Fig. 7: Relationship between soybean yield, yield coefficient-of-variation (CV), and drought stress.

From: Anticipated changes in soybean drought stress and yield stability under future climates in Northeast China

a Soybean yield and yield CV. b Soybean yield and drought stress. c Yield CV and drought stress. I, Xinganling suberegion; II, Sanjiang plain; III, Songliao plain; IV, Changbaishan suberegion; V, Liaodong subregion. The solid lines are linear least-squares fit lines, and shaded areas indicate the 95% confidence interval of fit lines. The ** indicate significance of correlation coefficients (r) at the p < 0.01 level based on Student’s t-test, and p values indicate significance of linear of the regression based on F-test.
