preparation example Construction

[0031] Polygonatum multiflora seeds used for first soaking in the present invention are preferably Polygonatum multiflora seeds with exocarp removed. In the present invention, the preparation method of the Polygonatum multiflora seed that described exocarp is removed, preferably comprises the following steps:

[0032] The mature Polygonatum multiflora seeds are sealed and placed in a plastic bag for 10-16 days, the pericarp of the sealed Polygonatum multiflora seeds is softened, and the pericarp is rubbed off to obtain the Polygonatum multiflora seeds with the pericarp removed.

[0033] In the present invention, the mature Polygonatum multiflora seeds are preferably mature Polygonatum multiflora seeds collected from September to November every year. In the present invention, the sealing time of the plastic bag is preferably 14d. In the present invention, the steps of washing and drying are preferably further included after rubbing off the peel. The invention adopts the Polyg...

Embodiment 1

[0048] A kind of pretreatment method that promotes Polygonatum multiflora seed seedling, comprises the following steps:

[0049] Take the mature Polygonatum seeds collected from September to November, put them in a plastic bag and seal them for 2 weeks, the seed coat can be softened, rub the peel off, wash it, put the seeds in a cool place to dry naturally, and get the multi-flowered Polygonatum seeds.

[0050] To prepare growth hormone solution:

[0051] Weigh 150 mg of gibberellin, dissolve it with a small amount of 95% alcohol, and then dilute to 500 mL with distilled water to obtain a gibberellin solution with a concentration of 300 mg / L;

[0052] Weigh 100mg of 6-BA, dissolve it with a small amount of 1mol / L NaOH solution, heat it with hot water, and then distill it to 500mL to obtain a 6-BA solution with a concentration of 200mg / L;

[0053] The gibberellin solution and the 6-BA solution were mixed according to the volume ratio of 1:1, the final concentration of gibbere...

Abstract

The invention provides a pretreatment method for promoting seedling formation of polygonatum cyrtonema seeds, and relates to the technical field of plant breeding. The pretreatment method comprises the following steps: soaking the polygonatum cyrtonema seeds for the first time by using a growth hormone solution, wherein the components of the growth hormone solution include gibberellin and 6-BA; storing the polygonatum cyrtonema seeds soaked for the first time in sand for 60-120 days at 2-4 DEG C; soaking the polygonatum cyrtonema seeds after sand storage for the second time by using a gibberellin solution with the temperature of 35-40 DEG C to obtain the pretreated polygonatum cyrtonema seeds. According to the pretreatment method, the polygonatum cyrtonema seeds are soaked by using both the gibberellin and the 6-BA, are stored in the sand at low temperature, and are soaked by using the gibberellin solution with the temperature of 35-40 DEG C to break through dormancy of the polygonatumcyrtonema seeds and secondary dormancy of germs, so that the seedling forming period of the polygonatum cyrtonema seeds takes only 2-3 months and is shortened by 10 months or more, seedlings can be emerged in the sowing year, the emergence rate can reach 40-60%, and the germination rate reaches 85-95%.

Description

technical field [0001] The invention relates to the technical field of plant breeding, in particular to a pretreatment method for promoting seedling formation of Polygonatum multiflora seeds. Background technique [0002] Polygonatum cyrtonema (scientific name: Polygonatum cyrtonema Hua) is a perennial herb of the genus Polygonatum cyrtonema in the family Liliaceae. Oblong-lanceolate, umbel, perianth yellow-green, black berries, flowering from May to June, fruiting from August to October. The rhizome of Polygonatum multiflora can be used as medicine or as an ornamental plant. [0003] Polygonatum multiflora is a species of Polygonatum specified in the "Chinese Pharmacopoeia (2015)", which has the effects of invigorating qi and nourishing yin, strengthening the spleen, moistening the lungs, and nourishing the kidneys. In recent years, with the in-depth research on the efficacy of Polygonatum multiflora and the advent of health care products and medicines for Polygonatum mul...
