34 results about "Integument" patented technology

In biology, integument is the natural covering of an organism or an organ, such as its skin, husk, shell, or rind. It derives from integumentum, which is Latin for "a covering". In a transferred or figurative sense, it could mean a cloak or a disguise. In English "integument" is a fairly modern word, its origin having been traced back to the early seventeenth century. It can mean a material or layer with which anything is enclosed, clothed, or covered in the sense of "clad" or "coated", as with a skin or husk.

Water polymer integument and method for preparing integument controlled-release fertilizer thereof

The invention discloses a water-based polymer coated film and a preparation method of a film-coated controlled release fertilizer thereof, which belongs to the agricultural controlled release fertilizer preparation technical field and relates to using a novel water-emulsion type polymer. The polymer film-coated controlled release fertilizer is coating a layer of novel degradable latex polymer film layer on the surface of granular fertilizer. The granular fertilizer with the diameter of 2 to 5mm is packed inside a film coating device of a rotating drum or a fluidized bed, and the granular fertilizer flows inside the film coating device to be heated to 80 DEG C to 100 DEG C. Organic matter is sprayed on the surface of the granular fertilizer, then complex polymer latex is sprayed on the facial surface of the organic matter film layer of the granular fertilizer to be dried continuously, the water of the film layer is removed by complete drying, and the polymer latex film-coated controlled release fertilizer is obtained. The invention conquers the problem that organic solvent leaks to cause the environmental pollution during the process of the production and avoids the problems of solvent recycling; the manufacturing process is easy for realizing the large scale chemical industry production; the investment cost is low; the production cost is reduced greatly.

Method for establishing rubber tree internal integument regeneration system

The invention relates to a method for taking rubber tree inner integument as an explant, in particular to a method for establishing a rubber tree inner integument regeneration system. The method comprises the following main steps: the selection and treatment of young fruits, the selection and treatment of the explant, the induction and subculture of calli, the differentiation of body cell embryoids, and the plant regeneration. The method for establishing the rubber tree inner integument regeneration system has the advantages of simple technological process and low production cost. The inner integument is used to obtain a young scion root clone, thereby overcoming the defects of difficult stamen stripping and serious pollution in a powdery mildew prevalence season lying in the anther culture, and enlarging the source of the explant. The method is characterized by easily obtaining the explant and having the robust regenerated plant. The method provides the good regeneration system for the generalization of the young scion root clone and the seed selection of rootstock, provides a good receptor for genetic transformation, and also provides a new source for the embryo calli with long-time subculture. Therefore, the method has wide application prospect.

Efficient genetic transformation method for embryogenic callus of cotyledon embryo of rubber tree

InactiveCN101775408AHigh embryonic rateStrong tolerance to transforming factorsHorticulture methodsPlant tissue cultureTransformation efficiencyEmbryo
The invention belongs to the field of biotech, and relates to an efficient genetic transformation method for embryogenic callus of cotyledon embryo of rubber tree. The method comprises the following steps: conducting the tissue culture of the anther or the internal integument of rubber trees, using the cotyledon embryo as explant and carrying out induction and genetic transformation; then, inducing the transformed embryogenic callus into embryo and inducing the selected mature embryos into sprouts. The invention provides a simple-flow, extra-high efficiency, low-cost transformation method which overcomes the serious defects like low frequency of embryo production rate in rubber tree genetic transformation system and the long induction time of the embryogenic callus. Meanwhile, the invention also compensates the defect that the obtainment of transformed rubber tree acceptor materials is prone to natural conditions limitations and greatly shortens the transformation circle, thus making it a high-efficient genetic transformation method for rubber free. The invention is of great scientific as well as using value, and also provides a new technical route for the formation of transformation systems for rubber tree.

Highly effective genetic conversion method for gum tree embryonic callus

InactiveCN101186927ASolve the problem of low induction rateImprove the efficiency of forming mature embryosVector-based foreign material introductionTransformation efficiencyEmbryo
The invention discloses a highly-efficient genetic transformation method of the embryogenic callus of rubber trees, which is characterized in that anters of rubber trees or inner integuments which are used as explant are proceeded tissue culture, the culture is induced to produce embryogenic callus of rubber trees, then the embryogenic callus is proceeded successive transfer enrichment culture, and the embryogenic callus after enrichment is utilized as acceptor material to proceed genetic transformation. The successive transfer enrichment culture is proceeded to resistant embryogenic calli which is achieved after the transformation, and the resistant embryogenic calli after the successive transfer enrichment culture is induced the culture to produce embryo which further becomes plants in the process of embryoid induction. The invention has the advantages of simple art procedure, excessively high transformation efficiency and low cost, overcomes the serious shortcomings of extremely low percentage of immature embryos of the existing genetic transformation system of rubber trees, and the like, resolves the disadvantages that the achievement of the materials of transformation acceptor of rubber trees is easy to be restricted by natural conditions, such as seasons, and greatly reduces the transformation period, thereby the invention is an effective genetic transformation method of rubber trees and has great scientific value and application value.
