Clogoddess writes: Flowering plants (in other words, food) often flowers based on the day length. Research news! Scientists find that plants with day length awareness detect BLUE light. Atmospheric scattering is greatest in the blue/violet end of the spectrum(*) making plants' choice of blue light the most sensitive color choice to detect seasonal change. Smart vegetables? I for one munch cheerfully on our tasty lettuce overlords!
- * The degree of scattering decreases in the following order: UV-B > UV-A > violet > blue > green > yellow > orange > red > infrared; source: http://almashriq.hiof.no/lebanon/600/610/614/solar-water/idrc/01-09.html
