Bar plots of the eight control lines for the measured traits after TPS correction. Traits are indicative of a growth and yield, b crown architecture, c responses to stressors, and d vegetative phenology. Wild type WV94 is represented as the light grey bar and the empty-vector controls as the dark grey bars, ordered from EV1 to EV7. Error bars represent 95% confidence intervals. Asterisks indicate Tukey’s HSD mean difference significance (α = 0.05) between the marked empty-vector line and the wild type
