Germination method of descurainia sophia seeds

Abstract

The invention discloses a germination method of descurainia sophia seeds. The germination method comprises the following steps: 1, preparing a 10-20% HO aqueous solution or distilled water; 2, adding into a centrifugal tube; 3, 1-2 g of descurainia sophia seeds are weighed and placed in a centrifugal tube; 4, placing the centrifugal tube on an oscillator, oscillating, and preprocessing for later use; 5, putting the pretreated seeds into a standard sieve, and washing the seeds with tap water once every 10-20 minutes to keep the seeds wet for 4-6 hours; 6, wetting the bed with distilled water, and putting the treated descurainia sophia seeds into a germination box; 7, placing the germination box in an incubator for germination cultivation; by means of the method, the germination rate, the seedling fresh weight, the plant height and the root length of the descurainia sophia seeds are increased, growth of the descurainia sophia seedlings is promoted, and meanwhile the germination temperature range of the descurainia sophia seedlings is remarkably widened compared with the prior art.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a germination method for seeds of Artemisia spp. Background technique [0002] Artemisia spp., cruciferous family S. spp., is an annual or over-annual herb with vigorous vitality, strong cold resistance and salinity resistance. Artemisia somnifera has many effects, and its seed oil content is as high as 39% to 44%. It is a high-quality edible oil and industrial oil, and the content of unsaturated fatty acids such as oleic acid, linoleic acid, and α-linolenic acid is high. [0003] In medicine, the plants and seeds of Artemisia somnifera can also be used as medicine, which has obvious effects on cardiovascular diseases, blood lipid regulation, and cough relief; Artemisia somnifera has also been applied in agriculture and animal husbandry, and can be used as livestock feed. The juice filtered by water beating can be used as a biological pesticide to kill aphids and cabbage insects. ...

AI Technical Summary

Problems solved by technology

[0004] However, people found in the process of planting Artemisia basilica that there were problems such as long dormancy time and low germination rate in the seeds of Artemisia basilica. Soaking in HCl can break the dormancy of Artemisia persicae seeds; Pu Huiming et al. found that mechanical breaking and GA3 treatment can also effectively break the dormancy of Artemisia persicae seeds, and the germination rate increased to 43.97%; however, most of these methods used Chemical reagents that are not easy to decompose or high-concentration reagents have environmental pollution risks and high investment problems, and some operations are cumbersome and have low germination potential, which is difficult to achieve in actual production applications. Seeds can only germinate when the temperature is adjusted to 20-25°C, which has high environmental requirements, which further limits the propagation speed of Artemisia persicae
