t0“[Effects of light quality on rice seedlings growth and physiological characteristics].”
e0“By using light emitting diode (LED) to accurately modulate spectral energy distribution, and with fluorescent light as the control, this paper studied the effects of light quality on the seedlings growth and physiological characteristics of rice cultivars 'Wuyunjing 7' and 'Kangyou 63'”
e5“Red-blue LED increased the root number, stem diameter, healthy index, root activity, and root soluble sugar content at three-leaf stage and the fresh mass, dry mass, healthy index, and leaf soluble sugar and sucrose contents at five-leaf stage significantly”

- Intervention effect Light quality had significant effects on rice seedling growth, with differences between growth stages.
- Intervention effect Blue LED significantly inhibited rice seedling height growth.
- Intervention effect Blue LED increased the leaf soluble protein content of 'Wuyunjing 7' at five-leaf stage.
- Intervention effect Blue LED increased the healthy index of both rice cultivars at five-leaf stage.
- Intervention effect Red LED increased the stem diameter and healthy index at three-leaf stage.
- Intervention effect Red LED significantly increased leaf soluble sugar and starch contents at five-leaf stage.
- Intervention effect Red-blue LED increased root number, stem diameter and healthy index at three-leaf stage.
- Intervention effect Red-blue LED increased root activity and root soluble sugar content at three-leaf stage.
- Intervention effect Red-blue LED increased leaf soluble sugar and sucrose contents at five-leaf stage.
