Problems solved by technology

The most important thing about the above two methods is to establish a liquid suspension culture system, which requires obtaining a large number of embryogenic callus in good condition, but there are few related studies on the embryogenic callus of Luo Han Guo cells
[0004] Existing Momordica grosvenori embryogenic callus induction is mainly through seedlings after seed germination, part of the stem, leaves and roots of the plant are used as explants to induce embryogenic callus, but the stage of seed germination is It takes at least one month, which greatly lengthens the time to establish a liquid suspension culture system
Moreover, the induction rate of the existing embryogenic callus is also relatively low, and the performance of the induced cells in suspension culture is poor.

Abstract

The invention discloses a method of increasing suspendible cultured embryonic callus induction ratio of momordica grosvenori and belongs to the technical field of industrial biology. The method comprises the following steps: after disinfecting momordica grosvenori seeds, shelling the momordica grosvenori seeds and taking embryos; inoculating the momordica grosvenori seeds into an induction culture medium, the pH value of which is 5-7; and performing inductive culture for 15-21 days at 20-30 DEG C without illumination to obtain the embryonic callus of momordica grosvenori, wherein the inductive culture is composed of an MS basic salt culture medium, 25-35g / L of saccharose, 4-5g / L of agar, 80-120mg / L of inositol, 0.5-2mg / L of 6-BA, 0.5-1.5mg / L of NAA and 4-6g / L of glycine betaine. The induction rate of the suspendible cultured embryonic callus is 64-93.6%, the induction time can be shortened, and calluses which are good in state can be provided for large-scaled culture of momordica grosvenori cells.

Description

technical field [0001] The invention relates to a method for increasing the induction rate of embryogenic callus capable of suspension culture of Luo Han Guo, belonging to the field of industrial biotechnology. Background technique [0002] Luo Han Guo (Siraitia grosvenorii) is derived from the genus Momordica of Cucurbitaceae, and is a precious medicinal and edible plant unique to Guilin, Guangxi.
