How Do Plants Detect And Manipulate Light?
Answer:
Learning these facts about the responses of plants to length of daylight made something else apparent. Plants must have something in them that detects the change in length of daylight and that causes them to respond as expected. Just recently this substance, called "phytochrome," has be isolated.
Phytochrome is a bluish, light-sensitive pigment that absorbs red light. It has be shown that many plants, when exposed to the red wavelength of light, mature more hastily. Somehow the light acts on the phytochrome to regulate a plant's growth changes, from core stage to maturity. But it is not understood just how this is skilful.
Many gardeners now use to good advantage this ease about the responses of plants to light. By adjusting all along exposure to light they can make a plant bloom when they want it to. Thus in winter they delight in flowers that normally grow only in summer, and those that generally bloom in autumn they may have in other season.
A chrysanthemum, for instance, is normally an autumn-flowering plant. But it can be made to bloom in summer. Just cover it with a cardboard carton contained by the late afternoons, and remove the carton in the morning. The extended period of fogginess will cause the chrysanthemums to react as if it were autumn, and they will bloom near the summer flowers
