Rubus-chingii seed breeding method

Abstract

The invention belongs to the breeding technology, and particularly relates to a rubus-chingii seed breeding method. The rubus-chingii seed breeding method includes the following steps that seeds are pretreated and subjected to acid etching, potassium permanganate treatment, gibberellin treatment and low-temperature stratification, then sowing, seedling raising and cultivation are carried out, and rubus chingii can be obtained. The rubus-chingii seed breeding method is simple, economical and rapid, seed dormancy of the rubus chingii is broken, the breeding coefficient is increased, and a rapid breeding system of the rubus chingii is completed.

Description

technical field [0001] The invention belongs to breeding technology, in particular to a method for seed propagation of raspberry palmate. Background technique [0002] Palm leaf raspberry (Rubus chingii Hu) is a "raspberry" included in the "Chinese Pharmacopoeia". It belongs to the genus Rubus in the family Rosaceae. , has been widely used in pharmaceuticals, health care products, cosmetics and chemical industries. [0003] Recent studies have shown that raspberry palmate is a very promising plant resource. The roots, stems and leaves of raspberry palmate can be used as medicine; the immature green fruit can be used as traditional Chinese medicine after processing. The fruit tastes sweet and delicious. Sour, warm in nature, returns to kidney, bladder meridian, has the functions of nourishing kidney, strengthening essence, reducing urination, etc. It is used for diseases such as kidney deficiency, frequent urination, impotence, premature ejaculation, and spermatorrhea. The ...

Problems solved by technology

[0004] However, at present, most of the raw materials used in production come from the wild, and the standardized planting is in its infancy, and the seedlings are basically excavated from wild resources, transplanted and propagated by division, and the reproduction coefficient is low.

However, the seeds of Raspberry palmate are light in weight, small in size, deeply dormant, and difficult to reproduce. The rapid propagation system of Raspberry palmate seed has not been established, which is not conducive to the development of Raspberry palmate industry, and is not conducive to the study of its heterosis and genetic rules.

[0005] According to the "Journal of Yunnan Agricultural University" No. 3, 2007, Duan Xiu'an, Wang Shiyu, and Zhu Ying'an reported in the article "The Effects of Different Chemical Agents on the Germination Rate of Raspberry Seeds and the Plant Height of Seedlings". The highest germination rate is only 31%; "Economic Forest Research" 2001 No. 4 period, Fu Shunhua, Wu Jiasen, Yu Yongqing and Zhu Yuqiu etc. report in the article of " palm leaf raspberry seed characteristics and germination test research ", seed germination rate 50%, but it needs to be stored in low-temperature wet sand for 265 days, which takes a long time and requires long-term cultivation at low temperature in the refrigerator. In addition, the germination is not uniform, which increases the difficulty of seedling management including seedling transplantation, which is labor-intensive and time-consuming. This is extremely detrimental to the rapid propagation of palmate raspberry seeds
