An albino mutant (KU No. 1246) of sand oats was grown in several culture media or under different temperatures, and chlorophyll formation was observed in their leaves.Higher concentrations of glucose (0.3-0.5M) in the basal medium resulted in a greater production of chlorophyll when albinos were grown at 21°C. On the other hand, albinos cultured under higher temperatures (21-30°C) also produced a larger amount of chlorophyll. However, the chlorophyll content of albino leaves was less than 10% of that of normal greens grown under the same conditions.A similar increase of chlorophyll in albino was also observed in the media containing 0.1M glucose and a high concentration of mannitol (0.3-0.4M). Thus, it is presumed that a part of the effect of glucose might be of providing the medium with a high osmotic pressure which could be substituted by mannitol.A vitamin-mixture and indole-3-acetic acid seem to be slightly effective on the chlorophyll formation in the albino plants.
