Dry weight and nitrogen allocation in response to environmental stresses. For all the stresses except low N, plants were grown until bolting in the control condition and then transferred to stress conditions (drought, defense, dark, and heat) until seed maturity. The low N condition was applied from sowing. (A–C) The DW of rosette (A), stem (B), and seeds (C) measured at harvest. (D–F) Proportion of total aboveground plant N in rosette (D), stem (E), and seeds (F) of plants grown in the six environments. Means ±SE for the eight genotypes are shown. Asterisks indicate the significance of the difference between the means of the control and stress conditions: *P<0.05, ***P<0.001, n≥112.
