Problems solved by technology

However, in the production of tobacco leaves, a large number of tobacco seeds are germinated, which is usually carried out in cloth bags. It is difficult to meet the light conditions. If the rubbing force is too small, the effect will not be achieved, and the seeds will not germinate
Therefore, the method effect of breaking seed dormancy in the traditional tobacco seed germination method is not ideal, making the germination rate lower

Embodiment 1

[0020] Tobacco seed germination method, comprises the following steps:

[0021] (1) Seed soaking: Pour 1 kg of tobacco seeds directly into a container containing a gibberellin solution with a concentration of 90 mg / kg. The amount of the gibberellin solution must ensure that the seeds are completely immersed in it, and the temperature is kept at 20-28°C. 72 hours;

[0022] (2) Cleaning: After soaking the seeds, pour off the solution, wash the seeds twice with clean water, then put the seeds into cloth bags, tie the mouth, and dry them with a dryer;

[0023] (3) Disinfection: Disinfect the seed bag in 1% copper sulfate solution for 10 minutes, control the Chinese medicinal liquid in the cloth bag, rinse the seed bag twice with water at 25-28°C, and dry it with a dryer after each rinse ;

[0024] (4) Germination: After disinfection and drying, put the seed bag on the wooden pole of the cultivation room or hang it in the cultivation room, keep the temperature at 28-30°C, and rin...

Abstract

The invention discloses a tobacco seed germinating method, which utilizes gibberellin solution to break the seed dormancy, and promotes the germination of tobacco seeds by steps of seed soaking, cleaning, disinfecting, germinating and the like to improve the germination rate and the germinating uniformity and achieve the aims of uniform and healthy seedlings, and improvement of breeding quality.

Description

technical field [0001] The invention relates to a method for accelerating germination of tobacco seeds, in particular to a method for accelerating germination of tobacco seeds by using gibberellin to break dormancy. Background technique [0002] Due to the dormancy period of the new tobacco seeds propagated in the same year, seed dormancy needs to be broken for germination. Generally, light induction is required to break seed dormancy. Seed rubbing technology can also be used to break seed dormancy. In the traditional method of accelerating germination, after soaking the seeds at 25-28°C, rub the seeds, and then enter the state of accelerating germination to promote emergence. However, in the production of tobacco leaves, a large number of tobacco seeds are germinated, which is usually carried out in cloth bags. It is difficult to meet the light conditions. If the rubbing force is too small, the effect will not be achieved, and the seeds will not germinate. Therefore the m...
