Abstract:
Commercially available rose saplings have been conventionally grafted a rose scion on a wild rose stock, however shoots grown from a single wild rose rootstock are effectively used to graft many kinds of roses so as to bloom various flowers. The invention provides a method of grafting many kinds of roses on a single wild rose stock to bloom various flowers by paying attention to lateral buds formed on one or several shoots grown from a wild rose rootstock and grafting many kinds of perpetual rose scions on each notched opening with a lateral bud, which makes it possible to enjoy roses planted in a pot even in a small space, and rose saplings thus produced.
Abstract:
A grafting method comprises the steps of, first preparing a stool by right transverse cuts through a limb or trunk, meaning that the limb or trunk of a tree or shrub is cut at essentially right angles. Root and scion stocks are grafted to the stool using the well known bark grafting technique. The stool is then placed into a rooting medium with the grafted root stock immersed in the medium. Appropriate heat and water is made available to ensure that the root stock is established and that sufficient nutrients and moisture is conducted to the scion stock through the stool.
Abstract:
The procedure is based on the use, as vegetable starting material for the transformation, of the first shoots from the graft of buds of adult trees onto stock, the genetic transformation of explants from the adult shoots by mean of co cultivation with Agrobacterium tumefaciens in mother plaques, and the obtaining of complete adult woody plants by means of in vitro micrografting of the transgenic buds, apices or shoots, regenerated by means of the explants, by means of in vitro micrograft onto stock cultivated in vitro.This procedure makes it possible to avoid the juvenile period and the high heterozygosis which affects most woody species, blossoming and fruiting of the transgenic plants are brought forward, and it permits the direct genetic transformation of commercially interesting varieties.It has argicultural applications.
Abstract:
A machine for the surface treatment of long, narrow objects, more particularly vine shoots, with the following features:a frame fixture (3), that defines the direction of motion (32);at least one conveyor module (4), that has at least one pair of conveyor rollers (14), with a conveyance channel between them, and that is arranged with these along the axis of motion (32);at least two brushes (20, 20a) that define a processing channel that runs along the axis of motion (32).
Abstract:
A grafting film is provided which is formed of a film of a polyalkylene polymer having a self-adhesive property and an elastic memory which causes the film when stretched around a scion and rootstock graft union to gradually contract around the graft union and apply an increasing amount of pressure circumferentially around the graft union. The film also has oxygen and CO.sub.2 permeability properties which cause a gas volume isolated by the film adjacent the graft union to have a higher CO.sub.2 concentration and a lower oxygen concentration relative to the ambient environment around the plant. The film preferably has at least 12% oxygen permeability and less than 2% CO.sub.2 retention. The film is preferably less than about 60 .mu.m thick and more preferably less than about 50 .mu.m thick.
Abstract:
Device for Vee-grafting, especially for hard-and-stone-fruit trees, with an angled knife (8) for cutting a groove (K) in the stock (10) arranged to move in an outer part (2), formed as a guide space by means of a toggle lever (31, 32, 33), which is inclined in relation to the axis of the stock, characterized in that there is an inner part (3) moveable inside the outer part (2) in the forward region (3') or front end of which is fitted the knife (8) and in the rear region (3") of which there is an aperture (7) for the scion (12) and where the outer part (2) has an aperture (4) in its forward region (2') for the stock (10) and in its rear region (2") an aperture (5) which can be caused to coincide with the aperture (7) in the inner part (3) and has an angled knife (6) at the forward edge.
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.
Abstract:
The engrafting machine comprises a carrying frame to which is mounted an endless apron conveyor with measuring clamps and a sorting device having sequently disposed calibrating cams. Underneath each cam is formed in the frame a pocket for collecting the sorted grafts and stocks. The measuring clamp is provided with a movable and an unmovable jaw. To the movable jaw is connected a lever with a control pin that is disposed perpendicularly to the plane of the calibrating cams. In the charging zone of the endless apron conveyor are provided feeding cams for opening the measuring clamps. Parallel below the endless conveyor in its charging zone is fastened an auxiliary apron conveyor with pressing elements. Sequentially in the direction of the movement are disposed an one-disk and a two-disk cutting apparatus. To the carrying frame is mounted further an engrafting apparatus.The described machine is used in the preparation of vine planting material in the agriculture.
Abstract:
Disclosed is a pinching clip which comprises a pair of pinching arms interconnected through the medium of a hinge portion, an elastic brace disposed astraddle said hinge portion and joined at the opposed extremities thereof with the rear sides of said pinching arms, and damping pieces disposed one behind each said pinching arm in such a way that when the two pinching arms are closed by virtue of the pressure exerted thereon by the finger tips, the otherwise possible sudden closing motion of the clip will be retarded. When the clip is closed, the damping pieces disposed on the rear sides of the pinching arms produce an action of retarding the movement of finger tips, with the result that otherwise possible sudden closing motion of the clip is retarded when the clip changes form from its opened state into its closed state.
Abstract:
A method of propagating roses by grafting as a veneer onto cuttings of understock in which the understock cuttings have been unrooted, uncallused and de-eyed.
