Abstract

The invention relates to a factory breeding method for virus-free seedlings of salviae miltiorrhizae, in particular to a factory breeding method for wild species, cultivated species or varied speciesof salviae miltiorrhizae which is severe in quality degradation, lower in yield and short in resources, and belongs to the technical field of plant varieties breeding. The factory breeding method forvirus-free seedlings of salviae miltiorrhizae comprises the following steps: (1) selecting tender leaves or stem tips of the salviae miltiorrhizae to perform virus-free treatment; (2) culturing the tender leaves or stem tips of the salviae miltiorrhizae in an initial inducible-proliferation culture medium; (3) performing differentiation culture on salviae miltiorrhizae callus in a differentiationculture medium; (4) performing root induced culture on the seedlings of salviae miltiorrhizae in a root inducing culture medium; (5) exercising the seedlings of salviae miltiorrhizae; and (6) performing field transplanting for seedlings of salviae miltiorrhizae. The factory breeding method can realize quick and factory breeding for excellent salviae miltiorrhizae variety (system) or strain systemand cherish endangered salviae miltiorrhizae resources.

Description

technical field [0001] The invention relates to an industrial breeding method for virus-free seedlings of Salvia miltiorrhiza, in particular to an industrial breeding method for wild species, cultivated species or mutant species of Salvia miltiorrhiza with severe quality degradation, reduced yield and scarce resources, and belongs to the technical field of plant variety breeding. Background technique [0002] Danshen (Salvia miltiorrhza Bunge) is one of the bulk of traditional Chinese medicinal materials, which has a significant effect of promoting blood circulation and removing blood stasis, and is widely used in the treatment of coronary heart disease, angina pectoris, ischemic stroke and other diseases. At present, there are more than 100 compound Chinese medicines produced from Danshen as raw materials in my country, involving more than 100 enterprises, and there is a huge demand for high-quality Danshen medicinal materials. However, due to perennial excavation, the wild...
