  • Calculated values of the lumen resistance Rlumen, plate resistance Rplate, agglomeration resistance Rplug, and total resistance R determined from Equations (A3), (A4), (A5), and (A2) (see Supplemental Appendix 1 and Supplemental References 1 online). The results are given for two values of the effective sieve tube diameter de and three values of the agglomeration opening diameter do. de = 3.0 μm corresponds to a completely empty sieve tube, and de = 2.4 μm corresponds to a sieve tube with only 65% of the area open to flow. Results marked with an asterisk indicate the measured value of do = 1 μm. Results marked with (†) indicate the case where no At SEOR1 agglomerations are present.
