  1. All values are average values ± the standard deviation. The number of T-RFs is the average for all 102 profiles. The Jaccard and Bray-Curtis similarities are the averages similarities of all 51 duplicate pairs. The T-RF profiles were analyzed with a PDT of 100. Descriptions of the treatments can be found in the Methods section. There was no significant difference between the treatments. All numbers except marked with *were significantly different from the same treatment in the PDT 50 analysis.
