Embodiment 1

[0048] Embodiment 1 of the present invention: Pseudostellariae Radix Pseudostellariae seed chamber of the present invention removes dormancy and germination test method, is to realize by following steps:

[0049] Restoration of dormancy: wash the fine sand with a fineness of about 2mm, dry and sterilize it at 121°C for 23 minutes, and put it into a leaky container; soak the Pseudostellariae seeds in distilled water for 24 hours, put them in a canvas bag, and bury them above The bacteria-treated fine sand is buried at a depth of 6cm, and the container is placed in an environment of -2~3°C for 65 days to keep the fine sand moist.

[0050] Germination bed preparation: Clean and sterilize the petri dish with a diameter of 12 cm, and then spread fine sand of about 2 mm for drying and sterilization at 121 °C for 23 minutes on the bottom 0.5 cm of the petri dish; the fine sand in the petri dish is fully moistened with distilled water Wet, drain excess water.

Embodiment 2

[0052] Embodiment 2 of the present invention: The method for releasing dormancy and germination of Pseudostellariae seeds in the room of the present invention is realized through the following steps:

[0053] Restoration of dormancy: wash the fine sand with a fineness of about 1mm, dry and sterilize it at 120°C for 20 minutes, and put it into a leaky container; soak the Pseudostellariae seeds in distilled water for 20 hours, put them in a canvas bag, bury them and sterilize them above. The bacteria-treated fine sand should be buried at a depth of 5cm, and the container should be placed in an environment of -2~3°C for 35 days to keep the fine sand moist.

[0054] Preparation of the germination bed: Clean and sterilize a 12cm diameter petri dish, and then spread 3 layers of filter paper on the bottom of the petri dish; the filter paper in the petri dish is fully wetted with distilled water, and the excess water is drained off.

Embodiment 3

[0056] Embodiment 3 of the present invention: The method for releasing dormancy and germination of Pseudostellariae seeds in the room of the present invention is realized through the following steps:

[0057] Restoration of dormancy: wash the fine sand with a fineness of about 3mm, dry and sterilize it at 122°C for 25 minutes, and put it into a leaky container; soak the seeds of Pseudostellariae Pseudostellaria in distilled water for 26 hours, put them in a canvas bag, and bury them above In the bacterium-treated fine sand, the buried depth is 8cm, and the container is placed in an environment of -2~3°C for 70 days to keep the fine sand moist.

[0058] Preparation of the germination bed: Clean and sterilize a petri dish with a diameter of 12 cm, and then spread 3 layers of gauze on the bottom of the petri dish; the gauze in the petri dish is fully moistened with distilled water, and the excess water is drained.

Abstract

The invention discloses methods for rapidly breaking a dormant state of seeds of heterophylly falsestarwort root and performing germination test. The method for rapidly breaking the dormant state of the seeds of the heterophylly falsestarwort root comprises the following steps of: cleaning fine sand with the fineness of 1 to 3mm, drying and sterilizing at the temperature of 120 to 122 DEG C for 20 to 25min, and loading into a water leakage container; soaking the seeds of the heterophylly falsestarwort root in distilled water at normal temperature for 20 to 26h, loading into a canvas bag, and burying in the fine sand, wherein the buried depth is 5 to 8cm; and placing the container in an environment at the temperature of -2 to 3 DEG C, and stratifying for 35 to 70 days. By controlling stratification time, germination temperature and illumination, the germination rate of the seeds of the heterophylly falsestarwort root reaches over 85 percent; and the methods are easy to operate, the accuracy of the germination test is high, the improvement of the growth rate, vigorous rate and regular rate of plants is facilitated, the seedling cultivation period is effectively shortened, the seedling cultivation cost is reduced, and the problems of long dormant period and difficult germination test of the seeds of the heterophylly falsestarwort root are radically solved.

Description

technical field [0001] The invention relates to a method for quickly releasing the dormant state of heterophylla heterophylla seeds and testing for germination, and belongs to the technical field of medicinal material cultivation. Background technique [0002] Pseudostellaria, also known as children's ginseng, four-leaf ginseng, and rice ginseng, is a plant of the genus Pseudomonas ginseng. Wild Pseudostellaria is distributed in Liaoning, Hebei, Shandong, Anhui, Jiangsu and other provinces. Its root tubers have the effects of nourishing qi and invigorating the spleen, promoting body fluid and moistening the lungs, and have broad application prospects in the treatment of common and frequently-occurring diseases such as cardiovascular and cerebrovascular diseases, diabetes, liver diseases, gastrointestinal diseases and tumors. In recent years, with the research and development of health food and cosmetics, the demand for Pseudostellaria heterophylla has increased sharply, and...
