  • z Each value is the mean of six replicate cross sections of leaf rachises.

  • y Lower leaves were leaf numbers 10, 9, 8, and 7; middle leaves were leaf numbers 5, 4, 3, and 2; upper leaves were leaf numbers 1, 0, −1, and −2, at 3, 8, 13, and 18 weeks, respectively.

  • x Mean of 24 replicate cross sections of leaf rachises, across all four replicate palms.
