Other claims from this paper (9)
- Intervention effect Silicon amendment significantly reduced leaf folder larval survival in rice compared with plants without Si amendment.
- Intervention effect With leaf folder infestation, defense-related enzyme activities increased in rice plants amended with Si.
- Intervention effect With leaf folder infestation, malondialdehyde concentration decreased in rice plants amended with Si.
- Intervention effect Soluble protein content increased with Si addition in rice plants that were not infested.
- Intervention effect In infested rice plants, soluble protein was reduced more with Si amendment than without it.
- Intervention effect Si amendment significantly increased rice leaf Si content regardless of leaf folder infestation.
- Intervention effect Si amendment increased the number and width of silica cells in rice leaves.
- Intervention effect The authors conclude that Si addition enhances rice resistance to the leaf folder.
- Mechanism The authors attribute the enhanced rice resistance to priming of the feeding stress defense system, reduced soluble protein content and cell silicification.
