↵^z Letters used for palm identity correspond to letters used for palm identity in Figure 1.
↵^y Measurement height (MH) is from the soil line.
↵^x For each palm, minimum resistance value across all MHs and maximum resistance value across all MHs were used to calculate quotient.
↵^w For each palm, value is mean of the difference between maximum resistance and minimum resistance at each MH.
