Embodiment 1

[0015] 1. Take 50 Jerusalem artichoke seeds at random, and treat the Jerusalem artichoke seeds with inhibited germination and fever for 2 days under the temperature condition of 7℃ and alternate light conditions to restore the germination of the Jerusalem artichoke seeds with inhibited germination and fever. The alternate lighting conditions are: 14 hours of light per day and 10 hours of darkness ; Place the treated Jerusalem artichoke seeds on a rooting medium with 1 / 2MS as a basic medium, containing 30 mg / L of sucrose, 7 mg / L of agar, 0.1 mg / L of NAA, and a pH of 5.6; the intensity of light is specifically 1500 Lux.

[0016] 2. When the test tube shoots grow to 2cm, they can be directly cut and transferred to the rooting medium for rooting culture, without strong seedling culture. When the roots grow to 3cm, they can be cultivated and then transplanted to the field.

[0017] 3. The specific steps of refining seedlings are as follows: Loosen the cap of the test tube, 2 days; Add ...

Embodiment 2

[0019] 1. Take 50 Helianthus tuberosus seeds at random, and treat the Helianthus tuberosus seeds with inhibited germination and fever for 5 days under the temperature condition of 21℃ and alternate light conditions to restore the germination of Helianthus tuberosus seeds with inhibited germination and fever. The alternate lighting conditions are: daily light for 12 hours and dark for 12 hours ; Place the treated Jerusalem artichoke seeds on a rooting medium with 1 / 2MS as a basic medium, containing 30 mg / L of sucrose, 7 mg / L of agar, 0.1 mg / L of NAA, and a pH of 5.7; the intensity of light is specifically 1800 Lux.

[0020] 2. When the test tube seedling shoot grows to 3cm, it can be directly cut and transferred to the rooting medium for rooting culture without strong seedling culture. When the root grows to 4cm, it can be cultivated by tempering seedlings, and finally transplanted to field cultivation.

[0021] 3. The specific steps of refining seedlings are as follows: Loosen the ...

Embodiment 3

[0023] 1. Take 50 Helianthus tuberosus seeds at random, and treat the Helianthus tuberosus seeds with inhibited germination and fever for 3 days under the temperature condition of 15℃ and alternate light conditions to restore the germination of Helianthus tuberosus seeds with inhibited germination and fever. The alternate lighting conditions are: 13 hours of light per day and 11 hours of darkness ; Place the treated Jerusalem artichoke seeds on a rooting medium with 1 / 2MS as a basic medium, containing 30 mg / L of sucrose, 7 mg / L of agar, 0.1 mg / L of NAA, and a pH of 5.6; the intensity of light is specifically 1700 Lux.

[0024] 2. When the test tube shoots grow to 2cm, they can be directly cut off and transferred to the rooting medium for rooting culture, without strong seedling culture. When the roots grow to 4cm, they can be refined and transplanted to the field.

[0025] 3. The specific steps of refining treatment are as follows: Loosen the cap of the test tube, 2 days; Add ster...

Abstract

The invention discloses a method for seed germination of jerusalem artichoke, and relates to a recovery method of heat suppression of seed germination, belonging to the technical field of agriculture. The method is characterized by processing the jerusalem artichoke seeds subjected to germination heat suppression for 2-5 days under the temperature condition of 7-21 DEG C and alternative light to enable the ierusalem artichoke seeds subjected to germination heat suppression to recover the germination, wherein the alternative light condition is as follows: the lighting time is 12-14 hours each day, the dark time is 10-12 hours; placing the processed jerusalem artichoke seeds in a rooting culture medium which uses 1 / 2MS as the basic culture medium, wherein the culture medium contains 30mg / L of sucrose, 7mg / L of agar and 0.1mg / L of NAA (1-Naphthaleneacetic Acid), and the pH is 5.6-5.7. The method disclosed by the invention has the benefit effects that the recovered seed germination of the jerusalem artichoke approaches to or achieves 100%, the seed germination, especially the heat suppression problem of the seed germination in the industrialized seedling in the production of the jerusalem artichoke is solved; and the seedling production rate of the recovered seed is more than 94% under the temperature-changing and alternative lighting condition.

Description

Technical field [0001] The invention relates to a method for restoring seed germination and heating inhibition, belonging to the technical field of agriculture, and specifically to a method for germination of Jerusalem artichoke seeds. Background technique [0002] Jerusalem artichoke ( Jerusalem artichoko ), common name Jerusalem artichoke, Dihuan, Ginger is not spicy, Compositae, Helianthus, perennial herb. The edible part is generally tuber, with fusiform or irregular tumor type; the skin is red, yellow and white; the texture is fine and crisp, but the quality of fresh food is not good. Jerusalem artichoke tubers are storage-resistant, rich in amino acids, sugars, vitamins, etc. Each 100g of tubers contains 79.8g of water, 0.1g of crude protein, 0.1g of fat, 16.6g of carbohydrates, 0.6g of crude fiber, 2.8g of ash, 49mg of calcium, and phosphorus. 119mg, iron 8.4mg, vitamin B 10.13mg, vitamin B 20.06mg, niacin 0.6mg, vitamin C 6mg, and rich in inulin, pentose, starch and ot...
