Embodiment 1

[0098] Embodiment 1: the quick seedling raising method of black rice tree tissue culture, concrete steps are as follows:

[0099](1) Take the strong branches with axillary buds of the black rice tree in the same year and remove the leaves as explants. First soak in 1wt% washing powder aqueous solution for 15 minutes, then gently scrub with a soft brush, and then put them under running water. Rinse for 2 hours, then soak in 70% alcohol for 60s on the ultra-clean workbench, rinse with sterile water for 3 times; then disinfect with 0.1% mercuric chloride for 10 minutes, rinse with sterile water for 8 times; blot the surface moisture Finally, cut the stem segment into a small segment with a length of 1 cm and 1 axillary bud.

[0100] (2) Inoculate the stem segments treated in step (1) into the induction medium, which is added with 2.0mg / L of ZT, 0.1mg / L of IBA and 0.2mg / L of WPM conventional medium at the same time. L's GA 3 ;Cultivate for 30 days under the conditions of tempera...

Embodiment 2

[0103] Embodiment 2: the quick seedling raising method of black rice tree tissue culture, concrete steps are as follows:

[0104] (1) Take the strong branches with axillary buds of the black rice tree in the same year and remove the leaves as explants. First soak in 1wt% washing powder aqueous solution for 12 minutes, then gently scrub with a soft brush, and then put them under running water. Rinse for 3 hours, then soak in 70% alcohol for 50s on the ultra-clean workbench, rinse with sterile water for 4 times; then disinfect with 0.1% mercury chloride for 15 minutes, rinse with sterile water for 6 times; blot the surface moisture Finally, the stem segment is cut into a small segment with a length of 1.3 cm and 1 axillary bud.

[0105] (2) Inoculate the stem segment treated in step (1) into the induction medium, which is added with 1.5mg / L ZT, 0.3mg / L IBA and 0.15mg / L L's GA 3 ;Cultivate for 35 days under the conditions of temperature 25°C, light intensity 2000Lux, and light ...

Embodiment 3

[0108] Embodiment 3: the fast seedling raising method of black rice tree tissue culture, concrete steps are as follows:

[0109] (1) Take the strong branches with axillary buds of the black rice tree in the same year and remove the leaves as explants. First soak in 1wt% washing powder aqueous solution for 15 minutes, then gently scrub with a soft brush, and then put them under running water. Rinse for 4 hours, then soak in 70% alcohol for 55s on the ultra-clean workbench, rinse with sterile water for 4 times; then disinfect with 0.1% mercuric chloride for 12 minutes, rinse with sterile water for 6 times; blot the surface moisture Finally, the stem segment is cut into a small segment with a length of 1.5 cm and 1 axillary bud.

[0110] (2) Inoculate the stem segment treated in step (1) into the induction medium, which is added with 1.0mg / L of ZT, 0.4mg / L of IBA and 0.15mg / L of WPM conventional medium at the same time. L's GA 3 ;Cultivate for 40 days under the conditions of te...

Abstract

The invention relates to plant tissue culture and discloses a tissue culture method for Vaccinium bracteatum Thunb, belonging to the field of plant cultivation. The method comprises the following four steps: explant sterilization; induction culture; propagation culture; and rooting culture. The method has the advantages of a high propagation rate, a fast growth rate and high hereditary stability, overcomes the problem of difficult breeding of Vaccinium bracteatum Thunb, can realize large-scale production and industrial large-scale supply of finished seedlings, protects excellent wild plant resources and brings about good economic values.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and relates to plant tissue culture, in particular to a method for tissue culture of black rice tree. Background technique [0002] Black rice tree, also known as Nanzhu, belongs to the evergreen shrub of Rhododendronaceae. It is mostly distributed in the southern part of my country. It is named after people steam black rice with its leaves every year on the third day of March and the eighth day of April in the lunar calendar.
