What are the reasons for the low germination rate of celery seeds

When sowing celery seeds, sometimes there are also problems of incomplete germination, uneven germination, and difficulty germinating. When encountering such problems, generally one should first look for problems in the seeds themselves, and next find problems in the seed processing process. And whether the seed treatment was appropriate. Then there is whether the environment provided is suitable. Let's take a look at the reasons right away.

1. Seed problems

It may be that the seeds themselves are not mature enough, were harvested too early, or the seed collection time was affected by weather, with heavy rain affecting them, so the seeds were not mature enough. Different flower stalks bloom at different times, and the seeds mature at different times, so after harvest there are seeds from late-blooming flowers that are not mature enough. In early spring with more rain, the seeds mature a bit later.

2. Improper processing

If harvested seeds are not dried in time, or are not dried to the standard dryness, the seeds are stacked and not ventilated, the seed moisture cannot be released, respiration does not stop, and aerobic respiration begins, so the seeds' vitality weakens. If stored too long, they become even weaker. If dried too much, the seeds are damaged and it is very difficult for them to germinate.

3. Being dormant

If the seed dormancy has not been successfully broken, the seed is in a dormant state and will not germinate; it must pass through dormancy. Or the dormancy must be artificially broken for it to germinate. Dormant seeds rarely germinate. If they may not germinate, growth regulators can be used to break dormancy, and low temperature can also be used to break dormancy. This is done in the refrigerator.

4. Insufficient conditions

Sufficient water, suitable temperature, sufficient oxygen, and good light are needed for germination. A good soil environment and growing medium must also be provided. Seed germination requires a temperature above 15 degrees, preferably around 20 degrees. Below 15 degrees, germination is very slow. At 30 degrees, they cannot germinate. When the temperature is high, water also evaporates faster, and if the soil covering is too thick, oxygen and light are insufficient.

Generally, if seeds cannot sprout, these are the reasons, not only for celery, but for other vegetable seeds as well. When sowing, pay attention to these effects, and the preparatory work for seed collection must also be done well.
