Other claims from this paper (13)
- Intervention effect N application significantly increased seedling height, fresh weight and dry weight after 12 days compared with the zero N group.
- Intervention effect The increases in seedling growth indicators with N application after low temperature stress were relatively higher than with N application at normal temperature.
- Intervention effect Antioxidant enzyme activity of rice seedlings increased significantly after N application.
- Observation Soluble protein content of rice seedlings showed a slow decrease.
- Observation H2O2 and MDA content of rice seedlings decreased significantly.
- Intervention effect Nitrogen increased the expression of genes related to NH4+ and NO3− uptake and transport in rice.
- Intervention effect Nitrogen improved the activity of nitrate reductase (NR) and glutamine synthetase (GS) in rice.
- Mechanism N is asserted to affect GA3 and ABA levels by regulating the anabolism of GA3 and ABA.
- Intervention effect With N application, rice seedlings had high ABA and low GA3 levels from day 0 to day 6.
- Intervention effect With N application, rice seedlings had high GA3 and low ABA levels from day 6 to day 12.
- Association Rice variety B116 showed more obvious growth recovery and stronger growth-related physiological reaction than B144 after N application.
- Recommendation N application of 40 kg hm -2 was more conducive to rapid recovery of rice growth after stress.
- Mechanism Appropriate N application promoted rice seedling growth recovery after low temperature stress mainly by increasing activities of antioxidant and nitrogen metabolizing enzymes and regulating GA3 and ABA levels.
