Problems solved by technology

The method of the invention uses Lycoris bulbs as explants to induce culture to produce Lycoris. This method needs to be at the cost of losing Lycoris bulbs. For Lycoris germplasm resources that are gradually scarce, this method is more risky

Abstract

The invention discloses a method for callus of lycoris radiate by using flower stalks, comprising the following steps: taking the flower stalks of the lycoris radiate after being sterilized; inoculating in induction culture medium, cultivating for 28-32 d in sunshine, then moving to a dark environment, and cultivating for 88-92 d, wherein the induction culture medium comprises 2.0-2.5 mg / L of 2,4-D and 1.5-2.5 mg / LBA of MS culture medium, and the MS culture medium comprises sugarcane of which concentration is 30-60 g / L and agar of which concentration is 5-8 g / L and pH is 5.6-5.8. The invention adopts the flower stalks of the lycoris radiate as the exophyte, produces the callus of the lycoris radiate through cultivating in the induction culture medium, cannot be at the cost of consuming the bulbs, and effectively protects the genetic resources of the rare lycoris radiate which has good quality.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture, in particular to a method for inducing lycoris callus by using pedicel. Background technique [0002] Lycoris radiata is a famous bulbous flower native to my country, which has both ornamental and medicinal value. The natural reproduction rate of Lycoris is low, and the juvenile period of bulbs is as long as 5-6 years. In recent years, due to the excavation of the medicinal value of Lycoris, the resources of Lycoris have been collected in large quantities, and the protection of wild resources is facing a crisis. [0003] In 1979, Koyama first reported the tissue culture of Lycoris, and the research on tissue culture of Lycoris plants in my country has been more than 20 years. The domestic research mainly focuses on exploring different explants of Lycoris, such as bulbs, bulbs, embryos, etc. to induce Plantlets were obtained from adventitious buds or callus. Inducing adventitious bu...
