6 results about "Vase life" patented technology

The invention provides an ethylene biosynthesis RhACO4 gene for regulating and controlling the aging of Chinese rose flowers and application of the ethylene biosynthesis RhACO4 gene, and belongs to the technical field of gene engineering. The coding nucleotide sequence of the RhACO4 gene is as shown in SEQ ID NO. 1. According to the invention, the fact that two genotypes (ProRhACO4A and ProRhACO4B) exist in an RhACO4 promoter region in 358 tetraploid Chinese rose populations is found for the first time, and the difference is that whether a section of GA dinucleotide tandem repeat sequence (GA-peak) which is 11 times is contained or not. The ProRhACO4A type carrying GA-peak is significantly related to a lower gene expression level, a lower endogenous ethylene synthesis amount and a longer vase life. The invention provides a key gene target, a molecular marker and a technical path for cultivating a new variety of rosa chinensis with a long flowering period through molecular marker-assisted selection or genetic engineering means.

This invention discloses a nano-bandage for preserving cut flowers, belonging to the field of horticultural technology. The nano-bandage consists of a polymer carrier and a bactericide encapsulated therein. The polymer is a mixture of PEG and PDMAEMA. By adjusting the mass fraction and total concentration of PDMAEMA, the particle size of the nanoparticles can be controlled, and their surface can be positively charged. It is prepared using microfluidic co-assembly technology, where the drug-containing organic phase and aqueous phase are instantaneously mixed and purified by dialysis. This nano-bandage actively targets and persistently accumulates on the negatively charged cut surface of fresh cut flowers using electrostatic interactions, forming a physical barrier. It also synergistically inhibits microbial infection through slow-release bactericide and charge adsorption, while its nano-size does not affect vascular function. This invention achieves precise and long-lasting protection for cut flower wounds, significantly extending vase life with extremely low dosage, and has the advantages of high efficiency, safety, and intelligent adjustability.

The application discloses a preservative solution for prolonging the life of cut flowers of Impatiens walleriana and a preparation method thereof, and relates to the field of postharvest preservation technology of Impatiens walleriana. The preservative solution is composed of glucose, gibberellin, 8-hydroxyquinoline sulfate, citric acid and deionized water in a specific proportion, wherein the glucose is 3.0% (w / v), the gibberellin is 25 mg / L, the 8-hydroxyquinoline sulfate is 100 mg / L, the citric acid is 80 mg / L, and the balance is deionized water. When the preservative solution is prepared, the gibberellin is first dissolved in anhydrous ethanol to prepare an alcohol-soluble mother liquor, the 8-hydroxyquinoline sulfate is dissolved in deionized water to prepare an aqueous mother liquor, and then the glucose and the citric acid solution are mixed step by step and constant volume is performed, so that a uniform transparent preservative solution is finally prepared. According to the scheme, the cell membrane integrity of the cut flowers of Impatiens walleriana can be effectively maintained, petal browning and water loss can be delayed, the best viewing period and the vase life of the cut flowers can be significantly prolonged, the commodity value can be improved, raw materials are conventional, the process is simple, and the scheme is suitable for large-scale application.

The invention provides a fresh-cut fresh-keeping agent for fresh rose flowers as well as a preparation method and application of the fresh-cut fresh-keeping agent, and belongs to the technical field of fresh flower preservation. The fresh-cut fresh-keeping agent comprises glucose, a compound antioxidant, a pipeline ion dredging agent, salicylic acid, citric acid, a bacteriostatic agent, a penetrating agent, a defoaming agent and water.

The fresh rose flower fresh-cutting preservative provided by the invention can effectively prolong the vase life of fresh rose flower fresh-cutting, improve the water absorption capacity and inhibit flower falling, all the components are easily dissolved in water and can be dissolved without special operation, and the fresh rose flower fresh-cutting preservative is simple and convenient to operate and beneficial to large-scale production.

The invention discloses a curcuma zedoary cooking-slicing-drying-fresh-keeping integrated production method, and belongs to the technical field of curcuma zedoary processing. The curcuma zedoary processing method comprises the following steps: harvesting curcuma zedoary rhizomes meeting the standard from November to December, performing impurity removal and cleaning pretreatment, cooking the curcuma zedoary rhizomes at 95-103 DEG C for 15-25 minutes, processing the curcuma zedoary rhizomes into slices, ventilating, shading and airing the slices for 1-3 days, and drying the slices at 55-65 DEG C for 2-4 hours to obtain a dry product; and soaking the curcuma zedoary cut flowers in a specific preservative for 15-20 minutes in an environment with the temperature of 2-5 DEG C and the humidity of 65%-75%, draining, ventilating, packaging and refrigerating. The preservative is prepared by step-by-step dissolution, dispersion and mixing. By optimizing processing parameters and innovating a fresh-keeping system, the water content of the dried curcuma zedoary is smaller than or equal to 12%, the cut flower vase fresh-keeping period is longer than or equal to 15 days, active ingredients such as curcumin are effectively reserved, the product quality and commodity value are improved, operation is easy and convenient, and the method is suitable for large-scale application.
