Abstract
⺠A model of nonphotochemical (NPQ) quenching control in M. pyrifera is proposed. ⺠NPQ in the qE deficient M. pyrifera is related to the de-epoxidation state ratio. ⺠Violaxanthin and de-epoxidated xanthophylls compete for the quenching sites. ⺠Large xanthophyll cycle pigment pool accelerates the de-epoxidation of violaxanthin. ⺠High light acclimated blades have a large xanthophyll cycle pigment pool.
