Light chasers: the mystery of sunflower growth

Sunflowers are famous for their unique positive (heliotropism), and they are like loyal followers always chasing the pace of the sun. In the early morning, the green flower plate will face the east to welcome the first ray of morning light; when the evening comes, it slowly turns to the west to see off the sunset. This wonderful phenomenon is not accidental, but is driven by complex internal mechanisms.

After a long period of observation, scientists have found that plants contain a group of sensor cells that can sense changes in light intensity. These receptors can capture sunlight from different directions and adjust the distribution of auxin in the stem accordingly. More inclination to the east during the day leads to the accumulation of more hormone substances in the lower area, thus stimulating the acceleration of elongation to form a curved form; the lack of light at night weakens the inhibitory effect of the whole plant to restore the upright posture. In this way the cycle is repeated until the end of the ripening period.

Agronomists are constantly working to improve cultivation techniques in order to produce healthier, high-yielding sunflower varieties. For example, a scientific and reasonable irrigation system is adopted to ensure sufficient water supply without wasting resources. The selection of excellent substrates and precise fertilization scheme to ensure balanced nutrition intake to support healthy growth; Reasonable dense planting increases the number of effective individuals per unit area and thus improves the overall benefit, and other measures work together to promote the rapid progress of crop quality.
