(Fig. 7-B). De-epoxidation of the xanthophyll cycle pool
(0.5A+Z)/(V+A+Z) increased with increasing light intensity
(Fig. 7-C). When leaf RWC was below 80%, the de-epoxidation
of the xanthophyll cycle pool (0.5A+Z)/(V+A+Z) was
relatively higher in those leaves that received more light with
identical leaf RWCs (Fig. 7-D).
