Corn seeds germinate when they absorb enough water and the soil temperature is favorable. Once these conditions are met, the radicle, which is the first root, emerges.
Here's a breakdown of the corn seed germination process:
-
Water Absorption: The corn seed needs to imbibe or absorb water. This process rehydrates the seed's tissues and activates enzymes necessary for germination.
-
Favorable Soil Temperature: Corn has an optimal soil temperature range for germination. If the soil is too cold, the germination process will be slow or may not occur at all.
-
Radicle Emergence: After water absorption and reaching a suitable temperature, the first root, called the radicle, emerges from the seed. This anchors the seed and begins absorbing water and nutrients from the soil. The reference mentions radicle elongation occurring approximately ten days after planting.
In summary, corn seed germination requires adequate water and suitable soil temperatures for the radicle (first root) to emerge.
