Method for effectively breaking dormancy of Paris polyphylla seeds

Abstract

The invention discloses a method for effectively breaking the dormancy of Paris polyphylla seeds. By adopting a treatment way of combining hydrogen peroxide and the Gibberellins solution with suitable concentrations, the dormancy of the Paris polyphylla seeds is effectively broken, the after ripening period of the seeds is shortened, the germination time of about 2 years for the Paris polyphylla seeds in natural conditions is shortened to about 3 months, and the cultivation time of the Paris polyphylla seeds is greatly shortened.

Description

technical field [0001] The invention relates to a method for effectively relieving the dormancy of the seeds of P. edulis. Background technique [0002] The plant of Chonglou belongs to the genus Chonglou of Liliaceae, and it is the main raw material of many kinds of Chinese patent medicines such as Yunnan Baiyao, Gongxuening, Reduqing and so on. With the continuous expansion of its use, the demand for heavy building resources has also increased rapidly. According to statistics, at present, nearly 80% of the available heavy building resources have been developed, and the remaining 20% ​​resources may last for 3 to 5 years according to the current international and domestic demand analysis. Therefore, it is of great significance to carry out the cultivation of the medicinal plants of Pachyphylla polyphylla on a large scale. [0003] At present, the main problem restricting the large-scale planting and production of P. polyphylla is the shortage of P. polyphylla seedlings; b...

Problems solved by technology

[0004] At present, someone has applied for a patent on the technology of breaking the dormancy of the seeds of Chonglou. For example, the patent application document with the patent application No. Soak in 20-80ppm gibberellin, and then alternately culture at 4°C and 22°C, and add hormones and dianthus oligosaccharin to the medium at the same time, so that the seeds can germinate as early as 2 months. This technology Although it can effectively break the dormancy period of the seeds and shorten the germination time of the seeds, the temperature-changing operation process is complicated, and at the end it needs to be inserted into the medium containing hormones and oligosaccharidins, and the production cost is high.
