Problems solved by technology

In addition, when calcium peroxide dissolves in water, it will produce calcium hydroxide, which will make the solution alkaline and cannot be combined with acidic plant hormones or chemicals (the chemical structure of gibberellin belongs to diterpenoid acids, and salicylic acid is a lipid). Soluble acid, etc.) mixed use, resulting in calcium peroxide oxygenator has certain limitations, unfavorable promotion
[0005] Therefore, looking for a kind of oxygen enhancer that is better than calcium peroxide can avoid the problem that calcium peroxide cannot be mixed with conventional initiators such as gibberellin and salicylic acid while simplifying the initiation procedure and reducing costs. is a necessary research direction in the future

Embodiment 1

[0017] 1. Experimental content

[0018] 1. Materials

[0019] Honghuadajinyuan (Hongda) tobacco seeds were provided by the seed company of China Tobacco Yuxi Seed Co., Ltd. Gibberellin (GA 3 ), purchased from Sigma, USA, with a purity of 95%. 30%H 2 o 2 The solution was purchased from Sinopharm Chemical Reagent Company.

[0020] 2. Initiate the experiment

[0021] A total of 9 treatments. First, using 50mg / L of GA 3 The solution is the basic trigger solution, containing 0, 10, 25, 50, 100, 200mmol / L H 2 o 2 ; Utilize 50mg / L GA 3 Solution and pure water trigger, adopt mechanical ventilation; use 50mmol / L H 2 o 2 solution triggers. Tobacco seeds and triggering liquid are placed in a test tube at a ratio of 1:10 (g:ml), and sealed with a parafilm. After initiating at 30°C for 48 hours, quickly rinse the seeds with clean water, ventilate at room temperature and return to dry to the original moisture.

Embodiment 2

[0041] 1. Experimental content

[0042] 1. Materials

[0043] Meiyu 3 corn seeds. Salicylic acid (SA) was purchased from Sigma, USA, with a purity of 98%. 30%H 2 o 2 The solution was purchased from Sinopharm Chemical Reagent Company.

[0044] 2. Initiate the experiment

[0045] The 70mg / L SA solution was used as the basic trigger solution, containing 0, 10, 25, 50, 100, 200mmol / L H 2 o 2 . The ratio of corn seeds to trigger solution is 1:10 (g:ml) and placed in a beaker, sealed with a parafilm. After initiating at 20°C for 30 hours, the seeds were quickly rinsed with clean water, and ventilated at room temperature to return to the original moisture.

[0046] 3. Determination of dissolved oxygen content

[0047] When the initiation time is 0h, 2h, 6h, 12h, 18h, 24h, 30h, the dissolved oxygen in the initiation solution is measured by JPBJ-608 portable dissolved oxygen meter.

Abstract

The invention discloses a seed priming solution and method. The seed priming solution comprises a priming agent and an oxygenate, wherein the oxygenate is hydrogen peroxide. According to the seed priming solution, hydrogen peroxide is used as the oxygenate and is added into the seed priming solution for seed priming, and no additional priming and oxygenating devices and stirring work are needed, so that the priming operation procedure is greatly simplified. At the same time, hydrogen peroxide can be cooperated with the priming agent such as gibberellin or salicylic acid which is frequently used in the existing priming technology to promote seed germination, so that the seed priming effect is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of plant seed treatment, in particular to a seed priming solution and a seed priming method. Background technique [0002] Seed priming is one of the important methods to improve seed vigor. Seed priming is by controlling the slow water absorption of the seeds, allowing the seeds to pre-germinate, so that they are in a state of germination. Initiation can promote seed germination, improve germination uniformity, shorten emergence time, improve seedling quality and stress resistance, and has broad application prospects in production. Liquid priming involves soaking the seeds in a priming solution, and after a period of time, removing the seeds and returning them to their original moisture. Liquid priming is easy to operate and has obvious effects, and is one of the most commonly used priming methods at present. Gibberellins and salicylic acid are phytohormones that play an important role in regulating plan...
