Embodiment Construction

[0011] A simplified method for rapid post-ripening of Sessile Acanthopanax seeds:

[0012] 1 Materials and methods

[0013] 1.1 Experimental materials and processing

[0014] In autumn (early October), the mature fruits (black) of Sessile Acanthopanax Acanthopanax were collected, and the mature seeds were quickly washed out with water, and then directly treated with gibberellin (GA 3 ) (concentration controlled at 2.50-3.50 mg·L -1 ) and 2,4-dichlorophenoxyacetic acid (2,4-D) (concentration controlled at 2.20-3.20 mg·L -1 ) solution for 60 h, then mix the seeds with river sand (1:4) and put them into wooden tanks, cover with plastic film and place them indoors for variable temperature treatment, keeping the relative humidity at about 70%.

[0015] 1.2 Post-ripening and sowing of Acanthopanax sessilis seeds

[0016] After the seeds were soaked and boxed by the method in 1.1, the variable temperature treatment was started. The variable temperature treatment was divided into ...

Abstract

The invention relates to a seed propagation technology, and particularly relates to a simple fast after-ripening method of acanthopanax sessiliflorus seeds. The method comprises the steps of soaking the seeds with GA3 and 2,4-D mixed solution and then fishing out; uniformly mixing the seeds and river sand, and then putting the mixture into a wood trough; and performing poikilothermic treatment indoors, wherein in the first stage, the poikilothermic amplitude is 24+/-2 DEG C at daytime and the treatment time is 12 hours, the poikilothermic amplitude is 15+/-2 DEG C at night and the treatment time is 12 hours, and the treatment of the first stage lasts for 80-95 days; and in the second stage, the poikilothermic amplitude is 20+/-2 DEG C at daytime and the treatment time is 8 hours, the poikilothermic amplitude is 5+/-2 DEG C at night and the treatment time is 16 hours, and the treatment of the second stage lasts for 70-75 days. The occurrence rate of cotyledon embryo of embryo can exceed 98.9% in average. The seeds after poikilothermic treatment can directly germinate without a freezing layer, and the germination rate exceeds 97.5%. The method provided by the invention has the advantages of short acanthopanax sessiliflorus treatment time, strong operability, extremely high germination rate and the like, and can be popularized and applied to industrial seedling production and large-scale cultivation of acanthopanax sessiliflorus.

Description

[0001] [0002] technical field [0003] The invention relates to a seed propagation technology, that is, a simplified method for rapid post-ripening of sessile Acanthopanax acanthus seeds. Background technique [0004] Sessile five plus ( Acanthopanax sessiliforus Rupr. Et Maxim. seem), Araliaceae Acanthopanax is a perennial deciduous shrub. It has the functions of dispelling rheumatism, nourishing liver and kidney, strengthening muscles and bones, and activating blood vessels. Traumatic injuries, fractures, edema and beriberi embolism. Sessilis Acanthopanax is very rare in Changbai Mountains. It is a rare and endangered medicinal plant in Changbai Mountains. It is listed as a endangered species in the "List of Rare and Endangered Plants in China (Volume 1)" and is a national second-class key protected plant. It is listed as Endangered Species (NE) by the "Red List of Species in China". In the article "Interim Regulations on the Protection and Management of Wild Animals...
