Web4.1 Spectral interferences resulting from fluorescence of the accessory pigment chlorophyll b, and the chlorophyll a degradation product pheophytin a, can result in overestimation of chlorophyll a concentrations. However, the highly selective optical filters used in this method minimize these interferences. WebFeb 24, 2012 · Chlorophyll breakdown is an integral process of senescence, the final part of leaf development. In this respect, loss of green color visually marks the initiation of dramatic metabolic changes that occur during this final phase of development (Lim et al., 2007). Among other processes, senescence is accompanied by a loss of photosynthetic ...
