Blue light at 420 nm enhances the effect of 650 nm red light. Photosynthesis occurs at approximately 440 nm. Photosynthesis can be increased up to 400% by means of intermittent light. The early experimenters who reported this effect used a rotating disc with a section removed to chop the light from alamp. They found that 75% of the light from a given source could be blocked without decreasing the rate of photosynthesis. The improved yields produced by intermittent light depends on the frequency of the flashing. A fre- quency of four flashes/minute resulted in 100% increased yields. The amount of work done by the light can be increased by shortening both the light and dark periods. Warburg obtained 100% increased yields by using 133 flashes/second. Emerson and Williams improved the yield over continuous light by 300% to 400% using only 50 flashes/second, and making the light flashes much shorter than the dark peri- ods. The necessary dark period is 72¢NEXUS i iiioooioioouioooeoouoesouououoeosoaououoeo = ——— — — on SaaS... aS_ APRIL - MAY 1994
