Embodiment 1-1

[0031] Embodiment 1-1, a kind of method for promoting Polygonatum polyflora seed germination, carries out following steps successively:

[0032] 1) Select Polygonatum multiflora seeds with the same color and size, plump grains, and no mildew scars, and wash them under running water under rubbing conditions for 30 minutes.

[0033] 2), the cleaned seeds obtained in step 1) were first soaked in warm water at 40°C for 24 hours, and then soaked in 1% (mass %) KNO at 40°C. 3 Seeds were soaked in the solution for 24 hours, rinsed with running water three times, and then soaked in 300 mg / L ethephon solution for 12 hours (room temperature).

[0034] 3), the seeds obtained after the treatment in step 2) are placed in a petri dish covered with two layers of wet filter paper, and cultured in a constant temperature incubator at 25° C. in the dark, keeping the filter paper moist.

[0035] The results obtained after culturing for 45 days: the germination rate is 57.8%, the germination pote...

Embodiment 2

[0040] Embodiment 2, a kind of method of promoting Polygonatum polyflora seed germination:

[0041] Cancel the link of soaking seeds for 12h in the ethephon solution of 300mg / L in step 2) of embodiment 1-1;

[0042] The rest are equal to Example 1.

[0043] The results obtained after culturing for 45 days: the germination rate is 46.67%, the germination potential is 32.2%, and the leaf hair rate is 3.3%.

[0044] details as follows:

[0045] The 14th day is dew white, the 20th day root length is 1.7cm, the radicle length of some seeds is about 4cm on the 28th day, the cotyledon is seen on the 35th day, and the number of side buds reaches 5 on the 45th day, the root length is 5.8cm, and the fibrous root The maximum number is 5.

Embodiment 3

[0046] Embodiment 3, a kind of method promoting Polygonatum polyflora seed germination:

[0047] Change the ethephon solution of 300mg / L in embodiment 1-1 step 2) into the gibberellic acid (GA 3 ) solution; all the other are equal to embodiment 1.

[0048] The results obtained after culturing for 45 days are shown in Table 1.

Abstract

The invention discloses a method to promote germination of Polygonatum cyrtonema seeds, comprising the sequential steps of washing Polygonatum cyrtonema seeds to remove surface impurities; soaking thewashed seeds in a warm solution, and soaking in a plant hormone, to be specific, soaking the seeds that are soaked in the warm solution, in KNO3 solution having a mass concentration of 0.5-1.5% at 40+/-5 DEG C for 24+/-2 h, flushing with running water, and soaking a hormone liquid for 12+/-1 h; subjecting the soaked seeds to wet dark culture at 25+/-1 DEG C to germinate the seeds. The method canbreak hibernation of Polygonatum cyrtonema seeds, promote the germination of the seeds, shorten the growth age limit of Polygonatum cyrtonema seeds and increase benefit for medicine planters.

Description

technical field [0001] The invention relates to a method for promoting the germination of Polygonatum polyflora seeds. Background technique [0002] Polygonatum cyrtonema Hua. is a perennial herb of the genus Polygonatum cyrtonema in the family Liliaceae. It has medicinal, edible, ornamental and beauty value. Polygonatum is mild in nature and sweet in taste. It is a nourishing top grade. It has the effects of nourishing yin and moistening dryness, nourishing kidney and essence, lowering blood fat, lowering blood sugar, lowering blood pressure, improving human immunity, anti-aging, etc. It is also useful in the development of new drugs and health products. Broad prospects. In view of Polygonatum Polygonatum having the characteristics of "medicine and food from the same source", with the deepening of the concept of health, the market demand has been increasing year by year in recent years. At present, the production mainly relies on wild rhizomes and seeds for reproduction. ...
