| Shoots | Roots | Nodules | |
|---|---|---|---|
| Pisum sativum | |||
| Pots | −19.9 ± 9.8 (A) | 1.6 ± 14.4 (A) | −41.2 ± 11.9 (A) |
| RhizoTube | −32.6 ± 13.9 (B) | −7.4 ± 14.2 (B) | −36.9 ± 12.8 (A) |
| Medicago | |||
| Pots | −26.5 ± 30.0 (A) | −11.5 ± 34.5 (A) | −15.9 ± 46.1 (A) |

Modulation of biomass allocation to shoot, roots and nodules of pea (Kayanne genotype) and Medicago truncatula plants subjected to a water stress versus well-irrigated plants was measured as the ratio of the difference in biomass of shoots (BMS), roots (BMR) or nodules (BMN) between water stress (WS) and well watered (WW) plants to the biomass of well watered plants (n = 5). As an example for shoots, (BMSWS − BMSWW) × 100/BMSWW
