Problems solved by technology

In the previous work on planting resource investigation and breeding of Yale fir, it was found that the seed setting rate of Yale fir population was low, and the rate of seed abortion was as high as 80%. These conditions seriously restrict the standardized planting and production of Chinese fir.
On the other hand, due to the large differences in the plant attributes and physiological habits of seeds of different plants, the methods suitable for their seed germination are also different, so there is no method suitable for promoting the seed germination of Cedar chinensis in the prior art, especially for Cedar chinensis.

Embodiment 1

[0021] A method for promoting seed germination of Chinese fir chinensis, comprising the following steps:

[0022] (1) Seed selection: Select seeds that are oval in shape, brown and shiny on the front, light yellow on the back, wide in the middle or lower part of the seed wings, and have a thousand-grain weight of 130 g, mix them with water, and stir them thoroughly Remove floating empty and shriveled seeds, then add 0.2 g sodium hydroxide and 1.5 U alkaline lipase per 100 ml of clean water, soak for 12 hours, then scrub the seeds, and remove the sunken seeds to obtain plump seeds;

[0023] (2) Seed disinfection: soak the plump seeds obtained from the selection with 0.2% potassium permanganate solution for 12 min, and then rinse with distilled water for 4 times;

[0024] (3) Acceleration treatment: Soak the sterilized seeds in a 200 mg / L gibberellin solution at a temperature of 30°C for 48 h;

[0025] (4) Seed germination: The seeds after germination treatment were placed in a...

Abstract

The invention discloses a method for promoting the seed germination of Chinese fir chinensis, which comprises the following steps: (1) Seed selection: the selected shape is oval, the front is brown and shiny, the back is light yellow, and the middle part of the seed wing is wider or the middle and lower part Wider seeds with a thousand-grain weight of 130‑155 g, and then flotation to get plump seeds; (2) Seed disinfection: Soak the plump seeds obtained from the selection with potassium permanganate solution, and then rinse with distilled water; (3 ) Pregermination treatment: Soak the sterilized seeds with a concentration of 50‑300 mg / L gibberellin solution for 12‑48 h at a temperature of 25‑40 °C; (4) Seed germination: place the seeds after the germination treatment Placed in a Petri dish covered with 2 layers of filter paper, and then placed in an incubator for cultivation. This method can significantly improve the seed germination rate and quality of seedlings of Yale fir, shorten the germination time of the seeds, and provides a scientific and reliable method for the large-scale cultivation and standardized production of Yale fir.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for promoting seed germination of Chinese fir. Background technique [0002] Jiangnan oil fir (Keteleeria fortunei var. cyclolepis) belongs to Pinaceae (Pinaceae) Ketelieria (Keteleeria), is a unique local precious tree species in my country, now only scattered in Fujian, Zhejiang, Jiangxi, Hunan, Guangdong, Guangxi, Yunnan , Guizhou and other provinces. Jiangnan oil cedar has a tall and straight trunk, dense and dark green branches and leaves, dense material, beautiful color, durable, and the roots contain gum. It is often used as paper-making glue in folks. Therefore, Jiangnan oil fir is a very valuable timber tree species and landscaping ornamental trees. At the same time, due to its excellent characteristics such as strong stress resistance, fast growth and strong adaptability, Yale fir is an excellent tree species for mountain afforestation. ...
