The invention discloses a method for establishing a fenugreek efficient regeneration system, and belongs to the technical field of medicinal plant tissue culture. The establishment method comprises the following steps: (1) inoculating a fenugreek explant into a primary induction culture medium containing 5-azacytidine, spermidine and fluridone, and carrying out induction culture to generate an adventitious bud; (2) dividing the adventitious buds, and then transferring the adventitious buds into a proliferation culture medium containing trehalose, paclobutrazol and uridine for culture to realize amplification of the adventitious buds; and (3) transferring the stem segments obtained by multiplication culture into a rooting culture medium containing sodium nitroprusside and jasmonic acid methyl ester for culture, and inducing rooting. According to the established efficient sterile rapid propagation system for fenugreek, the adventitious bud differentiation rate reaches 91.3%, the propagation coefficient is 10.8, the rooting rate reaches 97.5%, the propagation speed is high, high-quality seedlings can be produced on a large scale, and meanwhile the yield and quality are improved.

The invention discloses an epimedium sagittatum seed embryo after-ripening method. The method comprises the following steps: disinfecting, washing and drying herba epimedii seeds; spraying fluridone onto the river sand, and treating for 24 hours; then putting the river sand into a roller, then putting the epimedium seeds into the roller, and carrying out rolling priming treatment for 24 hours; then gibberellin is used for treatment; the humidity state of the seeds in the roller is observed, and if the seeds are dry, the seeds and the river sand are poured out and treated with gibberellin with the same concentration; the seeds are longitudinally cut at regular intervals, the embryo completion condition is observed until white buds appear, namely endosperm grows out of germs, and embryo after-ripening is completed. According to the method, on the basis of a roller initiation technology, solid media, hormones and medicament treatment are combined, so that epimedium seed embryos are subjected to initiation dynamic treatment continuously in the embryo after-ripening process. According to the method, seed rotting can be overcome, the integrity of cell membranes of the seeds is guaranteed, and the albino seedling phenomenon caused by damage of the cell membranes is avoided. The seed utilization efficiency and the time efficiency are improved, and a foundation is laid for improving the seedling raising efficiency of the herba epimedii.
