  • zValues are means ± SE of treatment mean.

  • yValues followed by the same letter are not statistically different as determined by split-plot analysis of variance followed by least significant difference test.

  • xVigor was measured during spring of Year 5. Values followed by the same letter are not statistically different as determined by split-plot analysis of variance followed by least significant difference test.
