Collection Summary:Barley seedlings were allowed to grow up to two-leaf-stage in the normal hydroponic solution, and then exposed to various treatments after removing endosperm for eliminating its nutrient supply. The treatments included 20% PEG for drought stress, 150 mM NaCl for salt stress, 50 μM Al3+ at pH 4.5 for aluminum stress (Al stress, at the same time the nutrient solution with pH 4.5 and without Al addition used as control), 5 μM CdCl2 for cadmium stress (Cd stress), 0 mM N for N deficiency (replace KNO3, Ca(NO3).4H2O and (NH4)6Mo7O24 with 1mM CaCl2, 1mM KH2PO4 and 0.07 mM H2MoO4), 0 mM P for P deficiency (replace NH4H2PO4 with 1mM NH4Cl), 0 mM K for K deficiency (replace KNO3 with 1mM NaNO3). The hydroponic solution was renewed every four days. After twenty days of the treatments, the plants were harvested, and fresh and dry weight were recorded quickly. The dry tissues were used for mineral element concentration analysis with three biological replicates for each treatment. Meanwhile, fresh tissues were frozen in liquid nitrogen and stored at -80 ℃ for metabolite analysis with four biological replicates for each stress treatment.
