Soil relative water content at 20 DPA. Soil relative water content was measured at 2 m depth of soil in the control (CK) and drought treatment (T) groups. Statistically significant differences compared to the control were calculated based on an independent Student’s t-tests. Asterisks indicate significant different (*p < 0.05; **p < 0.01). Error bars indicate standard errors of three biological replicates
