Abstract:
A method and apparatus for a Phytoimmune system to manage diseases in fruit trees, in which concomitant in vitro micrografting is used with actively growing plant tissue to create Complex Architecture Plants capable of generating immune, resistance, or tolerance responses to specific targeted plant diseases, such as the bacterial disease Huanglongbing (HLB), also, known as Citrus Greening Disease, and the viral disease Plum Pox Virus (PPV), also known as Sharka disease.
Abstract:
A tree harvester includes a body and a harvesting system coupled to the body. The tree harvester further includes a control system coupled to the body. The control system is configured to receive data from the harvesting system regarding a characteristic of a harvested tree and control operation of the harvesting system based on the data. The harvesting system is configured to remove an intermediate portion of the harvested tree below a tree crown and graft the tree crown to a tree stump.
Abstract:
Provided is a novel plant body comprising a plant tissue of a plant belonging to the family Solanaceae, Brassicaceae, Lamiaceae, or Orobanchaceae, wherein graft incompatibility is avoided or suppressed by using a graft medium between different-family plants.
Abstract:
A plant graft production line for automatically grafting a rootstock and a scion is disclosed. The plant graft production line comprises (a) a closed-loop conveyor; (b) at least one grafting assembly arranged for transporting along said conveyor; a stationary cutting mechanism for cutting exposed rootstock surface; (c) a stationary cutting mechanism for cutting exposed scion surface; (d) a stationary clipping mechanism for clipping superimposed rootstock and scion together. The rootstock holder is arranged as an at least three point grip. The holder comprises a supporting member having a rounded top arranged to support the rootstock and clamping elements.
Abstract:
The invention relates to the field of watermelon grafting. In particular, double grafted watermelon seedlings and plants are provided and methods for producing such double grafted seedlings and plants.
Abstract:
The present invention relates to a method for the production of somatic embryos from poinsettia (Euphorbia pulcherrima) plant tissue. Furthermore, the present invention discloses subject matter that relates to poinsettia plants, particularly to non-chimeric poinsettia plants, and to a method of producing the same.
Abstract:
Disclosed herein are viral vectors suitable for transfection into woody trees for purposes of delivering and expressing beneficial genes with increased stability. Specifically exemplified herein are vectors for transfecting citrus trees. The vectors allow for the expression of useful proteins, such as those that can protect the tree from disease.
Abstract:
Grafting a scion on a stock is effected by opening a chuck and inserting bar-like members in a storage chamber successively into the chuck with the front end of such bar-like members protruding out of a front end hole 5D, 105D, closing the chuck 4, 104 to thereby hold the bar-like member 2, inserting the front end of the protruding bar-like member 2 into a graft joint end of the stock, separating the grafting device from the bar-like member, and inserting the other end of the bar-like member into a graft joint end of the scion so as to abut the graft joint ends of the stock and scion against each other. The bar-like member can be simply and rapidly inserted into the stock, so that abutment between the stock and scion can be effected with extreme ease.
Abstract:
Starting from a herbaceous cutting, which may be derived from in vitro culture, of stock and of a herbaceous scion, the process consists of inserting the scion (12') having a single bud, into the stock cutting (12), by bevelling the lower end 15 of the scion 12' from two sides 17, 18, by slitting the upper end of the stock cutting in its middle, and by subsequently assembling the two parts 12, 12' by joining 20, of transferring the base of the abovementioned grafted unit into a development medium 21, of moistening the development medium 21 with a nutrient solution and of subsequently placing this unit in a container with a water-saturated atmosphere and at a temperature above 20.degree. C., while suppressing the bud 22 of the stock and growing the saplings in the greenhouse or under a polyethylene tunnel until the desired stage of growth.
Abstract:
A hand-held tool for making grafting-flap cuts in the bark of a tree limb includes an elongated tubular body having an open end for accommodating coaxial insertion of the limb. The end of the body adjacent the open end has a plurality of elongated slots longitudinally disposed in the tubular body. A plug within the tubular body limits the insertion depth of the limb to a preselected distance. A plurality of elongated knife members are provided. The longitudinal axis of each of the knife members registers with the longitudinal axis of one of the circumferentially spaced slots in said tubular body. The knife members are supported by a support ring radially projecting above the outer surface of the tubular body and are disposed in a corresponding plurality of radially projecting circumferentially equally-spaced slots in the support ring. An elastic band is coaxially disposed about the tubular body and engages the other ends of the knife members for biasing the other ends radially inwardly towards the tubular body. The handle end of the body is externally threaded and a collar nut, internally threaded, is adapted for threadably mating with the handle end. The nut has a shoulder angle selected for engaging a cam surface on the other ends of the knife members for applying an outward force thereto for camming the other ends of the knife members upwardly to pivot the knife edges downwardly through the registering slots into piercing contact with the limb.
