A kind of culture medium and propagation method of tissue culture rapid propagation of alum root blade

Abstract

The invention discloses a culture medium and a propagation method for tissue culture rapid propagation of leaves of heuchera micrantha. Through selection on an explants, selection on a basic culture medium and hormone combination in proper dosage, high-effective regeneration of a plant of the heuchera micrantha during the tissue culture is achieved. The propagation method is simple operation and low pollution rate, is high in success rate of regeneration of the plant, and is short in production period of grown-up seedlings.

Description

technical field

[0001] The invention relates to the technical field of plant tissue culture, in particular to a culture medium and a propagation method for rapid propagation of alum root leaf tissue culture. Background technique

[0002] Alum root ( Heuchera micrantha ) also known as Coral Bell, Saxifragaceae Alumia, loves the sun, is shade-tolerant, extremely cold-resistant, can grow normally at a low temperature of minus 30°C, has rich leaf colors and changeable leaf shapes, and is an excellent shade cover for colorful leaves plant. It has high ornamental value, good quality, high economic benefits, broad prospects for development and utilization, and extremely promising market prospects.

[0003] The conventional propagation method of alum root is branch propagation, the reproduction amount is limited, and affected by the season, it cannot meet the market demand.

[0004] There are many reports on alum root tissue culture, but there are the following problems: 1) The s...
