Growth parameters of BRZ treated plants in comparison to mock treated plants. Wild-type plants were grown and treated as described in Figure 1. A, Shoot fresh weight. B, Representative plants at day 0, 1, 3, 6, 9, and 14. C, Length of rosette leaves three and four. D, Width of rosette leaves three and four. Data are given as mean ± SE (n =10 plants). Values denoted with an asterisk are significantly different from the wild type (t test, P <0.05).
