Embodiment 1

[0017] A method for breaking dormancy of columbine seeds, the method comprising the following steps:

[0018] (1) Seed collection: select robust plants without damage by diseases and insect pests, cut off the whole inflorescence with scissors and dry it in the sun when the seeds are fully mature, and screen out plump and fully mature seeds for subsequent use;

[0019] (2) Soak the columbine seeds in a potassium dihydrogen phosphate solution with a temperature concentration of 50 g / L for 15 hours, then soak them in thiophanate-methyl 800 times solution for 2.5 hours, and finally wash the seeds with warm water at about 28°C;

[0020] (3) Preparation of plant extract: select well-developed plants, collect roots, stems, and leaves of vetiver, cut them into pieces with scissors after drying in the shade, weigh 2, 10, and 4 g of roots, stems, and leaves respectively, and add 100 times Distilled water, soaked at 25°C for 48 hours, filtered through 4 layers of gauze to obtain the stoc...

Embodiment 2

[0023] A method for breaking dormancy of columbine seeds, characterized in that the method comprises the following steps:

[0024] (1) Seed collection: select robust plants without damage by diseases and insect pests, cut off the whole inflorescence with scissors and dry it in the sun when the seeds are fully mature, and screen out plump and fully mature seeds for subsequent use;

[0025] (2) Soak the columbine seeds in a potassium dihydrogen phosphate solution with a temperature concentration of 60g / L for 18 hours, then soak them in 800 times thiophanate-methyl solution for 2.5 hours, and finally wash the seeds with warm water at about 28°C;

[0026] (3) Preparation of plant extract: select well-developed plants, collect roots, stems, and leaves of vetiver, cut them into pieces with scissors after drying in the shade, weigh 2, 10, and 4 g of roots, stems, and leaves respectively, and add 100 times Distilled water, soaked at 30°C for 48 hours, filtered through 4 layers of gauz...

Abstract

The invention relates to a method for breaking dormancy of aquilegia viridiflora seeds. The method mainly comprises the following steps: selecting seeds, immersing seeds, immersing by plant extract, and carrying out stratification. According to the method, the germination time of aquilegia viridiflora seeds can be greatly shortened by comprehensively utilizing immersing, stratification and other technologies for breaking dormancy of seeds; and the seed seedling of aquilegia viridiflora prepared by utilizing the method has the advantages of strong root system, good growth vigor, high growth speed and high survival rate.

Description

technical field [0001] The invention relates to a method for breaking the dormancy of columbine seeds. Background technique [0002] Aquilegia, alias: cat's claw flower, Latin scientific name: Aquilegia viridiflora Pall., is a species of Ranunculaceae and the genus Aquilegia. Native to Europe and North America. It is a perennial herbaceous plant with a large root, cylindrical shape, up to 1.5cm in diameter, simple or a few branches, and dark brown outer skin. Leaves come out of the root, the surface of the leaf is shiny, and there are hairs on the back. It blooms in June and July, usually dark blue-purple or white, with yellow anthers, for medicinal purposes. Born in mountain roadsides, riversides or wet grasslands at an altitude of 200-2300m. Distributed in Northeast China, North China and Shaanxi, Ningxia, Gansu, Qinghai and other places. Distributed in the Russian Far East. It has good ornamental value and can also be used as medicine. [0003] There is no report ab...
