Other claims from this paper (9)
- Intervention effect SRI practices significantly (p < 0.05) improved harvest index, percentage of effective tillers and panicle length in all five rice varieties relative to the current transplanting system.
- Intervention effect SRI practices significantly (p < 0.05) improved various yield components in all five rice varieties relative to the current transplanting system.
- Intervention effect SRI hills with an open-canopy structure had a higher leaf area index than conventional transplanting.
- Intervention effect At the ripening stage, SRI plants had better root growth than CTS plants.
- Intervention effect At the ripening stage, SRI plants had a higher xylem exudation rate than CTS plants.
- Association In SRI plants, higher chlorophyll levels in the lower leaves and a higher photosynthesis rate were associated with better root growth and xylem exudation.
- Mechanism Delayed senescence with enhanced photosynthesis in the lower leaves was responsible for supplying more assimilates to the roots, maintaining their higher activity.
- Intervention effect All rice varieties had 12-42% higher grain yield under SRI than under the current transplanting system.
- Mechanism The SRI features might also contribute to improved grain filling and grain weight in SRI-grown plants.
