Celery seeds germinate in 7 to 10 days.

Celery seeds germinate in 7 to 10 days at the right temperature. The minimum temperature for germination of celery seeds is 4 degrees Celsius. The optimum temperature is 15 to 20 degrees Celsius. Also adequate moisture is necessary for seed germination. It needs moisture and does not tolerate dryness. A general moisture content of 70 to 80 percent is good. Also need enough oxygen.

Below 15 degrees Celsius, the seed germination time will be extended, 25 degrees Celsius and above the germination rate is significantly reduced, 30 degrees Celsius and above almost no germination. Below 30 degrees Celsius, the greater the temperature difference the higher the germination rate.

Celery seed germination method:

1, soak the seeds in water for 24 hours, so that the seeds fully absorb water. Then rub the seeds and wash them several times until the water is clear. The seeds will be spread on a straw mat in the shade to dry a little, dissipate excessive water on the surface of the seeds. After drying the seeds in a tile pot, covered with a damp cloth, placed in a cool ventilated place to germinate.

2, the seeds into a cloth bag, wet with min water and hang into the well, about 30 cm from the water surface, so that it is in a low-temperature, humid environment to absorb water and expand. 24 hours later, take back to put Xuan in 15 ~ 20 ℃ germination, the temperature should not be too high, in order to prevent the germination of the Senkan Dongqi or caused by the root of the embryo is slender. Rinse with water 2 to 3 times a day, 2 to 3 days hand 80% of the embryonic roots can be exposed to seed.

3, the soaked seeds, refrigerated at a low temperature of 0 ~ 1 ℃ for 3 days, and then placed in 15 ~ 20 ℃ under the condition of germination, can shorten the germination time, improve the neatness of germination. Soaking seeds with 100 ppm of erythromycin or 1% thiourea can be used instead of low-temperature treatment to obtain the same effect.
