- Intervention effect Added NaCl increased sodium ion accumulation in sunflower shoots by 966 percent.
- Intervention effect Added NaCl increased sodium ion accumulation in sunflower roots by 1200 percent.
- Intervention effect Added NaCl reduced shoot potassium ion concentration by 49 percent.
- Intervention effect Added NaCl reduced root K+ by 51 percent.
- Intervention effect Added NaCl reduced the shoot K+/Na+ ratio by 95 percent.
- Intervention effect Si and K application effectively reduced Na+ accumulation compared with salt-stressed plants without supplemental Si and K.
- Intervention effect Si and K application increased K+ concentration and the K+:Na+ ratio in salt-stressed sunflower.
- Intervention effect Si and K application gave a significant improvement in plant growth and yield of salt-stressed sunflower.
- Intervention effect 50 mg Si + 60 mg K2O per kg soil decreased shoot Na+ concentration by 67 percent relative to salt-stressed plants without Si and K.
- Intervention effect The same treatment decreased the shoot Na+/root Na+ ratio by 60 percent.
- Intervention effect The same treatment increased shoot K+ by 198 percent.
- Intervention effect The same treatment increased the shoot K+/Na+ ratio by 812 percent.
- Intervention effect The same treatment increased membrane stability index by 35 percent.
- Intervention effect The same treatment increased relative water content by 26 percent.
- Intervention effect The same treatment increased seed weight per head by 86 percent.
- Association Most plant growth parameters were negatively correlated with Na+ accumulation.
- Association Most plant growth parameters were positively correlated with K+ and the K+/Na+ ratio.
- Mechanism The authors suggest that Si and K mediated reduction in Na+ accumulation and increases in K+ concentration, K+/Na+ ratio, RWC and MSI are the main factors improving the adaptation capability of sunflower to NaCl stress.
