Abstract

The invention discloses a method for improving the germination rate of polygonatum kingianum seeds. The method comprises the following steps: (1) seed treatment: placing polygonatum kingianum fruits in a black plastic bag for fermentation at 22-28 DEG C for 12-18 days; manually scrubbing to remove peels and large pieces of pulp to obtain seeds attached with the pulp; carrying out enzymolysis treatment on the obtained seeds by using cellulase and pectinase; rinsing the seeds with clear water, and gently scrubbing to obtain clean seeds; placing in a room and airing surface moisture; preserving at low temperature of 4 DEG C; (2) seed germination: gauze is adopted as a germination bed, distilled water is used for fully wetting the germination bed, the germination bed is placed in an illumination incubator, and the humidity of a germination dish is 65-75%; the method is low in cost, the germination rate of the polygonatum kingianum seeds is increased, the mildew rate of the seeds is reduced, the loss of the polygonatum kingianum seeds is reduced, and the method can be popularized and applied in production.

Description

technical field [0001] The invention relates to the field of medicinal plant seeds and seedlings, in particular to a method for improving the germination rate of Polygonatum yunnanensis seeds. Background technique [0002] Polygonatum kingianum (Polygonatum kingianum Coll.et Hemsl.) is a perennial herb of the Liliaceae Polygonatum genus. It is one of the native plants of Polygonatum as a medicinal material stipulated in the 2020 edition of the Pharmacopoeia of the People's Republic of China. It is the key development of Yunnan Province. to medicinal herbs. At present, Dianhuangjing is mainly used for seedling, but the germination rate of seeds is low. In addition, the seeds of Polygonatum yunnanensis are difficult to clean, and a small amount of pulp will be attached to the surface of the seeds, which leads to a high rate of mildew of the seeds of Polygonatum yunnanensis during the stratification process. [0003] At present, the main methods for promoting Polygonatum spp ...
