Reasons for low germination rate of celery seeds

Celery seed sowing, sometimes there will be incomplete germination, irregular germination, difficult to germinate. When we encounter such a problem, we generally have to find the problem from the seed first, and then find the problem from the seed processing process. And whether the seeds are handled properly. And then there is whether the environment provided is suitable. Let's take a look at why right away.

1. Seed problem

It may be that the seed itself is not mature enough, the harvest is too early, or the time of seed collection is affected by the weather, and the seed maturity is not enough due to heavy rain. The flowering time of different flower branches is different, and the seed ripening time is different, so the seed with late flowering after harvest is not mature enough. It is rainy in early spring and the seeds mature later.

2. Improper processing

After harvest, the seeds are not dried in time, or they are not dried to the standard dryness. When the seeds are stacked and impermeable, the moisture of the seeds can not be released, and they do not stop breathing and begin to breathe aerobically, so the vitality of the seeds becomes weaker. If it is stored for too long, it will be even weaker. If the sun is too hot, the seeds will be hurt and it will be difficult to germinate.

3. Be dormant

If the seed dormancy is not broken successfully, the seed is in a dormant state and will not germinate and must go through dormancy. Or it can only sprout by artificially breaking dormancy. Dormant seeds rarely germinate. Dormancy may not be germinated by using growth regulators, or by low temperature. In the fridge.

4. Insufficient conditions

It needs enough water, suitable temperature, sufficient oxygen and good light to sprout. It is also necessary to provide good soil environment and cultivation substrate. Seed germination requires a temperature of more than 15 degrees, preferably about 20 degrees. It sprouts slowly below 15 degrees. 30 degrees can't sprout. When the temperature is high, the moisture will increase rapidly, and after covering the soil, there will be insufficient oxygen and light.

In general, seeds cannot germinate because of these wishes, not only celery, but also other vegetable seeds. Sowing attention to these effects on seed collection should also be done well.
