Problems solved by technology

These cultivation methods take a long time, and the breeding is not easy to survive
Some existing purple magnolia tissue culture methods are carried out under closed aseptic conditions, the required cost is relatively large, and there is also the problem that the explants are easy to brown in tissue culture and the survival rate is not high, so they cannot be used for purple magnolia. Mass reproduction of magnolia

Abstract

The invention provides a magnolia liliiflora tissue culture method. The magnolia liliiflora tissue culture method is performed under open conditions, and the method comprises the following steps: performing sterilization and bacteriostasis on a magnolia liliiflora tissue culture field, selecting an explant, sterilizing and disinfecting the explant, performing primary culture on the explant, performing multiplication culture and performing rooting culture. The magnolia liliiflora tissue culture method is performed under open conditions and can be performed under the open conditions, and the cost is saved; according to sterilization of the magnolia liliiflora, the explant is not contaminated by bacteria, and the culture survival rate is improved; the explant is soaked by 2 percent of PVP, and the 2 percent of PVP is added into a culture medium, so that browning of the explant is lightened, and the survival rate is improved. The magnolia liliiflora tissue culture method is simple in operation, short in time, low in cost, high in survival rate and high in rooting rate, bottle transplanting in a short time can be realized, desirable traits of the original variety can be kept, and a foundation is laid for seed stock breeding and industrialized production.

Description

technical field [0001] The invention relates to the field of plant tissue culture, and mainly relates to a method for tissue culture of Magnolia magnolia. Background technique [0002] Purple magnolia, also known as magnolia and magnolia, is a unique plant in China. It is distributed in Yunnan, Fujian, Hubei, Sichuan and other places in China. It grows in areas with an altitude of 300 to 1600 meters, and generally grows on the edge of hillsides. Purple magnolia flowers are gorgeous and pleasant, fragrant and elegant, and they are beautiful alone or in clusters. They are excellent gardens and street greening plants, and they are also traditional Chinese flowers and traditional Chinese medicines. However, purple magnolias are not easy to transplant and maintain, and have been included in the "World It is a very precious flower and tree in the Red List of Plants of the IUCN. [0003] Now with the development of technology, many areas are carrying out the method of cultivating ...
