Arrhenius plot, scaled by Tg (x axis) and τTg (y axis), of relaxation time (τ) in molecular glasses of seeds and pollen containing 0.07 g H2O/g dm (open circles). Dashed lines represent relaxation times when γCp is constrained to constant values of 0 (VTF behavior) or 1 (Arrhenius behavior, Tf = 17°C), representing the two extremes of temperature dependency for molecular mobility of glasses.
