Carbohydrate accumulation was induced in Allium cepa L. cv. Dorata di Parma by the addition of far‐red light throughout the 18 h day. Neither an 18 h‐day without far‐red nor the addition of far‐red light to a 10 h photoperiod could induce the carbohydrate accumulation. The accumulation of reducing sugar takes place both in the leaf‐blades and in the bulb; while there is accumulation of oligosaccharides only in the bulb. The results implicate phytochrome in the promotion of carbohydrate accumulation by far‐red light.
