Problems solved by technology

In general, it takes 3 months of stratification to accelerate germination before dormancy can be released, but the germination time is longer (under field conditions, it usually takes 45d-50d to reach a germination rate of more than 70%) and the germination is irregular, which often causes a great waste of seed resources. , limiting the scale production of Nannan seedlings

Embodiment 1

[0022] In late November 2015, when the fruit of Minnan was purple-black, it was collected. Soak the collected fresh Minnan fruit in clean water for 2 days, and change the clean water once a day. Then rub the pulp manually, and drop a small amount of detergent in the water to remove the grease when rubbing the pulp. Filter out impurities to obtain pure seeds, and place them in a ventilated place indoors to dry in the shade. Put the seeds into a cloth bag, put them in a refrigerator at 4°C, and keep the humidity of the refrigerator at 80%; flip the seeds once a week.

[0023] In January 2016, soak the refrigerated seeds in clean water for 2 hours to fully absorb water and swell; then fully stir the seeds in clean water, and then let them stand to remove unfulfilled seeds and impurities floating on the water surface. Soak the seeds in 3 mg / L naphthalene acetic acid + 3 mg / L indole butyric acid for 24 hours, then soak them in 0.5% potassium permanganate solution for 1 min, remov...

Embodiment 2

[0025] It was collected in early December 2015 when the fruit of Minnan was purple-black. Soak the collected fresh Minnan fruit in clean water for 3 days, and change the clean water once a day. Then rub the pulp manually, and drop a small amount of detergent in the water to remove the grease when rubbing the pulp. Filter out impurities to obtain pure seeds, and place them in a ventilated place indoors to dry in the shade. Put the seeds into a cloth bag, put them in a refrigerator at 4°C, and keep the humidity of the refrigerator at 85%; flip the seeds once a week.

[0026] In February 2016, soak the refrigerated seeds in clean water for 3 hours to make them fully absorb water and swell; then fully stir the seeds in clean water, and then let them stand to remove unfulfilled seeds and impurities floating on the water surface. Soak the seeds in 4 mg / L naphthalene acetic acid + 4 mg / L indole butyric acid for 22 hours, then soak them in 0.5% potassium permanganate solution for 1 ...

Embodiment 3

[0028] It was collected in early December 2015 when the fruit of Minnan was purple-black. Soak the collected fresh Minnan fruit in clean water for 3 days, and change the clean water once a day. Then rub the pulp manually, and drop a small amount of detergent in the water to remove the grease when rubbing the pulp. Filter out impurities to obtain pure seeds, and place them in a ventilated place indoors to dry in the shade. Put the seeds into a cloth bag, put them in a refrigerator at 4°C, and keep the humidity of the refrigerator at 90%; flip the seeds once a week.

[0029] In March 2016, soak the refrigerated seeds in clean water for 4 hours to make them fully absorb water and swell; then fully stir the seeds in clean water, and then let them stand to remove unfulfilled seeds and impurities floating on the water surface. Soak the seeds in 5 mg / L naphthalene acetic acid + 5 mg / L indole butyric acid for 20 hours, then soak them in 0.5% potassium permanganate solution for 1 min...

Abstract

The invention discloses a method for promoting germination of phoebe bournei seeds. The method comprises the steps of seed collection, seed coming-off, seed storage, seed selection and seed soaking. Ripe phoebe bournei fruits are collected and subjected to peeling to make seeds come off, and seeds are stored in a refrigerator, selected, soaked in acetic acid and indolebutyric acid, and then subjected to breeding and management so that germinated phoebe bournei seeds can be obtained. According to the method, long-time stratification is not needed, seed dormancy can be broken simply by soaking the seeds in naphthylacetic acid and indolebutyric acid solution with proper concentration, seed germination is accelerated, and germination rate is increased; compared with traditional methods that hormone pharmaceutical treatment is not adopted at all, the method has the advantages that after soaking the phoebe bournei seeds in the naphthylacetic acid and indolebutyric acid solution, seeds can be germinated earlier, germination rate is increased by 95% or above, buds come out neatly, and economic benefits, social benefits and ecological benefits are high.

Description

technical field [0001] The invention relates to the technical field of plant seed dormancy relief, in particular to a method for promoting the germination of Nannan seeds. Background technique [0002] Phoebe bournei is an evergreen tree belonging to Lauraceae, which is a unique tree species in China and a national second-class wild protected plant. Its trunk is straight, its wood structure is fine and dense, its cut surface is smooth and beautiful, and it has a fragrance. It is a precious material for high-grade buildings, furniture, carvings and precision wood models. Minnan is mainly propagated by seeds, and the fruit is obviously large and small. Due to comprehensive factors such as human deforestation, its own biological characteristics and the natural environment, the resources of Nannan are close to depletion. [0003] There is obvious phenomenon of different years of fruiting in Nannan, the seeds are not resistant to storage and have dormancy characteristics, and t...
