Method for processing unibract fritillary bulb seeds

Abstract

The invention discloses a method for processing unibract fritillary bulb seeds. The method comprises the following steps of: physiologically and morphologically after-ripening the unibract fritillary bulb seeds in a shorter time by using gibberellin and combining a low-temperature sand storage stratification method; performing polyploid induction processing on the after-ripened unibract fritillary bulb seeds by using solution of colchicine; and culturing a new unibract fritillary bulb polyploidy variety with high active ingredient content. The method has the advantages of short processing time, high active ingredient content, high plant environment adaptability and the like.

Description

technical field [0001] The invention relates to a method for treating Fritillaria fritillata seeds. Background technique [0002] Fritillaria cirrhosa D.Don is a perennial herb that grows at an altitude of 3500m-4500m. The bulbs are rare and authentic medicinal materials produced in Sichuan. Modern studies have shown that Chuan Fritillaria is the most commonly used and most effective cough-relieving and phlegm-resolving medicine. steroidal saponins. Fritillaria is an endangered medicinal plant on the plateau, and its commodities mainly come from wild plant resources. Due to long-term overharvesting and excessive digging, coupled with the deterioration of the ecological environment, the wild plant resources of Fritillaria have declined sharply and are facing depletion. [0003] At present, Fritillary fritillary mainly relies on seeds for sexual reproduction, and it is necessary to complete the sowing of seeds before the permafrost period in autumn every year. Due to the mor...

Problems solved by technology

The patent application number is 20061002086.4 "a method for treating spring sowing seeds of Fritillaria sichuanensis", although it solves the problem of after-ripening of seeds, it enables seeds that cannot be sown in time to germinate in the next spring, and improves the germination rate of seeds , but the processing time of this method is longer, the seeds need to be buried in the previous year, and the seeds should be taken out and sown in the spring of the next year, and the time cost is high. In addition, because the genetic organization of the seeds has not changed, the grown plants adapt to the external environment The capacity of the environment has not been improved, and there is a possibility that some plants may die during growth, which will affect the final output of bulbs
