Uniform seedlings of T. apollinea were hydroponically grown in beakers (100 ml) covered with sink strainers in a growth chamber and subjected to different levels of polyethylene glycol (PEG) (0%, 5%, 10%, and 15%) treatment. Potential PEG-induced osmotic stress was evaluated through several plasticity traits such as plant biomass, root nodulation and viability of nodules, and stable isotopes of carbon (δ13C) and nitrogen (δ15N).
