Problems solved by technology

The conventional propagation methods of golden leaf tortoiseshell holly include cutting propagation and grafting propagation. The propagation cycle of cutting propagation is about 1 year, the survival rate is about 90%, and the reproduction coefficient is less than or equal to 1; the propagation cycle of grafting propagation is more than one year, and the survival rate is 60%. %-80%, the reproduction coefficient is less than or equal to 1, due to its slow reproduction speed, low reproduction coefficient and survival rate limit its popularization and application

Embodiment 1

[0030] Select the young stems with axillary buds of the golden-leaf tortoiseshell holly as explants, place the explants under running water and rinse them repeatedly for 1 hour, add an appropriate amount of detergent to soak and wash them for 3 times, shake them while soaking, and rinse them clean Then move to the ultra-clean workbench for the next step of disinfection. Disinfection treatment is as follows: soak the explants in 75% alcohol for 20 seconds, rinse and shake the explants with sterile water for 3 times, each time for 7 minutes; then transfer to 0.1% mercury chloride (HgCl 2 ) for 8 minutes, rinsed repeatedly with sterile water, and then blotted the moisture on the surface of the explants with sterile paper.

[0031] Inoculate the sterilized explants of the holly-leaved tortoise shell on the primary medium, the formula of the primary medium is: MS+ZT 0.5mg / L+NAA0.1mg / L+sucrose 25mg / L+agar 7mg / L, pH value 5.6 . The culture conditions are: a sterile culture room wit...

Embodiment 2

[0039] Select the young stems with axillary buds of the golden-leaf tortoiseshell holly as explants, place the explants under running water and rinse them repeatedly for 1 hour, add an appropriate amount of detergent to soak and wash them for 3 times, shake them while soaking, and rinse them clean Then move to the ultra-clean workbench for the next step of disinfection. Disinfection treatment is as follows: soak the explants in 75% alcohol for 20 seconds, rinse and vibrate the explants 5 times with sterile water for 6 minutes each time; then transfer to mercuric chloride (HgCl 2 ) for 9 minutes, rinsed repeatedly with sterile water, and then blotted the moisture on the surface of the explants with sterile paper.

[0040] Inoculate the sterilized Ilex aureus explants on the primary culture medium, the formula of the primary culture medium is: MS+ZT1.0mg / L+NAA0.1mg / L+sucrose 25mg / L+agar 7mg / L, pH value 5.8 . The culture conditions are: a sterile culture room with a temperature...

Embodiment 3

[0048] Select the young stems with axillary buds of the golden-leaf tortoiseshell holly as explants, place the explants under running water and rinse them repeatedly for 1 hour, add an appropriate amount of detergent to soak and wash them for 3 times, shake them while soaking, and rinse them clean Then move to the ultra-clean workbench for the next step of disinfection. Disinfection treatment is as follows: soak the explants in 75% alcohol for 20 seconds, rinse and vibrate the explants 5 times with sterile water, and rinse for 5 minutes each time; then transfer to mercury chloride (HgCl 2 ) for 8 minutes, rinsed repeatedly with sterile water, and then blotted the moisture on the surface of the explants with sterile paper.

[0049] Inoculate the sterilized Ilex aureus explants on the primary culture medium, the formula of the primary culture medium is: MS+ZT 0.8mg / L+NAA0.1mg / L+sucrose 25mg / L+agar 7mg / L, pH value 5.7 . The culture conditions are: a sterile culture room with a ...

Description

technical field [0001] The present invention relates to the field of holly propagation, in particular to a tissue culture propagation method of golden leaf tortoise shell holly. Background technique [0002] The golden-leaf tortoiseshell holly is a colorful-leaved plant of the holly genus in the Ilex family. It has the characteristics of evergreen, low temperature resistance, and low and compact plants. It is a new variety of colorful leaves introduced from abroad in my country in recent years. The old leaves are dark green and shiny, and the new leaves are golden yellow, with extremely bright color. In recent years, tortoiseshell holly has been in great demand in the greening industry at home and abroad, so its propagation speed should be accelerated to meet its increasing market demand. The conventional propagation methods of golden leaf tortoiseshell holly include cutting propagation and grafting propagation. The propagation cycle of cutting propagation is about 1 year, ...
