Abstract:
Over the last two centuires, the natural night-time environment has been drastically altered by the proliferation of man-made artificial lighting. At global level artificial lighting is rapidly increasing by around 2.2% per year. With increasing urbanization and increasing human demand for intensive night illumination, there has been growing concern about effects of ever-increasing illumination at night (termed as light pollution) on living organisms. Excessive artificial light added to the nocturnal landscape is a serious ecological burden on the environment, with adverse impacts on the biorhythms of living organisms. The investigations about environmental implications of light pollution are generally focused on humans and animals and are less frequent in the case of plants. As already known, any disturbance in the circadian clock in animals including humans can disrupt hormone production, cell regulation, and other biologic activities it can also affect plants in the similar patterns. The role of light in the life of a plant is dual. On one hand, light provides the energy necessary for photosynthesis, on the other it is also perceived as a signal. Plant growth and development are influenced by light spectral quality, quantity and duration of light and dark periods.This paper provides a review of the current research on various impacts of light pollution on morphology, physiology and ecology of plants with special emphasis on urban flora.
