Metabolic Consequences of Seed Maturation Drying
Development of the castor bean (Ricinus communis L.) seed takes about 60 days to be completed. During that time the embryo and endosperm are initially produced by cell divisions; the cells of the endosperm then expand as the major storage reserves (lipids and proteins) are deposited within them. The termination of development is marked by a period of maturation drying, which commences about the 50th day after pollination (DAP), when reserve deposition is essentially completed. I am interested in determining the events and promoting those essential for germination.
