What are the effects of light on the growth of flowering plants

Light is a very important growth condition for flowers, but when giving flowers light you must pay attention to the duration and intensity of light, otherwise it can easily lead to sunburn and leggy growth in the flowers. So what other effects does light have on the growth of flowers?

Light is a necessary condition for photosynthesis in flowering plants. When light is sufficient, photosynthesis is vigorous, more organic nutrients are accumulated, the plant grows and develops robustly, and it blooms abundantly with large flowers. But sun-loving, neutral and shade-tolerant flowers must be treated differently. For example, sun-loving plants such as Chinese rose and pomegranate should have their sunlight needs met. Mountain flowers, rhododendrons (Rhododendron) and Christmas cactus (Schlumbergera) must be shaded from direct strong light in summer, otherwise flowering will be affected.

According to the number of hours of sunlight flowers like, they are divided into long-day, intermediate-day and short-day flowers. Those that need more than 12 hours of light per day to differentiate flower buds are called long-day flowers. Examples include white orchid (Michelia alba), jasmine, magnolia and gladiolus. Intermediate-day flowers are not sensitive to light and can differentiate flower buds under either long days or short days. Examples include carnation and petunia. Short-day flowers need less than 12 hours of sunlight per day, such as chrysanthemum and coral tree (Erythrina).
