Effects of Cr6+ on the POD of Leaves of Brasenia schreberi Gmel. Winter Buds

Abstract

Abstract: Effects of Cr⁶⁺on the POD of leaves of Brasenia schreberi Gmel. winter buds were studied. The leaves of winter buds were treated with solutions containing various concent ration of Cr⁶⁺. The results indicated that both the activity and the isoenzyme spectrum of POD changed with treatment of various concentration and time. Af ter the treatment of Cr⁶⁺, there appeared 2 new isoenzyme spectrums of POD. We also found that there is no direct relationship between the appearance of isoenzyme spectrums and the treating concent rations of Cr⁶⁺. At the same time, the total activity of POD first increased to a apex and then declined.

Key words: Cr⁶⁺, brasenia schreberi Gmel., winter buds, leaf, POD, isoenzyme
