Other claims from this paper (7)
- Intervention effect Low oxygen combined with low nitrogen and 70 meq/1 NaCl caused the greatest reduction of sunflower growth.
- Intervention effect Sunflower plant height and dry weight decreased with each type of stress.
- Intervention effect Low nitrogen and excess salt reduced sunflower leaf number.
- Intervention effect Low oxygen increased the Na and N‐NO3 content of sunflower leaves.
- Intervention effect Potassium to sodium ratios in sunflower decreased with greater EC values of the nutrient solution and low soil ODR.
- Method / resource Ion accumulation is an earlier indicator of sunflower stress than plant growth.
- Observation Seed germination of sunflower was excellent in all treatments.
