Method for breaking dormancy of thesium chinense seeds

Abstract

The invention relates to the technical field of thesium chinense planting, in particular to a method for breaking dormancy of thesium chinense seeds which comprises the following steps: soaking collected thesium chinense seeds in water, taking submerged thesium chinense seeds, air-drying the thesium chinense seeds, and storing the thesium chinense seeds at 2-4 DEG C to obtain standby thesium chinense seeds; soaking the standby thesium chinense seeds in a gibberellin solution, then taking out the seeds, mixing the seeds with river sand, and carrying out first stratification treatment under the condition of -4 DEG C to -2 DEG C; cleaning river sand, removing green peels and fruit stems of the thesium chinense seeds subjected to the first stratification treatment, performing moisturizing treatment, and then performing second stratification treatment under the condition of 2-4 DEG C to obtain hull-broken seeds; culturing three-slit-period shell-broken seeds serving as a germination material under a dark condition at 17-22 DEG C, and performing seed germination. The method can significantly improve the germination rate of the thesium chinense seeds, and has a good application prospect.

Description

technical field [0001] The application belongs to the field of thyme planting technology, in particular to a method for breaking the dormancy of thyme seeds. Background technique [0002] Thyme grass (Thesium chinense Turcz.) is a perennial semi-parasitic plant of the family Sandalaceae. Its dry whole herb is a commonly used Chinese herbal medicine in my country. Modern research shows that thyme has significant anti-inflammatory, analgesic and broad-spectrum antibacterial effects, known as "plant antibiotics". Clinically applied Bairuicao preparations mainly include Bairui Granules, Bairui Tablets, Bairui Capsules, etc. The functions and indications include clearing heat and reducing inflammation, relieving cough and reducing phlegm, and can be used to treat acute and chronic pharyngitis, bronchitis, rhinitis, cold, fever, Pneumonia and other symptoms. [0003] In recent years, due to reasons such as over-harvesting, environmental damage, and semi-parasitic biological char...

AI Technical Summary

Problems solved by technology

Predecessors can break the dormancy of thymegrass seeds through plant hormone treatment and variable temperature stratification, but the overall efficiency is low, the rate of breaking shells is low, the rate of germination is low, and the operability is poor.
