Light

Cards (5)

  • The intensity of light affects the rate of photosynthesis
  • Brighter light = more rapid photosynthesis
  • Photoperiodism (daylength) affects the growth and development of crops
  • Examples for photoperiodism ---
    Oats need a longer period of light
    maize needs a shorter period of light
    Cows need long day length for milk production
    Poultry grow best in shorter days while egg production needs longer days
    Sheep mate when days get shorter
  • this can be controlled by artificial lighting-
    can be used to extend the growing season of salad crops in greenhouse
    or autumn lighting conditions for a second sheep mating season
