Abstract: | Changes in peroxidases and glycosidases activities in cytoplasmic and ionically wall-bound fraction of developing seed of
Hibiscus esculentum were studied. In both fractions, the activity of peroxiases assayed with ferulic acid and caffeic acid as a hydrogen donors,
showed inverse correlation with the cell enlargement (sink size development phase). Activities of glycosidases, on the other
hand, showed positive correlation with the sink development and sink filling period of the developing seed. The role of both
the enzymes, glycosidases and peoxidase in seed development is discussed. |
