Seed treatment method for improving germination rate of hemerocallis fulva

Abstract

The invention discloses a seed treatment method for improving the germination rate of hemerocallis fulva. The method comprises the following steps: S1, cleaning: scrubbing the surfaces of seeds in clear water to be clean, and removing the seeds floating on the water surface; S2, soaking: taking a clean beaker containing distilled water, adding gibberellin into the beaker according to the amount of 2-3g/L of distilled water, uniformly stirring and mixing, then putting the seeds cleaned in the S1 into the beaker, and soaking for 12-24 hours at 4 DEG C; S3, peeling: taking out the seeds soaked in the step S2, and peeling off soaked and softened seed coats; S4, sowing the seeds; and S5, culturing, namely putting plug cells after sowing in the S4 on a matched non-porous tray, and wholly placing the plug cells in an environment of 25-28 DEG C for culturing. According to the method disclosed by the invention, the seed coats are stripped for direct sowing by utilizing the characteristic that the gibberellin breaks the dormancy of the seeds, so that the seed coat obstacle is broken, and the seed germination can be efficiently promoted. The treatment method is simple and easy to operate, the germination rate of the seeds can be remarkably increased, the dormancy breaking time is greatly shortened, and the seedling raising and breeding efficiency of the hemerocallis fulva seeds is improved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a seed treatment method for improving the germination rate of Hemerocallis. Background technique [0002] Hemerocallis (scientific name: Hemerocallis) is a perennial herb with short rhizomes and thick spindle-shaped fleshy roots. Hemerocallis has many aliases, including "golden needle", "day lily", and "forgetful grass". Among them, "day lily" is mostly eaten and has become a delicacy on the daily dining table of ordinary people. Not only that, day lily also has the effects of clearing away heat and diuresis, cooling blood and stopping bleeding, so it can be used medicinally. Hemerocallis is native to China, Siberia, Japan, and Southeast Asia. Although it is native to China, there is little improvement. Hemerocallis only reproduces by seeding, and the reproduction rate is far from enough. There are problems such as low seed germination rate, weak germination potential...

Problems solved by technology

Hemerocallis is native to China, Siberia, Japan and Southeast Asia. Although it is native to China, there is little improvement. Hemerocallis only reproduces by seeding, and the reproduction rate is far from enough

There are problems such as low seed germination rate, weak germination potential, long time-consuming, and low seedling growth efficiency in the existing dormancy-breaking technology and breeding seedlings
