How to germinate celery seeds? Latest technical method tutorial
The sowing material of celery is the fruit, which has a thick and hard skin and oil glands, is difficult for water to penetrate, and germinates slowly and unevenly. Sowing in the high-temperature summer season is even more difficult. Therefore, before raising seedlings in summer and autumn or direct sowing, seed soaking and germination are required. Let us take a look at celery germination techniques below!
Soaking in clean water for germination
Soak the seeds in clean 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. Spread the seeds on a straw mat in a cool place to dry slightly, so that excess water on the seed surface is lost. Put the dried seeds in a clay pot, cover with a wet cloth, and place in a cool, ventilated place to germinate. The suitable temperature for germination is 15-20°C. During germination, turn the seeds once a day to make the temperature and humidity uniform, and wash the seeds with clean water 2 times every 2 days to prevent mildew. After washing, let them dry slightly, then continue germination. After about 7 days, when more than 80% of the seeds have sprouted white, they can be sown.
Soaking in well water for germination
Put the seeds into a cloth bag, moisten them with well water, and hang them into a water well at a distance of about 30 cm from the water surface, so that they absorb water and swell in a low-temperature and humid environment. After 24 hours, take them back and place them under 15-20°C conditions to germinate. The temperature must not be too high, to prevent uneven germination or thin radicles. Rinse with clean water 2-3 times a day. After 2-3 days, when 80% of the radicles are exposed, they can be sown.
Low-temperature treatment for germination
Refrigerate the soaked seeds at a low temperature of 0-1°C for 3 days, then place them under 15-20°C conditions to germinate. This can shorten the germination time and improve the uniformity of germination. Soaking the seeds with 100 ppm gibberellin or 1% thiourea can replace low-temperature treatment and obtain the same effect.
