Embodiment 1

[0024] Aging seeds of oats with germination rates of 52% and 70% were selected as the test materials, denoted as G52 and G70, respectively. See Table 1 for specific germination conditions.

[0025] Table 1: Germination status of tested oat aging seeds

[0026]

[0027] Refer to Chapter 9 of the International Seed Inspection Association (ISTA, 2015) Seed Inspection Regulations to determine the initial moisture content of oat seeds. According to the initial moisture content of the oat seeds, the weight of the oat seeds when the moisture content is 10% is calculated. Using the saturated salt solution balance static weighing method, the oat seeds are balanced in a closed container containing a saturated NaBr solution (balanced relative humidity of 57%), and the weight of the oat seeds is weighed until the oat seeds reach the required weight.

[0028] Aging seeds of oats were treated with 0μM, 1μM, 10μM, 100μM, 200μM, 500μM and 1000μM melatonin solution (denoted as C, M1, M10, M100, M200...

Embodiment 2

[0067] Two aged oat seeds with different germination levels of 52% and 70% were selected as the test materials, denoted as G52 and G70 respectively.

[0068] Refer to Chapter 9 of the International Seed Inspection Association (ISTA, 2015) Seed Inspection Regulations to determine the initial moisture content of oat seeds. According to the initial moisture content of the oat seeds, the weight of the oat seeds when the moisture content is 10% is calculated. Using the saturated salt solution balance static weighing method, the oat seeds are balanced in a closed container containing a saturated NaBr solution (balanced relative humidity of 57%), and the weight of the oat seeds is weighed until the oat seeds reach the required weight.

[0069] Oat seeds were treated with 0μM, 1μM, 10μM, 100μM, 200μM, 500μM, and 1000μM melatonin solutions (denoted as C, M1, M10, M100, M200, M500, M1000), and ignited for 12h at 20℃ in the dark. 24h and 36h (denoted as T12, T24, T36), change the solution ev...

Abstract

The invention belongs to the technical field of seed vigor improvement and seed germination promotion, and discloses a method for promoting germination of oat aged seeds and growth of seedlings. The method comprises the following steps: firstly, determining the initial water content of the oat aged seeds to be tested, and after adjusting the water content, soaking the oat aged seeds for 24-36 hours by using a melatonin solution with the concentration of 1 (mu) M-1,000 (mu) M, then taking out the oat aged seeds to be tested and washing with distilled water; and finally, drying until the water content of the oat aged seeds to be tested is equal to the initial water content. In an existing seed priming technology, priming time and concentrate of a priming agent are affected by kinds of seeds and initial quality of the seeds and are not determined, specific parameters of the oat aged seeds primed by melatonin are determined by research, improvement and application of a technology of priming and treating the oat aged seeds by using the melatonin are realized, and the standard operation method for promoting germination of the oat aged seeds and improving vigor of the aged seeds is provided.

Description

Technical field [0001] The invention belongs to the technical field of improving seed vigor and promoting seed germination, and specifically relates to a method for promoting the germination and seedling growth of aged oat seeds by using melatonin. Background technique [0002] Oats (Avena sativa L.) is an annual forage plant of the genus Oats in the Gramineae family. As a high-quality forage for livestock and poultry, oat leaves and straws are green and juicy, have good palatability, high crude protein and fat content, and high nutritional value. They can be used to make green hay and silage. At the same time, oats' drought-resistant and adversity-resistant characteristics determine that they can adapt to the harsh environment in arid areas, increase the vegetation coverage in pastoral and semi-agricultural and pastoral areas, help reduce surface runoff, protect soil fertility, and play an important role in improving the ecological environment. . In addition, as a green nutrit...
