Abstract

The invention discloses a dendrobium candidum tissue culture plant hormone control method. The method comprises the following steps of: performing culture for 8 hours every day under the conditions that the humidity is 70 to 80 percent, the temperature is 23 to 28 DEG C and the illumination is 1,800 to 2,200LX; performing culture for 8 hours every day under the conditions that the temperature is 23 to 29 DEG C and the illumination is 1,000 to 1,400LX; performing culture for 8 hours every day under the conditions that the temperature is 23 to 25 DEG C and the illumination is 400 to 800LX; and after the dendrobium candidum is treated by the conventional sterilization program, sequentially culturing the dendrobium candidum through the following three stages: 1) callus culture; 2) adventitious bud induced culture; and 3) rooted seedling culture. The method has the advantages of greatly improving the dendrobium candidum tissue culture efficiency, optimizing the quality of the seedlings, shortening the culture period and providing a prerequisite for industrialized development of the dendrobium candidum.

Description

technical field [0001] The invention belongs to the technical field of seedling tissue culture, in particular to a method for plant hormone control in dendrobium officinale tissue culture. Background technique [0002] Dendrobium officinale is a perennial epiphytic herb of Orchidaceae. Born on the semi-shady rocks in the mountains at an altitude of 1600 meters, it likes warm and humid climates and semi-shady and semi-yang environments, and is not cold-resistant. Dendrobium can be divided into dozens of species such as yellow grass, nobile, and horsewhip. Dendrobium candidum is the best product of Dendrobium. It is named for its iron-green skin. Dendrobium officinale has unique medicinal value, and its stems are used as medicine. The name of the traditional Chinese medicine: Dendrobium, belongs to the yin-tonifying medicine in the tonic. Or spring-shaped, dried, the commodity is called earrings Dendrobium, has another name called Maple Dou. It is the most precious Chinese ...
