Embodiment Construction

[0019] The preferred embodiments of the present invention will be described in detail below.

[0020] The present embodiment trefoil adventitious root induction and propagation method, it carries out as follows:

[0021] (1) Induction of callus: rinse the leaves extracted from the Clover plant, sterilize with ethanol on the ultra-clean workbench and transfer to mercuric chloride for disinfection, then rinse with sterile water for 5 to 6 times, Cut into about 0.5cm×0.5cm in size, put it face up on the induction medium, and culture in the dark at 27±1°C for 30 days. In this step, the concentration of ethanol is 75%, soak the leaves for 30 seconds, transfer to 0.1% mercuric chloride for immersion and disinfection for 10 minutes, and the induction medium formula is MS+30g L -1 Sucrose+2.0mg·L -1 6-BA+0.2mg·L -1 NAA+6.5g·L -1 agar.

[0022] (2) Proliferation of callus: Cut the callus obtained in step (1) into small pieces on an ultra-clean workbench, inoculate on the prolifera...

Abstract

The invention discloses an induction and propagating method of a Tetrastigma hemsleyanum Diels et Gilg adventitious root, comprising the following steps of (1) induction of callus: cleaning leaves picked from a Tetrastigma hemsleyanum Diels et Gilg plant, sterilizing the leaves with ethyl alcohol on an ultra-clean workbench, then sterilizing the leaves with mercury bichloride, washing with sterile water, cutting, horizontally placing on an inducing medium with the right sides of the leaves being upward, and performing dark culture at 27+ / -1 DEG C; (2) propagation of the callus: cutting the callus obtained in step (1) into small pieces on the ultra-clean workbench, inoculating the cut callus with a propagation medium, and performing dark culture at 27+ / -1 DEG C; (3) induction of callus differentiation adventitious root: cutting the callus obtained in step (2) into small pieces on the ultra-clean workbench, inoculating the cut callus with an adventitious root induction medium, and performing dark culture at 27+ / -1 DEG C; (4) propagation of the adventitious root: cutting the adventitious root obtained in the step (3) into the set length on the ultra-clean workbench, inoculating the cut adventitious root with a liquid culture medium of propagation of the adventitious root, performing dark culture, and then performing light culture.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for inducing and propagating adventitious roots of P. trifoliate. Background technique [0002] Cliff climbing vine (Tetrastlg mahemsleyanum Dielset Gilg) is a unique rare medicinal plant in China. It is mainly used as medicine with tubers.
