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...

Examples

Embodiment 1

[0014] (1) Remove the outer testa: choose to harvest the seeds when the fruit of Chonglou is ripe and the peel is cracked, mix the fresh seeds of Chonglou with wet sand, and remove the red and juicy outer testa of Chonglou seeds in time by rubbing each other , and rinse with clean water;

[0015] (2) Hydrogen peroxide treatment: after removing the outer testa of the seeds of the pachyrhiza seeds with filter paper, soak them in 2% hydrogen peroxide for 8 hours, and the whole soaking process is carried out under shading conditions at 4°C;

[0016] (3) Gibberellin treatment: After the hydrogen peroxide-treated seeds of P. edulis were first blotted with filter paper to dry the surface moisture, then placed at 20°C for 18 hours to dry, and then put the dried seeds into 300mg / L gibberellin Soak in the solution for 36 hours, and the soaking process is carried out under shading conditions at 20°C;

[0017] (4) Germination culture: take out the seeds soaked in the gibberellin solution...

Embodiment 2

[0019] The concentration of the hydrogen peroxide solution in the embodiment 1 step (2) is changed into 1%, and other steps are the same as in the embodiment 1, and the seeds of Chonglou grow radicles after cultivating for 5 months and start to germinate.

Embodiment 3

[0021] Change the concentration of gibberellin solution into 400mg / L in the embodiment 1 step (3), and other steps are with embodiment 1, and the radicle of the chrysanthemum seed grows after cultivating 4 months, and begins to germinate.
