Agmatine iminohydrolase activity during development and germination of groundnut seeds.

During the development of groundnut seeds agmatine iminohydrolase activity increased in the cotyledons but remained constant in the embryo. In seeds stored for 1 year, decreased activity of the enzyme was found in both cotyledons and embryo. During germination, the enzyme activity increased in the cotyledons, but in the embryo it increased up to day 3 and then decreased to the initial level.
