Problems solved by technology

Abutilon seeds mature and fall off from September to October, germinate from February to March of the following year, and have a dormant period of 5 to 6 months. Under natural conditions, the emergence rate is low, so the utilization rate of Abutilon seeds is low in production.
In the existing literature, light, temperature, different pH and different warm soups are used to treat the seeds of Abutilon. Although the four methods are effective, the highest seed germination rate of Abutilon can only be increased to 61.45%. And there is only research on the germination index of seeds, but no research on fresh weight, seedling height and root length. Therefore, solving the hard and dormant seeds of Abutilon and promoting its germination is of great significance to the cultivation, utilization and breeding of Abutilon

Embodiment 1

[0018] A method for promoting germination of Abutilon seeds, comprising the following steps:

[0019] Step 1: Take mature Abutilon seeds and store them at 4°C for 1-2 weeks;

[0020] Step 2: Take the Abutilon seeds stored in Step 1, place them in 60°C water, stir them, and soak them for 30 minutes. After soaking, take out the seeds and dry them in the air;

[0021] Step 3: prepare 40mmol / L calcium chloride solution, take the dried velvetleum seeds of step 2, place them in the prepared calcium chloride solution and soak the seeds for 12 hours, then rinse with water and use 1% sodium hypochlorite to seed disinfect;

[0022] Step 4: Take the velvetleum seeds sterilized in step 3, and cultivate them in a constant temperature light box at 20°C, alternating light and dark for 12 / 12 hours, and ventilate for at least 5 minutes every day, and the seeds will germinate in 4 to 8 days.

Embodiment 2

[0024] A method for promoting germination of Abutilon seeds, comprising the following steps:

[0025] Step 1: Take mature Abutilon seeds and store them at 4°C for 1-2 weeks;

[0026] Step 2: Take the Abutilon seeds stored in Step 1, place them in 45°C water for stirring, soak the seeds for 60 minutes, and take out the seeds after soaking and dry them in the air;

[0027] Step 3: prepare 20mmol / L calcium chloride solution, take the dried velvetleum seeds in step 2, place them in the prepared calcium chloride solution and soak the seeds for 12 hours, then rinse with water and use 1% sodium hypochlorite to treat the seeds disinfect;

[0028] Step 4: Take the velvetleum seeds sterilized in step 3, and cultivate them in a constant temperature light box at 20°C, alternating light and dark for 12 / 12 hours, and ventilate for at least 5 minutes every day, and the seeds will germinate in 4 to 8 days.

Embodiment 3

[0030] A method for promoting germination of Abutilon seeds, comprising the following steps:

[0031] Step 1: Take mature Abutilon seeds and store them at 4°C for 1-2 weeks;

[0032] Step 2: Take the Abutilon seeds stored in Step 1, place them in 65°C water for stirring, soak the seeds for 15 minutes, take out the seeds after soaking and dry them in the air;

[0033] Step 3: prepare 60mmol / L calcium chloride solution, take the dried velvetleum seeds of step 2, place them in the prepared calcium chloride solution and soak the seeds for 12h, then rinse with water and use 1% sodium hypochlorite to seed disinfect;

[0034] Step 4: Take the velvetleum seeds sterilized in step 3, and cultivate them in a constant temperature light box at 20°C, alternating light and dark for 12 / 12 hours, and ventilate for at least 5 minutes every day, and the seeds will germinate in 4 to 8 days.

Abstract

The invention relates to a method for promoting germination of seeds and specifically relates to a method for promoting germination of abutilon theophrasti seeds. The abutilon theophrasti seeds are treated by use of different seed soaking methods, so that the problem of low germination rate due to hard abutilon theophrasti seeds and the like can be solved and the germination rate of the abutilon theophrasti seeds can be rapidly increased in short time; besides, the method is capable of increasing the germination potential, the fresh weight, the seedling height and the root length, speeding up the germination of the abutilon theophrasti seeds and promoting strong seedling, and is significant for increasing the propagation coefficient of abutilon theophrasti, protecting resources and improving the efficiency of artificial cultivation.

Description

technical field [0001] The invention relates to a method for promoting germination of seeds, in particular to a method for promoting germination of Abutilon seeds. Background technique [0002] Abutilon ( Abutilon theophrasti Medic) belongs to Malvaceae. Abutilon is an annual subshrub-like herbaceous plant with a height of 1~2m. Its whole plant and roots can be used as medicine. Otitis media, sore joints; it has the effect of clearing away heat and dampness, detoxification and removing nebula. For a long time, the sources of medicinal materials of Abutilon almost mainly depend on wild plant resources. Due to the development of the economy and industry, the land area is decreasing day by day, and the wild resources of Abutilon are getting more and more destroyed and shrinking day by day. The market supply of Abutilon has become an urgent problem to be solved now. The seed coat of Abutilon seeds is hard and dormant, and the germination rate is very low in the natural s...
