Other claims from this paper (9)
- Intervention effect Pathogen inoculation significantly increased four defense enzyme activities in tomato.
- Intervention effect The 1∶ 4 calcium to nitrogen ratio produced the largest defense enzyme increase and highest peak.
- Intervention effect The 1∶ 2 calcium to nitrogen ratio significantly lowered tomato disease index.
- Intervention effect The 1∶ 4 calcium to nitrogen ratio significantly lowered tomato disease index.
- Intervention effect Calcium accumulation in tomato was higher at calcium to nitrogen ratios between 1∶ 2 and 1∶ 4.
- Intervention effect Calcium was evenly distributed among tomato root, stem and leaf at ratios from 1∶ 2 to 1∶ 4.
- Intervention effect The authors inferred that ratios of 1∶ 2 and 1∶ 4 significantly improve tomato leaf mold resistance.
- Intervention effect Excess nitrogen reduced tomato calcium accumulation.
- Intervention effect Excess nitrogen could decrease tomato disease resistance.
