The invention relates to the technical field of gerbera jamesonii picking and processing, and discloses a gerbera jamesonii post-harvest processing system and method based on different harvest maturity classifications, the system comprises a control module, an information acquisition module, a maturity classification module and a post-harvest processing execution module, and each module is provided with a clear priority; the method comprises the steps of information acquisition, maturity classification, post-acquisition processing, quality detection and transportation, and priority conflict processing. The information acquisition module preferentially acquires environmental data, the classification module classifies low maturity, medium maturity and high maturity based on three-dimensional logic of temperature, variety and market demand, the processing module matches pre-cooling, fresh-keeping and packaging parameters according to the maturity, and the control module processes conflicts and deviations. The method can reduce the quality loss of the picked gerbera jamesonii, improve the treatment efficiency, reduce the cost, meet different market requirements, and is suitable for large-scale treatment of the picked gerbera jamesonii.

The application discloses a method for evaluating the anti-neck-bending capacity of fresh-cut gerbera flowers, and the specific steps of the evaluation method are as follows: step 1, preparing a measuring platform; step 2, marking the barycenter, marking a G point at the barycenter and a T point 4-6 cm below the barycenter; step 3, placing samples, placing the fresh-cut gerbera flowers steadily on the measuring platforms A1 and A2, and detecting the T point at the marked detection position of the flower branch, which is located in the suspended section in the middle of the two platforms; step 4, anti-neck-bending determination, vertically pressing the marked detection position T point of the flower branch by using a plant anti-lodging tester until the flower branch is bent, and recording the maximum pressure value; step 5, repeated determination, and taking the average value as the anti-neck-bending value of the sample flower branch. The method for evaluating the anti-neck-bending capacity of fresh-cut gerbera flowers uses a pure physical means to evaluate the anti-neck-bending capacity, compared with other evaluation methods, simplifies the detection means and process, greatly improves the detection efficiency, and is convenient for use in the quality detection of fresh-cut flower products in commercial circulation.

This invention discloses SSR marker primers specific to the filamentous petals of gerberas and their applications. This invention utilizes SSR molecular markers to effectively identify different filamentous petal traits in gerberas, resulting in an SSR marker primer that can rapidly and accurately identify the petal traits of gerbera plants with different filamentous petals and the F1 generation of interspecific hybrids. The SSR marker primers provided by this invention can effectively distinguish between filamentous and non-filamentous petals in gerberas and exhibit significant polymorphism, with an accuracy greater than 65%. Furthermore, compared with traditional morphological trait observation methods, the identification method provided by this invention has better repeatability, saves time, and has high specificity. It can replace traditional morphological identification methods, effectively improving the molecular-level breeding process of gerberas and reducing the identification cycle of traditional morphological trait observation. It also allows for early screening to obtain gerbera offspring with superior filamentous varieties, which is of great significance for gerbera breeding.

The present invention relates to the fields of biotechnology, phytochemistry and food technology and provides an additive for preserving cells, tissues and / or food, and the use of synthetic peptides for the preparation of said additive. The present invention can be used, among other applications, for extending the shelf life of food and providing higher food safety. In one embodiment, the additive of the present invention provides substantial preservation of fruits by a single application of the additive, providing treatment of plants or food to prevent the appearance of harmful organisms such as bacteria or fungi, for example those associated with the rotting of fruits, including strawberries, Xylella fastidiosa in coffee plants and orange groves. In one embodiment, the additive of the present invention provides substantial preservation of flowers or inflorescences by a single application of the additive, providing an alternative to the rapid wilting, rotting or appearance of fungi associated with the storage, transport and / or pharmaceutical processing of flowers or inflorescences with phytochemical value, including Gerbera, industrial cannabis (Cannabis), among others. In one embodiment, when the additive is applied, in addition to delaying the germination process, the additive of the present invention also provides substantial preservation of the metabolic state of the sprouts or seedlings and can therefore be used to synchronize germination and adjust the time of planting or germination, as well as other agronomic or botanical advantages.

The invention belongs to the technical field of biological prevention and control of plant diseases, and particularly relates to a composite biological prevention and control fungicide for preventing and controlling gray mold of gerbera jamesonii and a preparation method of the composite biological prevention and control fungicide. The microbial agent is prepared from the following components in parts by weight: 15 to 35 parts of bacillus subtilis, 8 to 25 parts of trichoderma harzianum, 10 to 25 parts of bacillus amyloliquefaciens, 3 to 12 parts of lactobacillus plantarum, 2 to 8 parts of chitosan solution, 2 to 5 parts of seaweed extract and 45 to 75 parts of potassium humate and diatomite composite carrier. The preparation method comprises the steps of strain rejuvenation, liquid fermentation, compound adsorption, low-temperature drying, nitrogen-filled packaging and the like. The bacterial agent can effectively inhibit the growth of gray mold original bacteria and induce the defensive enzyme activity of gerbera jamesonii to be improved through the dual effects of multi-bacteria synergistic antagonism and a chitosan-seaweed induced resistance system.
