Abstract

Chlorophyll(ide) fluorescence emission decreases at room temperature during completion of protochlorophyll(ide) reduction. The process responsible for this quenching is parallel to the P688-676 →P695-682 transition. It proceeds equally well in darkness and in the light. It consists in a decrease of the fluorescence yield of chlorophyll(ide) in P695-682. Apparently, room temperature P695-682 fluorescence is regulated by a conjunction of factors such as energy transfers and photobiochemical activities.

摘要

叶绿素(原)荧光发射在室温下于原叶绿素(原)还原完成过程中降低。导致这种猝灭的过程与 P688-676→P695-682 转变平行。它在黑暗中和光下同样良好地进行。它包括 P695-682 中叶绿素(原)荧光产率的降低。显然,室温 P695-682 荧光受能量转移和光生化活性等因素的共同作用调节。
