↵z Y = drought avoidance, X = LOG(-atmospheric water potential). Regression equations followed by the same letter are not significantly different at p=.O5 as determined by multiple linear regression with indicator variables for species and irrigation level

y Predicted drought avoidance ± 95% confidence interval at -10 and -100 MPa atmospheric water potential.
