Peroxidase, polyphenol oxidase and catalase isoenzymes during germination and early plant development of tall and dwarf wheats (Triticum aestivum L.)

Abstract

Isoenzyme pattern of peroxidase, polyphenol oxidase and catalase at different intervals during germination and in different plant parts during early development of 'C-306' and 'Hira' cultivars, representing tall and dwarf wheats, respectively were investigated. The number of isoenzymic components of the three enzymes increased progressively with the concomitant increase in the stage of germination. The isoenzymic patterns, in general, were more clear and better developed during the later stages of germination. Different tissues or organs of the wheat plant possessed specific isoenzymic pattern of these enzymes. Differences between cultivars were observed both in the number and relative intensity of the various isoenzymic fractions.
