however , about 90 % of the synthesized chlorophyll originates from protochlorophyllide reduction.by a two-minute illumination with 7000 lux 76-88 % of the protochlorophyllide but only 30-60 % of the protochlorophyll is transformed into chlorophyll ( ide ) .as to the question of the hydrogen donor for this transformation , the present investigations have revealed that in red light the protochlorophyll ( ide ) reduction corresponds to the photooxidation of ascorbic acid .
