What are the three ways to accelerate seed germination?

Germination at low temperature, soaking, paper towel.

Accelerating germination is a measure that can cause bud growth, dormant bud development and seed germination, or promote these early occurrences, all of which are called accelerating germination. According to different conditions of seed growth and development, appropriate temperature, oxygen and air humidity will promote seed germination. Summarizing the measures of accelerating germination can cause the growth of buds, the development of dormant buds and the germination of seeds, or promote these before, which is called accelerating germination.

Accelerating germination is an important measure to ensure that the nutrients in the seeds are quickly decomposed and transported after the seeds absorb enough water to supply the growth of young embryos. According to different conditions of seed growth and development, appropriate temperature, oxygen and air humidity will promote seed germination. In agriculture, in addition to promoting germination (sweet potato, potato, etc. ), more refers to improving the germination rate of seeds or promoting orderly germination.

It is effective to treat dormant buds of trees (cloves) at low temperature, stimulate buds with water, acupuncture, peeling scales, and treating them with cigarettes, acetylene, ether, hydrogen and warm soup. The effect of treatment often varies with seasons, and most of them are effective from 65438+February to 65438+1October. Breaking the dormancy of perennial roots, bulbs and tubers can be treated with low temperature, dichloroethanol, clofenuron, clofenuron and gibberellin, or placed in a gas containing about half of CO2 for several days, or treated with high temperature (about 40℃) and sulfuric acid (sweet potato tuber) is often effective. General humidity and temperature, etc.

Suitable conditions are necessary for seed germination, but temperature treatment is also effective for hard-skinned seeds. Especially the seeds of alpine plants need low temperature treatment of about 0℃. Seeds that need light to germinate can germinate well under light.
