Embodiment 1

[0021] Take 1Kg of MS Yunyan 87 seeds, immerse in a barrel containing 2Kg of tobacco seed oil, and stir constantly so that each tobacco seed is wrapped by tobacco seed oil. After 2 hours, use a nylon mesh bag with a pore size of 50 mesh to filter the tobacco seeds. Then put it into the washing machine to remove excess tobacco seed oil by centrifugation, transfer it to a cloth bag, and store it in an air-conditioned room with a temperature of 17±1°C and a relative air humidity of 40-45%. Before storage and within 1 year, 2 years, 3 years, 4 years, 5 years, and 6 years, 5g of seeds were taken out, and the standard method specified in YC / T20-1994 "Tobacco Seed Inspection Regulations" was used to determine the germination of the seeds. At the same time, the same batch of tobacco seeds stored under the same conditions that were not soaked in tobacco seed oil were used as a control to conduct experiments.

[0022] Experimental results such as figure 1 and figure 2 shown.

[0023...

Embodiment 2

[0025] Repeat application embodiment 1, difference is: the test material selected for use is the MSK326 seed after triggering 24 hours, respectively before storage and storage 3 months, 6 months, 9 months, 12 months, 15 months, 18 months After one month, the germination potential and germination rate of the seeds were measured.

[0026] Experimental results such as image 3 and Figure 4 shown.

[0027] The results showed that the germination potential of the control primed seeds dropped sharply to 83.0% in the 18th month of storage; the germination potential of the primed seeds soaked in tobacco seed oil remained above 90% after 18 months of storage. The germination rate of the control priming seeds decreased rapidly to 86.0% in the 18th month of storage; the germination rate of the priming seeds soaked in tobacco seed oil still reached 92.0% after 18 months of storage. It can be seen that soaking seeds in tobacco seed oil can also improve the storage resistance of tobacco...

Embodiment 3

[0029] The difference between repeating Example 1 and Example 2 is that the selected test material is the original species of safflower dajin yuan, and the storage temperature is 4±1°C.

[0030] Experimental result is identical with embodiment 1 and embodiment 2.

Abstract

The invention relates to a method for improving tobacco seed storage durability. The method for improving tobacco seed storage durability specifically comprises the following steps: pressing tobacco seed oil by adopting a physical pressing method; immersing tobacco seeds in the tobacco seed oil, performing uniform agitation and soaking the seeds for 2h; removing excessive oil on the tobacco seeds by adopting a centrifugation method, transferring the tobacco seeds into a storage container, and placing and storing the storage container a low-temperature and dry environment. By adopting the technical scheme, the fission rate of the tobacco seeds can be effectively reduced, the contact between the seeds and oxygen in air is reduced, the respiratory metabolism of the tobacco seeds is reduced and the storage durability of the tobacco seeds is improved; the tobacco seed oil does not influence the biological character of the tobacco seeds and the storage of the tobacco seeds is facilitated.

Description

technical field [0001] The invention belongs to the technical field of tobacco seed storage, and relates to a method for improving the storage resistance of tobacco seeds. Background technique [0002] During the storage of tobacco seeds, storage temperature, humidity and seed water content are the key factors affecting the storage effect. At present, the methods of reducing storage temperature and humidity, or super-drying of seeds are generally used to reduce the respiration and oxidation rate of seeds, slow down the fission rate, and improve the storage resistance of tobacco seeds. [0003] The storage temperature of improved tobacco seeds and induced tobacco seeds is generally 16-18°C, and the relative air humidity is generally 40-45%, which can control the moisture content of tobacco seeds below 7%. Under this condition, the storage period of tobacco seeds is generally 5 years, and the storage period of tobacco seeds after 28 hours is generally 1 year, and then the see...
