Problems solved by technology

Most of the cultivated varieties are white-stemmed celery introduced from Japan, but the seed cost is too high when introduced from Japan; the production cost is too high and it is not conducive to the research of new varieties by using tissue culture technology
Relevant studies have shown that there is a deep dormancy phenomenon in the seeds of celery, and the germination rate of the seeds without any treatment is extremely low, almost zero

Embodiment 1

[0017] Embodiment 1, gather duck celery seed. To collect mature celery seeds in the wild or in the field, the seed coat is required to be complete, plump, and yellow or brownish-yellow in color. Since the inflorescence of celery is an infinite inflorescence, the seeds mature gradually from bottom to top along the axis of the inflorescence, so it is necessary to cover the entire axis of the inflorescence with a cloth bag or a collection bag, then pick the mature seeds, and collect the immature parts after 3 to 5 days. Put the collected celery seeds into the collection bag and seal it well, and store it in the dark at room temperature for later use.

[0018] Test germination rate:

[0019] (1) Determination of initial germination rate; select seeds with similar size and maturity, place them in a petri dish (Φ9cm) with double-layer filter paper inside, 30 seeds per dish, repeat in 3 groups, keep the filter paper moist, and place them in a light incubator Cultivate at a constant...

Abstract

The invention discloses a wild cryptotaenia japonica seed dormancy breaking method and relates to the field of biological technology application. Particularly, a mode of combining a measure of soaking seeds for 36 hours by clean water and a measure of carrying out cold storage on the seeds at a low temperature being 5 DEG C for 30 days is adopted, the dormancy of the cryptotaenia japonica seeds is broken, and in addition, the germination rate reaches a value higher than 95 percent. The method solves the problem of cryptotaenia japonica seed germination difficulty, the method is simple and is easy to implement, the cost is low, chemical pollution is avoided, and the technical support is provided for the wild cryptotaenia japonica industrial production and the ordinary farmer culture.

Description

technical field [0001] The present invention relates to a field of biotechnology applications. Specifically, a method that is simple, easy to implement, low in cost and free from chemical pollution is used to break the dormancy of wild vegetable celery seeds and solve the problem of difficult germination of celery seeds. The industrial production of duck celery and the planting of general farmers provide technical support. Background technique [0002] Cryphtotaenia japonica Hassk, also known as Cryphtotaenia japonica Hassk, is a perennial herb of the genus Cryphtotaenia in the Umbelliferae family. It is produced in Hebei, Anhui, Jiangsu, Zhejiang, Fujian, Jiangxi, Guangdong, Guangxi, Hubei, Hunan, Shanxi, Shaanxi, Gansu, Sichuan, Guizhou, Yunnan, Korea, and Japan. It likes to grow in damp places under forests. It has a wide range of uses, the whole plant and root can extract aromatic oil; the fruit can be squeezed oil for making soap and paint; the whole plant and fruit ca...
