Embodiment 1

[0017] Embodiment 1: Jingui seed germination

[0018] (1) Seed treatment: During March to April, when the skin color of Jingui fruit changes from green to purple blue, collect the fruit from the tree body, soak the collected fruit in tap water for 24 hours, rub the pulp, Then soak the seeds in tap water for 24 hours, discard the seeds floating on the water surface, remove the seeds that sink to the bottom of the water, and dry them in the shade in a ventilated place indoors for 2-3 hours.

[0019] (2) Stratification treatment: Wet the river sand until it is kneaded into a ball by hand but no water seeps out. Place a layer of shade-dried seeds in a plastic dish for every 5 cm thick wet sand, and place a total of 3 layers , the top layer was covered with 10 cm of wet sand, and placed in a greenhouse at a room temperature of 20-22°C for 25 days.

[0020] (3) NaOH treatment: Take out the seeds stored in the sand for 25 days, rinse them with tap water, soak the seeds in 50% NaOH f...

[0023] Embodiment 2: Germination of silver osmanthus seeds

[0024] (1) Seed treatment: During March to April, when the skin color of Yinggui fruit changes from green to purple-blue, collect the fruit from the tree body, soak the collected fruit in tap water for 24 hours, rub the pulp, Then soak the seeds in tap water for 24 hours, discard the seeds floating on the water surface, remove the seeds that sink to the bottom of the water, and dry them in the shade in a ventilated place indoors for 2-3 hours.

[0025] (2) Stratification treatment: Wet the river sand until it is kneaded into a ball by hand but no water seeps out. Place a layer of shade-dried seeds in a plastic dish for every 5 cm thick wet sand, and place a total of 3 layers , the top layer was covered with 10 cm of wet sand, and placed in a greenhouse at a room temperature of 20-22°C for 25 days.

[0026] (3) NaOH treatment: Take out the seeds stored in the sand for 25 days, rinse them with tap water, soak the seed...

Abstract

The invention belongs to the technical field of ornamental horticultural plant breeding and particularly relates to a method for promoting the germination of sweet osmanthus seeds. The method is characterized in that the sweet osmanthus seeds are stratified in wet sand and treated with NaOH so that the dormancy of the sweet osmanthus seeds is broken and the germination of the sweet osmanthus seeds is accelerated. By adopting the method provided by the invention, the germination time of the sweet osmanthus seeds can be shortened effectively, and the cost can be reduced. The method is simple, is easy to operate and conforms to the production practice requirement.

Description

technical field [0001] The invention relates to the technical field of ornamental horticultural breeding, and more particularly relates to a method for rapidly breaking dormancy of osmanthus seeds and promoting germination of osmanthus seeds. Background technique [0002] Osmanthus fragrans Lour., also known as mountain osmanthus, rock osmanthus, and Jiulixiang, belongs to the evergreen broad-leaved small trees or shrubs of the genus Osmanthus in the family Oleaeeae. The height of the tree can reach 15 m. Fragrant and pleasant, it is the first choice tree species for greening in parks, courtyards, streets, roads, etc., and it is also one of the top ten traditional Chinese flowers. Therefore, the greening nursery stock market continues to maintain a large demand for sweet-scented osmanthus seedlings. Correspondingly, the propagation technology of sweet-scented osmanthus seedlings has also attracted long-term attention. [0003] Osmanthus osmanthus seeds have certain dehydrat...
