Changes in α- and β-amylase activities during seed germination of clover (Trifolium repens)

Changes in α- and β-amylase activities in the cotyledons of germinating clover were examined. The activity of α-amylase decreased during germination and growth of seedling, while β-amylase activity increased. These changes are different from those of germinating seeds of many other plants, but similar to the germinating seeds of alfalfa, which belongs to the same tribe (Trifolieae) as clover.
