Both red and blue light pulses are separately shown to retard dark-stimulated chlorophyll loss of papaya leaf discs suggesting participation of phytochrome and blue light photoreceptors in regulating the pigment loss. The red light effect is fully reversible by far-red light. The partial failure of far-red pulses to reverse the action of blue light suggests that blue light effect may not be entirely through the phytochrome action. The apparent ineffectiveness of continuous white light to check the chlorophyll loss is attributed to a balance of photooxidation and photoprotection of the pigment.

The interaction of blue light and kinetin at its different concentrations suggests that the effect of interactions is additive. The blue light effect in retarding chlorophyll loss is partly independent of the hormone level.
