Concentration of abscisic acid in entire young pods at 9 days after flowering (DAF), and the pod wall and seed of pods at 16 and 23 DAF

Pods were developed from flowers tagged in both well-watered (WW) and water-stressed (WS) plants when the fraction of transpirable soil water (FTSW) of the WS plants was either 1.0 or 0.66 for pods at 9 DAF, and was 1.0 for pods at 16 and 23 DAF. FTSW was maintained at 1.0 in the WW treatment. The FTSW at the time of sampling is given. There was a three-way interaction of genotype×water treatment×FTSW (P<0.05, LSD_0.05=693ng g⁻¹) in the pods at 9 DAF, and of genotype×water treatment×DAF for seed (P<0.05, LSD_0.05=460ng g⁻¹). For pod wall, two-way interactions of genotype×water treatment (P<0.05, LSD_0.05=163ng g⁻¹), genotype×DAF (P<0.01, LSD_0.05=163ng g⁻¹), and water treatment×DAF (P<0.01, LSD_0.05=163ng g⁻¹) were significant, but the three-way interaction was not found
