Other claims from this paper (19)
- Intervention effect Under water stress, leaf SOD, CAT and POD activities were significantly reduced in maize.
- Association The water-stress decline in protective enzymes was more obvious in the non-drought-resistant cultivar.
- Association The drought-resistant cultivar Shaandan 9 had higher leaf SOD, CAT and POD activities than Shaandan 911.
- Association The drought-resistant cultivar Shaandan 9 had lower leaf MDA content than Shaandan 911.
- Association Protective enzyme activities were lower at the seeding stage than at the elongation and heading stages.
- Association The response of the two cultivars to water stress was weaker at earlier stages than at later stages.
- Association SOD and POD activities reached their peak later than CTA activity.
- Observation MDA content followed a rise-fall-rise pattern over the maize growth period.
- Intervention effect Applications of N, K and glycinebetaine raised protective enzyme activities in water-stressed maize.
- Intervention effect Applications of N, K and glycinebetaine decreased MDA content in water-stressed maize.
- Intervention effect Under water stress, N fertilizer significantly increased protective enzyme activities in the non-drought-resistant cultivar, with differences among N rates.
- Intervention effect Under water stress, N fertilizer significantly decreased MDA content in the non-drought-resistant cultivar, with differences among N rates.
- Association The significant response of the drought-resistant cultivar to N addition was found only at the low N rate.
- Intervention effect At high N rate, leaf SOD, CAT and POD activities were significantly decreased in the earlier growth stage.
- Intervention effect At high N rate, MDA content was increased in the earlier growth stage.
- Association At the later growth stage there was no significant difference between the two N rates.
- Association Glycinebetaine and K fertilizer had a more significant effect than N fertilizer on the rise of protective enzyme activities under water stress.
- Association With adequate water supply, N and K fertilization significantly decreased their effects on protective enzyme activities.
- Association With adequate water supply, the protective function of glycinebetaine vanished.
