Abstract
Methods and materials are provided for coating hydrogel capsules which contain encapsulated meristematic tissue substantially free of intact seed coat with a membrane which controls the migration of solvents and their included solutes between the capsule and its environment, thereby creating an analog to natural botanic seed having an artificial seed coat which provides the benefits of natural seed coat. The membranes may be formed of a single compound or various compounds which provide control over the migration of distinct elements.
