Seng Shan 2012
Other claims from this paper (19)
- Intervention effect Topdressing exogenous spermidine increased the average yield of maize DH662 by 12.9% after waterlogging stress.
- Intervention effect Topdressing exogenous spermidine increased the average yield of maize XD20 by 10.8% after waterlogging stress.
- Intervention effect Waterlogging at the seedling to jointing stage had more influence on the two maize varieties than at other stages.
- Intervention effect The effects of exogenous spermidine were best when applied at the seedling to jointing stage.
- Intervention effect Topdressing exogenous spermidine improved the utilization efficiency of light energy in different growth stages.
- Intervention effect Exogenous spermidine increased leaf Fv/Fm, ΦPSII and qP.
- Intervention effect Exogenous spermidine reduced Ci and qN.
- Intervention effect Exogenous spermidine significantly increased SOD activity in DH662 by 14.5% compared with the waterlogging treatment.
- Intervention effect Exogenous spermidine significantly increased CAT activity in DH662 by 19.9% compared with the waterlogging treatment.
- Intervention effect Exogenous spermidine significantly increased SOD activity in XD20 by 4.6% compared with the waterlogging treatment.
- Intervention effect Exogenous spermidine significantly increased CAT activity in XD20 by 18.2% compared with the waterlogging treatment.
- Intervention effect Exogenous spermidine increased the average activity of IDH in both maize cultivars by 26.1%.
- Intervention effect Exogenous spermidine increased the average activity of SDH in both maize cultivars by 19.6%.
- Intervention effect APX activity was not significantly increased by exogenous spermidine.
- Intervention effect Exogenous spermidine repressed cell membrane oxidation in maize.
- Intervention effect Exogenous spermidine increased the average root activity in DH662 and XD20 by 12.9%.
- Intervention effect Exogenous spermidine decreased MDA content by 23.9%.
- Mechanism Topdressing exogenous spermidine improves leaf and root physiological functions, resulting in lower yield losses caused by waterlogging.
- Intervention effect The sensitivity of different maize varieties and growth stages to spermidine was different.
