Herbs have a wide variety of seed varieties, there is no specific detection methods, each species has a difference.

But the company through years of laboratory testing experience, roughly differentiated in two large areas. Ie perennial perennial varieties and annual dwarf varieties of physiological dormancy, physical dormancy. Of course, from the light and the light can also be classified.
01. Physiological dormancy: mainly manifested in the seed itself or the maturity is not enough to lead to the current low bud rate.

Perennial varieties of seeds are mostly physiological dormancy, that is to say after the ripe, such as blue flower flax, white cucumber, snake chrysanthemum, torch flowers and other harvested seeds if not treated, the germination rate of only 20 %about. Before seeding rate, observe the seed color to determine the date of production of the seed, if the new seed, the need for temperature refrigeration and its layer treatment. In the ordinary light incubator it is difficult to make an accurate bud rate. Individual varieties of raw bean sprouts in rural areas is very effective way to wash the seeds (rinse once a day to ensure that the seed surface does not produce mold), the water temperature remained at 32 degrees. If the variety is small, you can use a clean wet towel wrapped in seeds after the placement of the petri dish or plastic wrap (to prevent water loss, towel humidity is squeezed by hand dripping, and not natural drip is appropriate), and then placed in the incubator temperature treatment. Normal germination ends in 3-15 days. Remember to record the germination rate in winter in a large temperature difference. Excessive temperature difference will lead to seed germination and loss of germination ability.
