Problems solved by technology

We have found through research that using different concentrations of growth regulators alone has no obvious effect on promoting the germination of Prunus japonica seeds, and the germination cycle is long
In conventional seedling raising methods, the seeds are only used once, that is, one seed can only cultivate one seedling, and the limited seed resources cannot be fully utilized.

Embodiment 1

[0049] (1) Preparation of culture substrate:

[0050] The culture substrate is river sand. One week before use, spray and soak the culture substrate with 0.5% carbendazim solution, carry out disinfection treatment, and dry it under natural conditions for later use;

[0051] (2) Preparation of seeds:

[0052] Soak the recovered golden plum fruit outdoors for a few days, rub the peel and pulp off, rinse the seeds with clean water, and remove the obvious seeds of diseases and insect pests, and use 0.1% KMnO 4 Soak and disinfect for 30 minutes, rinse with clean water for germination;

[0053] (3) Germination culture:

[0054] Such as figure 1 As shown, the culture container is a disposable lunch box with a length (17.2cm)×width (11.7cm)×height (7cm) and a capacity of 1000ml, and a 2-2.5cm-thick layer of 15.0% water content is spread in the lunch box. River sand, put the seeds evenly on the surface of the river sand, lightly press it to make it contact with the wet sand, cover...

Embodiment 2

[0070] (1) Preparation of culture substrate: the same as in Example 1;

[0071] (2) Preparation of seeds: same as Example 1;

[0072] (3) Germination culture:

[0073] Spread 4cm thick river sand with a water content of about 15.0% in the lunch box, bury the soaked seeds in the sand for 1cm, spread them flat, and place them in an artificial climate incubator for cultivation. The cultivation conditions are: 25°C Constant temperature, periodic light (light intensity 3000lx, light time 12 h day - 1 ), according to the water loss of the medium, add water appropriately to keep the water content at about 15.0%.

[0074] Results: Germination began 38 days after sowing, reached the peak of germination at 280 days, and ended at 350 days. The germination rate was 85.0%, and the average germination time was 193.7 days. The germination process was irregular and long.

Embodiment 3

[0076] (1) Preparation of culture substrate: the same as in Example 1;

[0077] (2) Preparation of seeds: Same as Example 1;

[0078] (3) Seed soaking:

[0079] Put the prepared seeds in a clean water basin, add 100mg / L indole acetic acid (IAA) treatment solution, submerge the seeds, soak the seeds at room temperature for 24 hours and then wash them;

[0080] (4) Germination culture:

[0081] Except that the water content of the river sand is kept at about 20.0%, the rest of the cultivation method is the same as step (3) of Example 2.

[0082] Results: Germination began 60 days after sowing, reached the peak of germination at 280 days, and ended at 350 days. The germination rate was 56.7%, and the average germination time was 232.7 days. The germination rate was low, and the germination was irregular and extremely slow.

Abstract

The invention discloses a method for promoting germination and repeated propagation of garcinia paucinervis seeds. The method can greatly shorten seedling period, increase the seedling yield of seeds and reduce seedling costs by comprehensively controlling various germination factor conditions of the garcinia paucinervis seeds, breaking seed dormancy, increasing a germination speed, uniformity and a germination rate of the seed, greatly promoting germination of the seeds, and also raising seedlings in multiple batches based by using a characteristic that the seeds can germinate repeatedly. The garcinia paucinervis seeds, having an original germination rate of 85.0% in 350 days, have an initial germination rate of up to 95.0% in 30 days after being processed by the method; the recycled seeds have the germination rate of up to 83.3% or more through germination acceleration for 60 days, and are fast and uniform in germination. The method lays a good foundation for efficient propagation of garcinia paucinervis seedlings, and has a very positive impact on regeneration and sustainable utilization of rare and endangered plant resources.

Description

technical field [0001] The invention belongs to the field of biotechnology, in particular to a method for promoting rapid and repeated germination of Prunus japonica seeds into seedlings. Background technique [0002] Golden Lee ( Garcinia paucinervis ) is the genus Garcinia (Guttiferae) of the family Garcinia (Guttiferae) Garcinia ) tree, named for its trunk cross-section, which can see the golden wire-like rays radiating from the inside to the outside. It is mainly distributed in the limestone karst landform mountains in the west and south of Guangxi and the southeast of Yunnan at an altitude of 194-830m. It is a unique and precious tree species in Shishan. species. "Chinese herbal medicine" records that the branches, leaves and bark of Jinsi plum can be used as medicinal materials, which have the effects of clearing away heat, detoxifying, and reducing swelling. It is also "one of the top five hardwoods in Guangxi". It has hard wood, dense structure, straight texture...
