  • Patent number: 5927003
    Abstract: A medium for enhancing growth and availability of water and nutrients during plant growth, comprising a synthetic resin and a support material, the resin consisting essentially of a substantially-linear, non-gelling, water-soluble polymer capable of forming a water absorbing network with the support material, such that the polymer is dispersed within the material upon exposure to water and retains and transports water and nutrients for seedling growth. Use of such polyacrylamides benefits growth by retaining water, reducing evaporation loss, improving yields and enhancing nutrient uptake.

  • Patent number: 5832661
    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.

  • Patent number: 5723406
    Abstract: A method for control of horticulture diseases and decontamination of plant tissue which includes applying a solution of hydrogen peroxide to plant tissue, said hydrogen peroxide being a solution having a concentration of between 0.05 to 3.00%. In some cases the hydrogen peroxide solution has a concentration of between 0.05 and 1.5%. Some forms of the invention may utilize a hydrogen peroxide solution that further includes an acid selected from the group consisting of acetic acid and phosphoric acid. Various structures are used for applying the hydrogen peroxide solution such as hydraulic spraying, misting, fogging, or injecting the hydrogen peroxide into a commercial cooling system. In other cases the hydrogen peroxide solution is injected into a recirculating subirrigation nutrient system solution to control microbial growth in the irrigation water. In some cases the hydrogen peroxide solution is applied to the plant tissue at a variety of stages in the plant production cycle.

  • Patent number: 5643853
    Abstract: Thiol compounds are employed in conjunction with compounds which modulate self proliferation, both as to plants and mammals. The thiol compounds find effect in enhancing the effectiveness of auxin like compounds, either as herbicides or in enhancing root formation. In addition, thiol compounds act in conjunction with cytotoxic agents in mammals to allow for lower dosages of the cytotoxic agents while retaining the cytotoxic effect against hyperproliferative diseases, such as cancer. The combination finds particular effect against cells dependent upon an isoform of a surface membrane NADH oxidase for proliferation.

  • Patent number: 5642587
    Abstract: A method for accelerating the growth of Taxus X media `Hicksii` and related Taxus species to enhance the production and recovery of taxol and Taxotere from plant tissues is described. The method includes the steps of increasing the production of biomass by cycling growth periods of Taxus plants within a greenhouse or other enclosed structure, harvests of plant parts and cold storage of the remaining unharvested plants to break dormancy and condition the plant for the next cycle of growth and harvest. After at least several cycles, entire plants are harvested for extraction from all plant parts while other plants are saved for stock plants or reforesting. The collected plant material is prepared for extraction of taxol or Taxotere, compounds used in the treatment of cancer.

    Abstract: An improved method of growing an Easter lily or other species of the genus Lilium is disclosed. A bulb scale from a substantially pathogen-free lily plant is propagated in a growing medium to form a bulblet which is thereafter grown in plant form rather than bulb form. The bulblet is planted and the young plant is grown under conditions of short days to prevent flowering and encourage foliage and root formation. After the initial short-day growing period of approximately thirty-four weeks, a three week period of long-day conditions initiates flowering. Subsequently, a three month period of natural lighting effects the final growth and finishing of the desired lily plant.

    Abstract: An improved rose plant propagation process which can be carried out on an expeditious basis is provided. Stem segments from a scion rose plant and an understock rose plant are obtained during an active stage of growth. An end of a scion segment is placed into a cut formed in an understock segment, and an end portion of the understock segment is placed in a rooting medium. Roots simultaneously are formed on the understock segment while a graft union between the scion and understock rose plant stem segments is formed. The portion of the understock stem above the graft union next is removed. The process of the present invention offers a reliable rose plant propagation technique not heretofore available to the rose industry whereby quality new rose plants readily can be formed on an economical basis in a significantly shorter period of time than commonly required for prior rose plant propagation techniques.
