Abstract
Respiratory activity of green tobacco callus tissue from the pith of Nicotiana tabacum var. Samsun was influenced by light. Interruption in the light period resulted in a decrease in respiratory activity after a lag period of about 2 hr. The respiration level increased on re-illumination and was restored to its original level after 2–3 hr. The light effect that increased respiratory activity was enhanced by sugar in the medium and by increasing the light intensity. However, the response to light was not affected by an inhibitor of photorespiration and was suppressed completely by an inhibitor of photosynthesis.
