Problems solved by technology

However, in the production of Terminalia terminalia seedlings, all the peels will be removed. On the one hand, it will increase the production cost. On the other hand, because the endocarp of Terminalia terminalia is relatively hard, it has a certain degree of adhesion with the seed kernel, and it is easy to damage the seeds during the removal process. Therefore, in the production It is unrealistic to cultivate seedlings by completely removing the peel (shell)

Embodiment 1

[0018] A kind of preparation method of terminalia zebra seed initiator comprises the following steps: dissolving PEG-6000 and sodium chloride in water, heating to 35-40°C, stirring at 600rpm for 20min, adding sodium lauryl sulfate and Copper chloride, stir evenly, store at 35-40°C.

[0019] The mass concentration of PEG-6000 in the initiator is 5%, the mass concentration of sodium chloride is 0.01%, the mass concentration of cupric chloride is 0.005%, and the mass concentration of sodium lauryl sulfate is 0.2%.

[0020] The usage method of this initiator: get the seed with pericarp, remove exocarp, mesocarp and ≤5% endocarp, soak seed in initiator (25~28 ℃) for 5 days, take out seed, make it under room temperature Slowly dry back to original level.

Embodiment 2

[0022] A kind of preparation method of terminalia seed initiator, comprises the following steps: dissolving PEG-6000 and sodium chloride in water, heating to 35~40 ℃, stirring at 1000rpm rotating speed for 10min, then adding sodium lauryl sulfate and Copper chloride, stir evenly, store at 35-40°C.

[0023] The mass concentration of PEG in the initiator is 20%, the mass concentration of sodium chloride is 0.02%, the mass concentration of copper chloride is 0.003%, and the mass concentration of sodium lauryl sulfate is 0.1%.

[0024] The usage method of this initiator: take the seed with pericarp, remove the exocarp, mesocarp and ≤5% endocarp, soak the seed in the initiator (25~28°C) for 4 days, take out the seed, make it under room temperature Slowly dry back to original level.

Embodiment 3

[0026] The difference between embodiment 3 and embodiment 1 is:

[0027] The soaking temperature of the seeds in the initiator is 35-40°C.

Abstract

The invention discloses the preparation and application method of a seed initiator of Terminalia zebrae. The invention introduces sodium lauryl sulfate and copper chloride into PEG and sodium chloride solution, and strictly controls the preparation parameters to affect the PEG According to the spatial conformation, an initiator that can effectively shorten the germination time of Terminalia zebrascens seeds, increase the germination rate and realize synchronous germination of seeds can be successfully obtained on the basis of only partially removing the endocarp. By adopting the method of the invention, the average germination time of the terminalia twig seeds is shortened by more than 44%, the germination rate is increased by more than 47%, and the synchronization index is increased by more than 19%.

Description

technical field [0001] The invention specifically relates to the preparation and application method of a seed initiator of Terminalia eucalyptus. Background technique [0002] Terminalia catappa L. is a tall tree of the genus Myrobalan in the family Junzike, with oval fruit, soft woody exocarp, hard woody endocarp, and a seed inside. In production, it is mostly propagated by seeds, and it generally takes more than 60 days after sowing to enter the peak germination period, which takes a long time. The longer germination time makes the seed germination process susceptible to the influence of various environmental factors, resulting in a lower germination rate in the natural state, and the germination rate of fresh fruits only reaches 25%, which is also not conducive to the needs of quickly obtaining seedlings in production. Seed initiation is based on the nature of the seeds and the water absorption rate before sowing, by controlling the slow water absorption of the seeds, ma...
