Embodiment 1

[0022] a. Knead the Hovenia dulcis fruit with dry peel, submerge the peeled seeds into the water, require the submerged seeds to be clearly separated from the floating seeds, use tools to remove the floating debris and seeds on the upper layer, and keep the lower layer Sinking seeds.

[0023] b. Disinfect the seeds obtained in step a with potassium permanganate solution at normal temperature, the concentration of potassium permanganate solution is 0.3g / L, and the disinfection time is 8min. Then wash it with clean water, then soak the seeds in warm water at 40°C for 35 minutes, and then soak the seeds in clean water for 2 days at room temperature.

[0024] c. Select the seeds with obvious imbibition, stabilize them with tweezers, make the seeds 0.25cm higher than the tweezers, and use a blade to cut downwards perpendicular to the seed ridge line to expose the endosperm.

[0025] d. Use absorbent cotton with a thickness of about 0.7cm as the medium and spread it on the bottom o...

Embodiment 2

[0027] a. Knead the Hovenia dulcis fruit with dry peel, submerge the peeled seeds in water, remove the floating debris and seeds in the upper layer, and keep the seeds in the lower layer;

[0028] b. Disinfect the seeds obtained in step a with potassium permanganate solution at normal temperature, the concentration of potassium permanganate solution is 0.5g / L, and the disinfection time is 12min. Then wash it with clean water, then soak the seeds in warm water at 50°C for 25 minutes, and then soak the seeds in clean water for 1 day at room temperature;

[0029] c. Select seeds with obvious imbibition, stabilize them with tweezers, make the seeds 0.15cm higher than the tweezers, and use a blade to cut along the direction of the ridge line to expose the endosperm.

[0030] d. Use absorbent cotton with a thickness of about 1 cm as a medium to spread on the bottom of the culture vessel. After the absorbent cotton is moistened with clear water, place the seeds whose shells have been...

Abstract

The invention discloses a method for physically breaking citrus trifoliata seed dormancy. The method includes the steps: a kneading a citrus trifoliate fruit with dry fruit peel; b disinfecting seedsacquired in the step a by potassium permanganate solution at the normal temperature, cleaning the disinfected seeds by clear water, soaking the cleaned seeds for 30 minutes in warm water of 40-50 DEGC, and soaking the seeds for 1-2d by clear water at normal temperature; c selecting obvious imbibition seeds, stabilizing the selected seeds by tweezers, enabling the seeds to be 0.15-0.25cm higher than the tweezers, and cutting seeds by a blade along the direction perpendicular to seed ridges downwards or horizontally cutting the seeds by the blade along the direction parallel to the seed ridgesto expose endosperm; d laying degreasing cotton on the bottom layer of a culture vessel, wetting the degreasing cotton by clear water, placing the seeds completely removed seed shells in the culture vessel, and placing the culture vessel into an illumination incubator to culture the seeds. According to the method, the germinating time of the citrus trifoliata seeds is short and about 3-4 days, effects are stable, and germination rate is stable and reaches 82.3%.

Description

technical field [0001] The invention relates to the technical field of forestry nursery stock cultivation. More specifically, the present invention relates to a method for promoting the germination of Hovenia dulcis seeds. Background technique [0002] Hovenia acerba Lindl. belongs to the genus Hovenia of the family Rhamnaceae. It is distributed in China, Japan, India and Korea. It is a rare tree species with great development value that combines fruit, medicine and wood : Its fleshy fruit stem contains multiple sugars, vitamins and essential amino acids for the human body, and can also be used as a raw fruit with high nutritional value; its fruit, seeds, leaves and roots can be used as medicine, with high medical value ; The tree material is hard, the texture is beautiful and easy to process, and it is an excellent building decoration material. [0003] Due to the dormancy phenomenon of Hovenia dulcis seeds, the germination rate under natural conditions is only 12%-20%, a...
