The arrangement of chloroplast in cells influences the reabsorption of chlorophyll fluorescence emission. The effect of desiccation on the chlorophyll fluorescence spectra of Rhizomnium punctatum leaves
Original language description
Chlorophyll fluorescence spectra measured with leaves are distorted by the effect of fluorescence reabsorption. A heterogeneous theoretical model describing the effect of chloroplast arrangement in a cell on the distortion of chlorophyll fluorescence spectra due to reabsorption was formulated. Desiccation of leaves of a moss Rhizomnium punctatum was carried out as a simple model experiment. The parameters entering the model (maximal number of chloroplasts forming columns in a cell, chloroplast size andchlorophyll concentration in a chloroplast) were estimated by means of light microscopy and spectrophotometry. During the desiccation, a grouping of chloroplasts was observed by light microscopy and the chlorophyll fluorescence emission and excitation s pectra of the leaves were measured at room temperature and at 77 K. The leaves were infiltrated with DCMU. The ratio F685/F735 of the main emission bands decreased by about 50 % at room temperature and by about 30 % at 77 K upon decreasing
