Abstract

The invention relates to a separation and culturing method of Sinkiang saussurea protoplast, comprising four steps of culturing of sterile saussurea involucrate seedlings, inducement and differentiation of embryonic callus, separation and purification of plasmogen and culturing of the protoplast which are all applicable to the separation and culturing of the Sinkiang saussurea involucrate protoplast. The invention has simple and easily-operated method and lower requirements on the equipment and culturing conditions; in addition, the enzymolysis method is practical, the conditions for cell wall removal are mild, and the separated protoplast has high yield and strong activity, and is easy for the cultuing of the saussurea involucrate protoplast and a plant regeneration, thus laying the foundations for the culturing and fusing of the protoplast as well as the germplasm resource innovation of the Sinkiang saussurea involucrate and the research of transgenic saussurea involucrate.

Description
