Selection differentials (S) and gradients (b) in non-saline and saline treatments, using the fitness metric relative total pod number. SLA: specific leaf area, LWC: leaf water content, RWC: root water content, SWC: stem water content. T X E: test for change in selection between saline and non-saline treatments. Significance is denoted by t: 0.10 > P > 0.05, *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001. Bold values indicate significance (P < 0.05) with transformed relative total pod number.
