Fluorescence and Photochemical Investigations of Phytochrome in Higher Plants
Figure 5
Temperature dependence of the fluorescence quantum yield ( nm, nm) of the phytochrome Pr form in pea stems and oat coleoptiles of 7-day-old etiolated seedlings: (a) versus temperature; (b) ln [(1/) −1−] versus 1/T (, where is the rate constant of the temperature-independent excitation degradation and is the radiative rate constant. Quantum yield, , at 85 K is equal to 0.25 and for pea and oat is equal to 2 and 3, respectively (b, curves 1 and 2). (From [35]).
