摘要

method of preventing flooding of a cavity within a sprout containment of a manufactured seed, manufactured seed, and, nutrient medium. The invention provides methods of preventing flooding of a cavity within a sprout containment of a manufactured seed by lowering the water potential of the nutrient medium relative to the water potential of a plant embryo disposed within the cavity. An exemplary method comprises the steps of: (a) assembling a manufactured seed comprising a seed coating and a sprout containment, wherein the sprout containment comprises a cavity; (b) lowering the water potential of the nutrient medium to be used in the manufactured seed, the water potential of the nutrient relative to the water potential of a plant embryo disposed in the bud containment cavity is such that an excessive amount water does not flow from the nutrient medium and does not accumulate within the cavity, thereby preventing flooding of the cavity; and (c) adding the nutrient medium prepared in step (b) to the manufactured seed.
