Other claims from this paper (16)
- Intervention effect Excessive nitrogen fertilizer reduced the biomass of tomato seedlings.
- Intervention effect Soil moisture deficiency reduced the biomass of tomato seedlings.
- Intervention effect Microbial dilution (EM) increased tomato plant biomass by 5.2% compared with CK (adequate water with tap water).
- Intervention effect Nitrogen application increased chlorophyll relative content (SPAD) in tomato seedlings.
- Intervention effect The maximum net photosynthetic rate (Pc) of tomato decreased with nitrogen application.
- Intervention effect The maximum net photosynthetic rate (Pc) of tomato increased with EM application.
- Intervention effect Excessive nitrogen application increased plant nitrate reductase activity (NR) in tomato.
- Intervention effect Plant NR in the excessive-nitrogen (N) treatment was 13.0% higher than in CK.
- Intervention effect Plant NR in nitrogen application with water deficiency (WN) increased 34.0% compared with water deficiency (W).
- Intervention effect In the EM-N treatment, excessive nitrogen increased plant nitrate reductase activity by 22.9% relative to the corresponding moderate-nitrogen treatment (EM).
- Intervention effect In the EM-WN treatment, excessive nitrogen increased plant nitrate reductase activity by 28.6% relative to the corresponding moderate-nitrogen treatment (EM-W).
- Intervention effect Activities of the antioxidant enzymes SOD, POD and CAT increased significantly in the four nitrogen application treatments.
- Intervention effect Soil moisture and nitrogen fertilizer significantly reduced the osmotic potential (πFT) of tomato seedlings.
- Intervention effect Soil moisture and nitrogen fertilizer significantly increased the osmotic concentration (Cosm) and concentration difference (ΔCosm).
- Intervention effect The relative water content of apoplast (ζap) decreased, indicating that water deficiency and excessive nitrogen reduced water absorption and retention capacity of tomatoes to a certain extent.
- Intervention effect Microbial dilution alleviated excessive nitrogen fertilizer and water stress to some extent, but the effect was not significant.
