Embodiment 1

[0010] The method to quickly release the dormancy of Sorbus rowan seeds is achieved by the following steps:

[0011] 1. Soak mature seeds of Sorbus tree in water at 20-35°C for 2 to 3 days to obtain swollen seeds. The water is added with 0.01-0.1% magnolol and 0.1-1% succinic acid;

[0012] 2. Stir and soak the swollen seeds with a sodium hypochlorite solution with a volume concentration of 1% to 3% for 10 to 15 minutes, then rinse with water for 3 to 5 times, and then peel off the seed coat to obtain a peeled seed;

[0013] 3. Place a filter paper fully soaked with pH 7.0 water in a 500ml beaker, and place 50-100 peeled seeds on it, and then place a 10-50ml small beaker in the 500ml beaker , The small beaker is filled with 5-10 ml of sodium nitroprusside solution with a concentration of 0.3-1.5 g / L, and then the mouth of the 500-ml beaker is sealed with plastic wrap, and the light intensity is 2000-3500 lux at 20-35℃ Place it for 2 to 5 hours under the conditions of, and then rinse...

specific Embodiment approach 2

[0020] Specific embodiment two: this embodiment is different from specific embodiment one in that in step one, the mature seeds of rowan are soaked in water at 25° C. for 2.5 days. Other steps and parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0021] Specific embodiment three: This embodiment is different from specific embodiment one in that in step two, the swollen seeds are immersed in a sodium hypochlorite solution with a volume concentration of 2% for 12 minutes, and then rinsed with water 4 times. Other steps and parameters are the same as in the first embodiment.

Abstract

The invention provides a method for quickly relieving mountain ash seed dormancy and relates to a method for quickly relieving seed dormancy. The method is used for solving the problems of long germinating time, low germination rate and irregular sprouting of a method for manually treating mountain ash seeds, and the problem of chemical toxics generated by a method for soaking seeds in a sodium nitroprusside solution at present. The method comprises the following steps: soaking and swelling mature mountain ash seeds; soaking and stirring the swelling seeds in a sodium hypochlorite solution; peeling the seeds, thereby acquiring the peeled seeds; treating the peeled seeds with the sodium nitroprusside solution; performing sprouting culture. According to the invention, the mountain ash seeds start to sprout on the third day of sprouting culture; on the eighth day of sprouting culture, the accumulated germination rate can reach up to 90%, which is 1.5 times or above of the germination rate of peeled seeds untreated with the sodium nitroprusside solution. According to the invention, the peeled seeds are not in direct contact with the sodium nitroprusside solution, so that chemical toxics are not generated; the mountain ash seed dormancy is quickly relieved; the germination rate of the mountain ash seeds is increased; the germination evenness of the mountain ash seeds is increased.

Description

Technical field [0001] The invention relates to a method for quickly releasing seed dormancy. Background technique [0002] Seed dormancy refers to the phenomenon that live seeds cannot germinate under suitable germination conditions (temperature, moisture, oxygen, etc.). It is one of the important adaptive characteristics of plants. Seed dormancy is a heritable trait whose degree is regulated by the environment during seed development. According to the time of seed dormancy, it can be divided into primary dormancy (the dormancy phenomenon that is already present at harvest) and secondary dormancy (the seeds without original dormancy or released from dormancy due to high humidity, low oxygen, high carbon dioxide, low water potential or lack of light Dormancy induced by the influence of unsuitable environmental conditions). The reasons for seed dormancy can be classified into two categories: The first category is caused by the embryo itself, including incomplete embryo developm...
