Fig 4. Average callus mass (mg) produced by a 1 cm by 1 cm leaf square following 2 months on LT-C media.

All 10 genotypes showed a callus response. Control media contained no PGRs and did not induced callus in any of the genotypes. Same letters indicate that means were not significantly different at p = 0.05 as determined by a Tukey-Kramer multiple comparisons test. Error bars represent standard error.
