Problems solved by technology

And the sowing time of sweet-scented osmanthus can be around October in autumn, but the sweet-scented osmanthus seeds harvested that year have not yet broken dormancy and cannot germinate and grow seedlings
The conventional method of breaking dormancy is to germinate the sweet-scented osmanthus seeds that have been stored in mixed sand through wet sand treatment. This method takes a long time and has a low germination rate; But still exist the low germination rate, the relatively long problem of time, so further study a kind of method that breaks the dormancy of sweet-scented osmanthus seeds fast is very necessary

Embodiment 1

[0016] A method for breaking dormancy of sweet-scented osmanthus seeds, the method may further comprise the steps:

[0017] (1) Seed selection: During April to May, the osmanthus seeds can be harvested when the peel of the osmanthus seeds gradually changes from green to purple blue. After harvesting, sprinkle water and stack retting, remove the pulp, dry the seeds in the shade, and store them in sand. Select the harvested plump seeds and dry them in a ventilated shade;

[0018] (2) Wash the selected seeds with clean water first, then soak them in 0.5% potassium permanganate solution for 1 hour, wash them with clean water and dry them in the air;

[0019] (3) Treat the osmanthus seeds obtained in step (2) with cold plasma generated by atmospheric pressure dielectric barrier discharge. The time for plasma treatment of seeds is 60 seconds. The power supply of the dielectric barrier discharge is a high-frequency high-voltage power supply with a frequency range of 4kHz, the volta...

Embodiment 2

[0023] A method for breaking dormancy of sweet-scented osmanthus seeds, the method may further comprise the steps:

[0024] (1) Seed selection: During April to May, the osmanthus seeds can be harvested when the peel of the osmanthus seeds gradually changes from green to purple blue. After harvesting, sprinkle water and stack retting, remove the pulp, dry the seeds in the shade, and store them in sand. Select the harvested plump seeds and dry them in a ventilated shade;

[0025] (2) Wash the selected seeds with clean water first, then soak them in 1% potassium permanganate solution for 2 hours, wash them with clean water and dry them in the air;

[0026] (3) Treat the osmanthus seeds obtained in step (2) with cold plasma generated by atmospheric pressure dielectric barrier discharge. The time for plasma treatment of seeds is 80 seconds. The power supply of the dielectric barrier discharge is a high-frequency high-voltage power supply with a frequency range of 4kHz, the voltag...

Embodiment 3

[0030] A method for breaking dormancy of sweet-scented osmanthus seeds, the method may further comprise the steps:

[0031] (1) Seed selection: During April to May, the osmanthus seeds can be harvested when the peel of the osmanthus seeds gradually changes from green to purple blue. After harvesting, sprinkle water and stack retting, remove the pulp, dry the seeds in the shade, and store them in sand. Select the harvested plump seeds and dry them in a ventilated shade;

[0032] (2) Wash the selected seeds with clean water first, then soak them in 1% potassium permanganate solution for 1.5 hours, wash them with clean water and dry them in the air;

[0033] (3) Treat the osmanthus seeds obtained in step (2) with the cold plasma generated by atmospheric pressure dielectric barrier discharge. The plasma treatment time for the seeds is 70 seconds. The power supply for the dielectric barrier discharge is a high-frequency high-voltage power supply with a frequency range of 5kHz, th...

Abstract

The invention discloses a method for breaking sweet-scented osmanthus seed dormancy. The method comprises the following steps of seed selection, seed soaking treatment, plasma treatment, comprehensive treatment by gibberellin and hydrogen peroxide, low-temperature stratifcation treatment and the like. According to the method disclosed by the invention, proper frequency, voltage and treatment time of the plasma treatment are selected so that the later low-temperature treatment time is shortened. As the gibberellin and the hydrogen peroxide are applied to the comprehensive treatment of the seed, a substance inhibiting seed germination is effectively broken, and the time for breaking the dormancy is shortened.

Description

technical field [0001] The invention relates to a method for rapidly breaking the dormancy of sweet-scented osmanthus seeds. Background technique [0002] Osmanthus fragrans is one of my country's top ten traditional famous flowers, and it is also one of the most precious flowers and trees in modern urban greening. It has beautiful trees, luxuriant foliage, green leaves, and evergreen all year round. It is especially attractive with its fragrance of flowers. city ​​flower. The demand for osmanthus is increasing day by day now, and the rapid reproduction of osmanthus is a problem that cannot be ignored. [0003] Seed dormancy and low temperature deposition Like many woody plants, osmanthus seeds also have a long dormancy period. The osmanthus seeds that are now harvested basically do not germinate that year, and only germinate in the second spring after winter dormancy. During such a long dormant period of several months, the seeds may suffer unnecessary losses due to ins...
