Abstract

A method for breaking dormancy of Thesium chinense Turcz. seeds, which includes: immersing collected seeds of Thesium chinense Turcz. in water, selecting seeds that sink in the water followed by air-drying, and storing at 2-4° C. to obtain to-be-used seeds; immersing the to-be-used seeds in a gibberellin solution, taking out the seeds and mixing with river sand under −4-2° C. for a first stratification treatment; rinsing off the river sand, removing green skins and stalks of the seeds after the first stratification treatment, keeping the seeds moist and placing the seeds under 2-4° C. for a second stratification treatment to obtain ruptured seeds; and using the ruptured seeds in a three-slit stage as a germination material, and culturing the ruptured seeds in a three-slit stage in a dark environment at 17-22° C. for seed germination. The method can significantly improve the germination rate of Thesium chinense Turcz. seeds.
