Light Interaction with Plant Architecture: Impact of Buildings and Artificial Lighting on Plant Development

The document reviews the fundamental role of light—natural and artificial—in driving plant development processes including germination, growth, and flowering. It describes how plants sense light characteristics (direction, duration, spectral composition) as signals, and how interactions between solar radiation and chlorophyllous organs within plant canopies create spatial and temporal variations in light quality. The text contrasts the spectral and intensity differences of natural light (modified by sky conditions and building shadows) with those of various artificial light sources, illustrating applications in urban environments such as sports turfgrass lighting and highlighting notable trees.
