Article Catalog

Sunflower seeds are generally referred to as their fruits. Academically called achenes, commonly known as melon seeds and sunflower seeds. But the fruit includes three parts: pericarp, seed coat, and embryo. The seed specifically refers to its embryo, which is the melon seed kernel. The seeds can be eaten and extracted for oil, making them a popular snack and source of cooking oil. Sunflowers usually germinate around 5-7 days. When sowing sunflowers, it is necessary to ensure that the ground temperature is within a certain range, which will help the seeds germinate smoothly and quickly.

1. Sunflower seeds

Sunflower seeds are generally considered to be its fruits. Academically called achenes, commonly known as melon seeds and sunflower seeds. But the fruit includes three parts: pericarp, seed coat, and embryo. Sunflower seeds specifically refer to its embryo, which is the melon seed kernel. The seeds can be eaten and extracted for oil.

3. How many days does it take for sunflower to sprout

Sunflowers usually germinate around 5-7 days. When sowing sunflowers, ensure that the ground temperature is within a certain range, which will help the seeds germinate smoothly and quickly. When the ground temperature is above 2°C, the seeds will germinate; when the ground temperature is 4 to 5°C, the seeds can germinate and take root; when the ground temperature reaches 8 to 10°C, the seeds will germinate and emerge. The optimal temperature for seed germination is 31-37°C, and the highest temperature can reach about 38-44°C.
