Abstract

The invention discloses a method for obtaining an African daisy regeneration plant through inducing a somatic embryo. The method comprises the steps that an African daisy receptacle serving as an explant material is cultured in a somatic embryo inducing culture medium containing 6-benayl aminopurine, kinetin, thidiazuron, naphthylacetic acid, picloram and casein hydrolysate; the somatic embryo is induced; after the somatic embryo germinates, the somatic embryo is subjected to successive transfer culture in a differential medium; and the regeneration plant is obtained. According to the method, the African daisy receptacle serves as an explant, and the regeneration plant is obtained through a somatic embryo approach without a callus stage, so that a situation that explant is mutated due to dedifferentiation inducing callus regeneration can be avoided. By utilizing the method to perform African daisy tissue culture for seedlings, the culture procedure is simplified, the culture cycle is shortened, the quality of the seedlings is improved, and base materials are provided for a large number of high-quality seedlings by in-vitro propagation of African daisy and transgenic research.

Description

technical field [0001] The invention belongs to the technical field of gerbera tissue culture, and in particular relates to a method for obtaining regenerated gerbera plants by inducing somatic embryos. Background technique [0002] Gerbera jamesonii (Gerbera jamesonii), also known as gerbera flower, is native to South Africa and is a perennial herb of the Compositae genus Gerbera. It has the advantages of rich color, unique flower shape, high flower yield and long ornamental period. one. Since Gerbera chrysanthemum is self-fertile, the seedlings have great variation, and division propagation can maintain the original species characteristics without variation, but the seedlings are easily infected by diseases and insect pests during the propagation process, limited by seasons, and the propagation speed is slow, etc. The problem is that it is difficult to adapt to the needs of large-scale and factory production, and there are still problems such as virus accumulation and spe...
