To this end, UPE was measured (50 seedlings in one Petri dish, duration: approx. 16.6-28 h) from samples of three groups: (i) control (group C, N = 9), (ii) treated with 25 ppm of PD (group G(25), N = 32), and (iii) treated with 150 ppm of PD (group G(150), N = 23). For the multifractal analysis, the following steps where performed: (i) each UPE time series was trimmed to a final length of 1000 min; (ii) each UPE time series was filtered, linear detrended and normalized; (iii) the multifractal spectrum (f(alpha)) was calculated for every UPE time series using the backward multifractal detrended moving average (MFDMA) method; (iv) each multifractal spectrum was characterized by calculating the mode (alpha(mode)) of the spectrum and the degree of multifractality (Delta alpha); (v) for every UPE time series its mean, skewness and kurtosis were also calculated; finally (vi) all obtained parameters where analyzed to determine their ability to differentiate between the three groups.
