Other claims from this paper (13)
- Intervention effect Ethephon increased maximum diameter of internodes 7 to 14.
- Intervention effect Ethephon decreased internode length.
- Intervention effect Ethephon decreased plant and ear heights under different nitrogen rates.
- Association Ethephon and nitrogen interacted significantly for internode diameter, length and dry weight per unit length.
- Association Ethephon and nitrogen interacted significantly for breaking resistance.
- Intervention effect Ethephon increased basal internode nitrogen content.
- Intervention effect Ethephon increased basal internode cellulose and hemicellulose contents.
- Association Cellulose and hemicellulose contents decreased as nitrogen application increased.
- Association Internode diameter and dry weight per unit length were positively correlated with breaking resistance.
- Association Basal internode nitrogen content was positively correlated with breaking resistance.
- Intervention effect Ethephon did not significantly increase grain yield and harvest index in 2012.
- Association Grain yield and above-ground biomass rose with increasing nitrogen in both seasons.
- Mechanism Authors suggest ethephon strengthens stalks by improving basal internode morphology and chemistry while maintaining yield under high nitrogen.
