Embodiment 1

[0025] A method for accelerating germination of gemu seeds, comprising the following steps:

[0026] (1) Degumming of lattice wood seeds

[0027] Put 200 grains of wood seeds into a plastic bag or a plastic bucket, add an equal volume of water until the water just submerges the seeds in the plastic bag or bucket, tie the bag or cover tightly, and store at 20-35°C Store for about 10 days, and the days of storage can be extended appropriately when the temperature is low. Wash off the mucus and impurities on the surface of the stacked retting seeds, and then dry them.

[0028] (2) Seed coat treatment

[0029] Rub the geranium seeds that have been removed from the epidermis on the cement floor along the end of the far radicle for 3-4 times (do not rub the end near the radicle), so as to just scratch the seed coat without damaging the endosperm of the seed. Slight damage to the endosperm will not affect the germination of the seeds, but it should not be excessively damaged.

Embodiment 2

[0037] A method for accelerating germination of gemu seeds, comprising the following steps:

[0038] (1) Degumming of lattice wood seeds

[0039] Put 200 grains of wood seeds into a plastic bag or a plastic bucket, add an equal volume of water until the water just submerges the seeds in the plastic bag or bucket, tie the bag or cover tightly, and store at 10-15°C Store for about 15 days, and the days of storage can be extended appropriately when the temperature is low. Wash off the mucus and impurities on the surface of the stacked retting seeds, and then dry them.

[0040] (2) Seed coat treatment

[0041] Rub the geranium seeds that have been removed from the epidermis on the cement floor along the end of the far radicle for 3-4 times (do not rub the end near the radicle), so as to just scratch the seed coat without damaging the endosperm of the seed. Slight damage to the endosperm will not affect the germination of the seeds, but it should not be excessively damaged.

Abstract

The invention discloses a germination accelerating method of erythrophleum fordii seeds, wherein the germination accelerating method comprises the following steps: (1) degumming of the erythrophleum fordii seeds: placing the erythrophleum fordii seeds into a container, adding water, soaking, then sealing the container, retting for a period of time, and then washing off mucus and impurities on thesurface of the retted seeds; (2) seed coat treatment: rubbing and damaging the erythrophleum fordii seeds having epidermal gum removed along one end far away from the radicle; (3) seed treatment: placing the erythrophleum fordii seeds having seed coat worn out into water, and soaking until the seeds are soaked and expanded; and (4) sowing and sowing post-management. The germination accelerating method of the erythrophleum fordii seeds comprises the steps of only needing to add clean water and retting for a period of time, washing off the mucus and impurities on the surface of the seeds, air-drying, wearing out the seed coats and soaking to expand. Compared with a hot water seed soaking method, the germination accelerating method saves labor and energy costs, and is easy to operate and master; compared with a concentrated sulfuric acid seed mixing method, the germination accelerating method has no danger and no pollution to the environment. The method can be used for accelerating the germination of the erythrophleum fordii seeds, has short seedling emergence time and neat seedling emergence, and has the germination rate reaching 99%.

Description

technical field [0001] The invention relates to the technical field of seedling breeding, in particular to a method for accelerating the germination of geranium seeds. Background technique [0002] Erythrophleum fordii is a precious material and greening tree species in tropical and subtropical regions of my country. It also has high medicinal value. Its structure is compact and solid, and it is extremely resistant to decay. Wood for furniture and handicrafts. Gemu seeds are hard seeds, with a layer of hard glue attached to the surface, which is extremely difficult to germinate in the natural state (it can be soaked in water for 1 year and 5 months without water swelling) (Chen Runzheng and Fu Jiarui, 1984), even if it germinates under accidental conditions (Insect pests or abrasion cause seed damage to absorb water and swell). Due to the influence of plant diseases and insect pests, light and other factors, the elimination rate at the seedling stage is also very high, which...
