Problems solved by technology

[0004] After searching, we only found reports about using phytohormones to treat the seeds of Notopterygium broadleaf, but there are problems such as low germination rate and unstable results.
Up to now, there is still no report about the success of notopterygia seed treatment to obtain a high germination rate stably

Embodiment 1

[0036] A method for breaking sleep and germination of notopterygium seeds, characterized in that it comprises the following steps:

[0037] A. Selection

[0038] Wild notopterygium seeds harvested in September 2003 in Ganzi County, Sichuan Province, which were ripe in the same year, with uncracked fruit and green skin, removed impurities and shriveled seeds. The seed purity was 95.5%, the thousand-grain weight was 3.49g, and the vitality was 91.50%.

[0039] B. Seed soaking

[0040] Soak the notopterygium seeds screened in step A with water at 20°C for 12 hours until saturated;

[0041] C. Sand storage variable temperature stratification and seed dormancy

[0042] First wash the river sand to remove the soil, dry it at 130°C for 2 hours, then cool it down to room temperature naturally, then mix the notopterygium seeds treated in step B with the river sand at a ratio of 1:3, and then carry out stage-variable temperature stratification:

[0043] The first stage: 50 days of st...

Embodiment 2

[0050] A method for breaking sleep and germination of notopterygium seeds, characterized in that it comprises the following steps:

[0051] A. Selection

[0052] Wild notopterygium seeds harvested in September 2003 in Ganzi County, Sichuan Province, which were ripe in the same year, with uncracked fruit and green skin, removed impurities and shriveled seeds. The seed purity was 95.5%, the thousand-grain weight was 3.49g, and the vitality was 91.50%.

[0053] B. Seed soaking

[0054] Soak the notopterygium seeds screened in step A with water at 20°C for 12 hours until saturated;

[0055] C. Sand storage variable temperature stratification and seed dormancy

[0056] First wash the river sand to remove the soil, dry it at 130°C for 2 hours, then cool it down to room temperature naturally, then mix the notopterygium seeds treated in step B with the river sand at a ratio of 1:2, and then perform step-by-step temperature-variable stratification:

[0057] The first stage: Stratified...

Embodiment 3

[0064] A method for breaking sleep and germination of notopterygium seeds, characterized in that it comprises the following steps:

[0065] A. Selection

[0066] Mature wild notopterygium seeds collected from Ganzi County, Ganzi Prefecture, Sichuan Province in October 2002 and stored in a dry environment at 0-5°C for one year were selected to remove impurities and shriveled seeds. The purity of the seeds was 98%, and the thousand-grain weight was 3.10g. Force 76.75%;

[0067] B. Seed soaking

[0068] Soak the notopterygium seeds screened in step A with water at 30°C for 12 hours until saturated;

[0069] C. Sand storage variable temperature stratification and seed dormancy

[0070] First wash the river sand to remove the soil, dry it at 130°C for 2 hours, then cool it down to room temperature naturally, then mix the notopterygium seeds treated in step B with the river sand at a ratio of 1:2, and then perform step-by-step temperature-variable stratification:

Abstract

A dormancy waking up and germinating method for the seeds of notopterygium includes properly changing the temp to wake up said seeds in dormanant state, promoting the germination of said seeds, and controlling the temp, culture medium and sowing depth to obtain high-quality seedlings.

Description

technical field [0001] The invention relates to a method for relieving the dormancy period of seeds of plateau medicinal materials and promoting seed germination. Specifically, the invention relates to a method for breaking dormancy of notopterygium seeds and promoting germination, germination and emergence of notopterygium seeds. Background technique [0002] Notopterygium incisum Ting ex H.T.Chang is a perennial herbaceous plant of the genus Notopterygium in the Umbelliferae family unique to my country. It is the same genus of notopterygium N.forbesii Boiss. One of the commonly used medicinal materials of Tibetan and Qiang medicine, it is mainly distributed in the alpine mountainous areas of Sichuan, Qinghai, Gansu, Tibet and other provinces, and has always relied on wild digging. Predatory mining and habitat destruction in recent years have caused resource depletion and loss of seed resources in various production areas. It has been listed as a national Class III protected...
