Abstract: A delivery unit of plant tissue of the present invention comprises a vessel in which meristematic tissue having the ability to grow into an entire plant body through differentiation is received. The body of the vessel is made of water-soluble substance and the interior thereof is covered with a water-insoluble substance. Hydrogel is charged in the vessel and the meristematic tissue is held by the hydrogel in a state in which its root or rooting portion is embedded therein or it is placed on the hydrogel. The vessel has a structure of a closed type with a cap or an open type. When the delivery unit of plant tissue is seeded in a medium, the water-soluble substance of the vessel body is dissolved by water contained in the medium and the bud and root grown out of the meristematic tissue breaks the thin film made of a water-insoluble substance which is provided in the interior of the vessel so as to further grow out.

Abstract: A method in which a plant meristematic tissues which retain aqueous liquid on their surfaces are mixed with fine powder, thereby forming powder-coated bodies to which fine powder is adhered at the periphery thereof, so that meristematic tissues are separated from each other. A quantity of water or a liquid mainly consisting of water large enough to make fine powder adhere to the surfaces of the meristematic tissues which can grow into entire plant bodies directly or after they have passed through differentiation and organogenesis. The meristematic tissues are mixed with the fine powder which does not indicate adhesiveness at least during the mixing process. This mixing process is effected in such a manner that the powder is adhered to the tissues by gently shaking or agitating them without applying excessive shearing stress to the meristematic tissues.
