Other claims from this paper (14)
- Intervention effect Salinity reduced tomato shoot biomass by 50–60%.
- Intervention effect Salinity reduced photosynthetic area by 20–25%.
- Intervention effect Salinity decreased leaf expansion.
- Intervention effect Salinity delayed leaf appearance.
- Intervention effect Root growth was less affected by salinity than shoot growth.
- Intervention effect ABA concentrations increased in roots, xylem sap, and leaves after one day of salinization.
- Intervention effect ACC concentrations increased in roots, xylem sap, and leaves after 15 days of salinization.
- Intervention effect Salinity decreased total plant Z+ZR content.
- Intervention effect Salinity induced ZR conversion to Z, especially in roots.
- Intervention effect Root cytokinin concentration increased relative to leaves under salinity.
- Intervention effect Salinity decreased IAA concentration in leaves.
- Intervention effect IAA accumulated in roots under salinity.
- Mechanism Authors proposed that shoot-to-root auxin transport caused lower cytokinin content and root-to-shoot cytokinin transport.
- Mechanism Authors proposed that leaf and root auxin to cytokinin ratios explain reduced shoot vigor and altered root allocation.
