Table 1 The phenotype analysis of Petunia x hybrida ‘Mitchell Diploid’ (MD) and ir-PhCSE T1 plants. Data represent mean ± SD (n = 3). The means were separated by one-way ANOVA and statistically significant differences (p < 0.05) were identified by Tukey’s test. The results were shown by letters to represent differences among groups
