3D scatter plot of the tested BIL lines based on the first, second and third principle component in the Exp.1 (A) and Exp.2 (B). T means treatment, LD means leaf drying, LR means leaf rolling, LN means leaf number, DWR means dry weight of root, DWS means dry weight of shoot, RL means maximum of root length, SL means maximum of shoot length, RS ratio means value between maximum root length and shoot length. The confidence ellipse represents the 95% confidence interval for different species
