Other claims from this paper (14)
- Intervention effect Cold stress increased oxidative leaf damage by 133% in nitrate-treated maize.
- Intervention effect Cold stress reduced shoot biomass by 25% in nitrate-treated maize.
- Mechanism The shoot biomass reduction under cold stress is explained by reduced acquisition of phosphate, zinc and manganese.
- Intervention effect Supplying N as ammonium improved the zinc and manganese nutritional status of maize.
- Intervention effect Supplying N as ammonium increased shoot ABA concentration by 33% in maize.
- Intervention effect Supplying N as ammonium moderately increased detoxification of reactive oxygen species in maize.
- Intervention effect Use of N as ammonium increased root auxin (IAA) concentration by 76% in maize.
- Intervention effect Use of N as ammonium increased expression of the auxin-responsive genes ZmTSA, ZmPIN1a and ZmARF12 in maize.
- Association An increased ABA/cytokinin ratio and higher jasmonic and salicylic acid levels were associated with increased ROS detoxification in maize.
- Intervention effect Additional supplementation with Zn and Mn increased shoot IAA, root length and total antioxidants in maize.
- Intervention effect Additional supplementation with Zn and Mn gave the highest shoot biomass production in maize.
- Intervention effect Inoculation with the microbial consortium promoted root colonization by T. harzianum OMG16 in combination with ammonium fertilization (+140%) in maize.
- Intervention effect A pre-selection trial found superior cold-protective performance for a consortium of Trichoderma harzianum OMG16 and Bacillus spp. with Zn/Mn supplementation.
- Recommendation Mitigation of cold stress in maize relies on a strategic combination of stress-protective nutrients with selected microbial inoculants.
