Other claims from this paper (11)
- Intervention effect Coupled Ca and Mg fertilizer addition increased Ca and Mg content of maize kernels.
- Intervention effect Coupled Ca and Mg fertilizer addition increased endogenous hormone components (IAA, GA, ZR), antioxidant enzyme activity and amino acid content of maize kernels.
- Observation IAA, GA and ZR contents of maize kernels continued to rise.
- Observation Superoxide dismutase and catalase activities in maize kernels were elevated.
- Observation Malondialdehyde content in maize kernels increased consistently, which would damage the cell membrane to some extent.
- Observation Leucine showed the highest percentage of essential amino acid components in maize kernels.
- Observation Leucine declined gradually from the filling to the wax ripening stage.
- Association CAT and SOD activities were favourably associated with essential amino acids in maize kernels.
- Association IAA and MDA were negatively associated with essential amino acids in maize kernels.
- Mechanism IAA-CAT-LEU is the dominant pathway driving essential amino acid synthesis: IAA negatively drives CAT activity and CAT controls LEU synthesis.
- Association Ca and Mg content in kernels was positively correlated with antioxidant enzyme activities across increasing fertilizer levels.
