Effect of 45 days exposure to thermotherapy, etiolation, or combination of both treatments on meristem rescue ratio, percentage of surviving meristems, and efficiency of PPV elimination (A) as well as HSVd elimination (B). Error bars represent the standard error. The numbers indicate the initial treated shoots on yellow bars, the total number of isolated meristems on green bars, and the number of established lines on red bars. Different letters indicate significant differences (P < 0.05) between treatments, after specific contrast, for each evaluated parameter
