Evaluation Method of Seed Quality of Shandougen

Abstract

The invention discloses a method for evaluating the quality of Subprostrate Sophora seeds. The method comprises the following steps: dividing seed batches, and drawing 1000 g or more of the seeds of every batch as a detection sample; determining the weight of the water content to be 0.185, the weight of the thousand seed weight to be 0.175, the weight of the germination rate to be 0.425 and the weight of the purity to be 0.215 by adopting the water content, the thousand seed weight, the germination rate and the purity as evaluation factors; determining the evaluation index of every evaluation factor: measuring the evaluation index A of the water content, the evaluation index B of the thousand seed weight, the evaluation index C of the germination rate and the evaluation index D of the purity of the seed batches; and calculating the index value according to the following formula: PI = 0.185A + 0.175B +0.425C + 0.215D. The method realizes quantitative evaluation of the quality of the seeds of Subprostrate Sophora seed batches, the selected evaluation factors can effectively reflect the quality of the seeds, and the method also has the advantages of simplicity in operation, reliable result, and overcoming of the blindness and the hysteresis quality of routine determination.

Description

technical field [0001] The invention relates to the technical field of seed quality evaluation. More specifically, the present invention relates to a method for evaluating the quality of bean root seeds. Background technique [0002] Shandougen, also known as Guangdougen and Vietnamese locust tree, is the dried root of the leguminous plant Sophora vietnamese. It has the effects of clearing away heat and detoxifying, reducing swelling and relieving throat. Gum swelling and pain, sore tongue embolism. Shandougen is an important variety of "Gui medicine" and "South medicine". The Chinese patent medicine products that have been successfully developed include Ganyanling injection, Guilin watermelon cream, Nasopharyngeal tablets, Qingyan Yihuo pills, etc. [0003] Due to the large market demand for the medicinal materials of mountain bean root and the shortage of raw materials, the area of ​​artificial cultivation of mountain bean root in Guangxi has been continuously expanding ...

AI Technical Summary

Problems solved by technology

The artificial planting of Shandou root is mainly based on seeds and tissue culture seedlings. Due to the lack of corresponding seed quality evaluation methods, the quality of commercially available seeds is low, and incidents of counterfeit and inferior seeds pitting farmers often occur, resulting in reduced or no harvest of medicinal materials.

[0004] At present, it is mainly to observe the quality of bean root seeds with the naked eye. How to quantitatively describe the quality of bean root seeds according to the moisture content, thousand-grain weight, germination rate, and clarity of the bean root seeds has not been suitable. Methods
