate and NADPH-glyoxylate reductases activities with time until maturing stage. No significant differences were found in the enzyme activities, and in analytical data of nitrogen, chlorophyⅡ contents, dry weight and soluble proteins among the 3 cultivars.
