  • b Methods used for measurement are following the description of Schomberg et al. (2003).

  • c The siliques used for measurement were fully developed and nearly mature.

  • Comparisons across a row with different letters (in bold) are significantly different as assessed by Tukey's mean separation test (SAS, 1999).
