Germination method for schisandra sphenanthera seeds

Abstract

The invention discloses a germination method for schisandra sphenanthera seeds. The schisandra sphenanthera seeds are immersed in CuSO4 solution with mass-volume concentration of 1-10mg / L or the schisandra sphenanthera seeds are immersed in gibberellin aqueous solution with mass-volume of 200-300mg / L after being immersed in the CuSO4 solution and then are buried in sand soil for germination. According to the method, the cracking rate of the schisandra sphenanthera seeds can be obviously improved, and the cracking time can be greatly shortened; therefore, the germination rate and the seedling rate of the schisandra sphenanthera seeds are effectively increased, and the seedling emergence time is shortened. A result shows that the schisandra sphenanthera seeds treated by the method disclosed by the invention can be completely cracked after being buried in the sand soil for 50 days as quickly as possible; after the seeds are buried in the sand soil for 130 days, the cracking rate of the seeds can reach 67.67-94.33 percent; after the seeds are buried in the sand soil for 140 days, the germination rate of the seeds can be 68.67-93.33%; after the seeds are buried in the sand soil for 200 days, the average seedling rate of every 100 seeds is 70-92 percent; the germination method can be widely applied to breeding and cultivating the schisandra sphenanthera seeds.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and in particular relates to a method for breaking the dormancy of Schisandra chinensis seeds, shortening the germination time and increasing the germination rate. Background technique [0002] Schisandra sphenanthera (Schisandra sphenanthera Rehd.et Wils.) is a perennial deciduous woody vine of the genus Schisandra Michx. in the family Schisandraceae. Its dry and mature fruit is called Southern Schisandra. And other effects, were included in the "People's Republic of China Pharmacopoeia" (2010 edition). With the further development of the medicinal value of Schisandra chinensis, the market demand is increasing year by year. Wild Schisandra chinensis has been over-exploited, resulting in a sharp decline in wild resources. It has been listed as a national third-level protected wild medicinal species. [0003] In view of the fact that Schisandra chinensis is an important species of commonly...

AI Technical Summary

Problems solved by technology

Seed propagation is the main way for the population renewal of Schisandra chinensis, but its seed dormancy period is long, and the traditional seedling raising method takes 7 to 8 months to germinate, and the germination rate is low, which seriously restricts the population renewal. Therefore, breaking seed dormancy and shortening germination Time and improving the germination rate have become the key technologies for the seedling propagation of Schisandra chinensis seeds
