Abstract
A comparative study on the electrophoretic peroxidase patterns of rye (Secale cereale L.), tetraploid wheat (Triticum turgidum L. durum), hexaploid wheat (Triticum aestivum L.), and hexaploid Triticale during kernel germination has been carried out. Endosperm, embryo, coleoptile, and the first leaf have been analyzed. A drastic change in peroxidase patterns was observed during the first hours of germination in all the materials studied. The triticale peroxidase patterns were similar to tetraploid wheat female parent patterns. The chromosomal locations of two leaf peroxidase isozymes of hexaploid wheat 'Chinese Spring' are also reported. These two isozymes, C9 and C10, are associated with chromosome arms 3DS and 7DS, respectively.
