Comparative study on the lipoxygenase activities of some soybean cultivars

The lipoxygenase levels of 10 soybean cultivars (McCall, Tresor, Recor, Essor, F054, Isz15, Chandor, Primor, Gadir, and Eszter) cultivated in Hungary in three consecutive years (1991, 1992, and 1993) were compared with regard to the activities and activity ratios of lipoxygenase isoenzymes. Surprisingly, both the activities and the activity ratios of the given cultivars were different in the three years studied. The differences in activity between the generations of a cultivar were found to be much larger than the differences between the different cultivars from the same year. It is suggested that the weather conditions play a considerable role in influencing the activities of the lipoxygenase isoenzymes in soybean cultivars
