  • Method for the preparation of hydrated, pregerminated seeds in gel capsules
    Patent number: 4780987
    Abstract: Novel methods are provided for the preparation and delivery of botanic seeds which are pregerminated and maintained in a hydrated state in gel capsules. Various types of botanic seeds are encapsulated, in some embodiments, with beneficial additives, in a gel matrix and pregerminated. These pregerminated seeds emerge more quickly than raw seeds from a number of planting matrices. These seeds can be encapsulated and pregerminated in variously described ways.
