Abstract

The invention belongs to the field of medicament plantation, and concretely relates to a tissue culture method for Polygonatum cyrtonema. The invention also provides a composition for tissue culture of the Polygonatum cyrtonema, and a method for culturing the Polygonatum cyrtonema by using the composition. The method meets rapid and efficient Polygonatum cyrtonema seedling production requirementsby adopting young tubers of the Polygonatum cyrtonema as a material, adopting a plant tissue culturing technology, inducing calluses by the Polygonatum cyrtonema tubers, proliferating and differentiating the calluses and breaking the dormancy of Polygonatum cyrtonema buds through low-temperature treatment, and is suitable for large-scale production of the Polygonatum cyrtonema seedlings.

Description

technical field [0001] The invention belongs to the field of medicine planting, and in particular relates to a method for culturing Polygonatum polyflora tissue. Background technique [0002] Polygonatum cyrtonema is a Polygonatum plant of Liliaceae Polygonatum genus Polygonatum cyrtonema, Polygonatum sibiricum and Polygonatum kingianum coll. The rhizome of Polygonatum Polyflora has the traditional effects of invigorating qi and nourishing yin, invigorating the spleen, nourishing the lungs, and benefiting the kidneys. Soreness of the waist and knees, etc. Polygonatum multiflora has broad application prospects in anti-aging, regulating immunity, regulating blood lipids, improving memory, anti-tumor, and antibacterial. Polygonatum multiflora is distributed in Chongqing, Sichuan, Hunan, Hubei, Guizhou, Zhejiang and other provinces. [0003] The traditional propagation methods of Polygonatum multiflora include tuber and seed propagation. The tuber propagation of Polygonatum ...
