Plants can be divided into three categories based on the required day length needed to trigger flowering:. In summary, the most important process triggered by light in plants is photosynthesis. Photosynthesis is a process used by the plant to produce food to help build more plant material.
The faster the photosynthetic rate, the faster the plant grows. The rate of photosynthesis is impacted mostly by the light intensity and quality.
When it comes to flowering, the length of the day is important to know as it directly impacts the timing of flowering for many ornamental crops. For example it is impossible to cause a short-day plant like poinsettia to bloom in the summer under natural conditions.
Where to find our products. Light Quality and Quantity. Light is important as plants use part of the radiant energy emitted by the sun for photosynthesis. Light is usually confused with energy.
