Rapid rhizoma polygonati propagation technology method

Abstract

The invention provides a rapid rhizoma polygonati propagation technology method. The method comprises the following steps: breaking seed dormancy by changing temperature treatment and hormone treatment, performing induction in vitro to culture callus by utilizing seeds subjected to dormancy breakage as materials, performing differentiation culture and root induction, and performing vegetative propagation on rhizoma polygonati seedlings. By adoption of the technology, the rhizoma polygonati propagation factor can be greatly improved, the production period is shortened, the sowing quantity is reduced, and the production cost is reduced.

Description

technical field

[0001] The invention belongs to the technical field of bioengineering, and in particular relates to a technical method for rapid propagation of the traditional Chinese medicine Rhizoma Polygonatum. Background technique

[0002] Polygonatum is a perennial herb of the Liliaceae Polygonatum. There are about 41 species in the world, and about 35 species in my country. According to the "Chinese Pharmacopoeia 2010 Edition", the medicinal products in my country are mainly Rhizoma Polygonatum distributed in the north, Polygonatum Polygonatum distributed in the Yunnan-Guizhou Plateau and Polygonatum multiflora in the south of the Yangtze River. It has a history of more than 2,000 years for medicinal purposes. Because of its wide distribution, strong adaptability, high medicinal value, and both medicine and food, it has attracted more and more attention, especially as a functional food, it has a very broad application prospect.

[0003] Polygonatum mainly contains po...
