It was investigated whether monochromatic light beyond 700 mu can bring about light dependent glucose uptake in the absence of 02 and C02 It was found that glucose assimilation proceeds at a high rate even beyond 700 mu The uptake at 711 mu is 20 to 30 times higher in relation to photosynthesis at this wavelength as compared to 658 mu It was shown that there is no significant difference in the products formed from the assimilated glucose whether white light, 658 or 711 mu. light was used Approximately 80 % entered into starch + sucrose.
