  1. ROIs = number of regions of interest at different positions on stem, sv = trapping probability per unit time; V = velocity up stem, slope of linear regression of position vs mean arrival time; s = Trapping probability per unit length of stem. Corresponding values in units of cm and min, mean(s.d., n = 3): sv = 0.0152(32) 1/min, V = 2.21(1.08) cm/min, s = 0.0084(49) 1/cm.
