Other claims from this paper (15)
- Intervention effect At leaf day 60, organic fertilizer gave 136. 1% higher chlorophyll content than chemical fertilizer.
- Intervention effect At day 75, organic fertilizer gave 135. 3% higher photosynthetic rate than chemical fertilizer.
- Intervention effect At day 75, organic fertilizer gave 84. 5% higher conductance than chemical fertilizer.
- Intervention effect At day 75, organic fertilizer gave 51. 3% higher transpiration than chemical fertilizer.
- Intervention effect Organic fertilizer gave Y[Ⅱ] 22. 2% higher than chemical fertilizer.
- Intervention effect Organic fertilizer gave q L 39. 5% higher than chemical fertilizer.
- Intervention effect At the 45 day stage, organic fertilizer lowered NPQ by 23. 2% against chemical fertilizer.
- Association Starch grains increased with leaf age.
- Association The starch-grain-to-chloroplast area ratio increased with leaf age.
- Intervention effect Chemical fertilizer produced a significantly higher leaf Ra value than organic fertilizer, especially at day 45.
- Intervention effect Organic fertilization gave fusiform chloroplasts with higher aspect ratio.
- Intervention effect Chemical fertilizer gave round chloroplasts with lower aspect ratio.
- Mechanism Authors interpreted organic fertilization as delaying senescence and enhancing leaf light utilization.
- Observation The Ra differences could not establish superior starch synthesis under chemical fertilizer.
- Intervention effect Organic fertilizer significantly increased the ratio of chloroplast grana with 10 lamellae.
