Embodiment 1

[0028] The method for the quick germination of the maple seed of the present embodiment comprises the steps:

[0029] (1) Pretreatment of maple samara:

[0030] Collection time: late September;

[0031] Collection method: Use long branch scissors to cut the yellow-brown samara that is close to maturity, put it in a paper bag, and store it at room temperature;

[0032] Postharvest treatment: rinse with running water for 10 minutes; soak in 5‰ potassium permanganate for 30 minutes, then wash with sterile water for 3 times, wipe the excess water on the surface with gauze, put the seeds in a 500ml tissue culture bottle, There are 3 layers of filter paper moistened with sterile water. The seeds are placed on the filter paper and sealed with an air-permeable film. 30 Acer spp. seeds are placed in each bottle, and 30 Acer ℃ environment, during which sterile water can be added to the surface of the filter paper on the ultra-clean table to ensure that the surface of the filter paper ...

Abstract

The invention relates to a method for promoting rapid germination of seeds of acer griseum, and a seedling-raising method of the acer griseum, belonging to the technical field of forest tree breeding. The method for promoting the rapid germination of the seeds of the acer griseum comprises the following steps: (1) soaking samara of the acer griseum into a potassium permanganate solution for 30-60min, then washing the samara with sterile water, putting the washed samara into a sterile container, and sealing the container by using a breathable film; (2) taking out embryo of the samara, obtained in the step (1), and soaking the embryo into a gibberellin solution for 2-3h; (3) carrying out bactericidal treatment on the embryo soaked in the step (2), and then culturing for promoting germination. The obtained germinating seeds are raised into seedlings in cultivating bags or cultivating holes. After the method is adopted, the seeds of the acer griseum are rapid in germination speed and high in germination rate; the methods provided by the invention are convenient to operate and easy to popularize and apply, and are free of special nursing, thus having good application prospect.

Description

technical field [0001] The invention relates to a method for rapid germination and seedling raising of Acer spp. seeds, and belongs to the technical field of tree breeding. Background technique [0002] Blood skin maple (Acer griseum) is a deciduous tree belonging to the Aceraceae family, endemic to China and an endangered species. The reddish-brown bark of the blood-skinned maple often peels off in curled paper-like flakes, which is rather peculiar, and the color of the leaves after autumn is bright red, so it has a very high ornamental value. The seed setting rate of the mother tree of the maple is low, the seeds are rare resources, and the empty shell rate is extremely high. In view of the two factors of the hard mechanical barrier of the pericarp and the physiological dormancy of the seed embryo, the germination rate is extremely low, and there is no germination treatment under natural conditions. It takes more than 2 years for the seeds to germinate, during which a lar...
