Other claims from this paper (18)
- Intervention effect Rice growth was markedly affected by culture solution reaction and light intensity.
- Intervention effect Decreasing light rapidly elongated rice plants.
- Intervention effect Under strong acidity, hydrogen ion concentration limited growth and made the light effect marked.
- Association At pH 5.8, tiller number increased in proportion to light intensity.
- Association The tiller versus light pattern was unclear under higher acidity.
- Intervention effect Light reduced to 0.65 of daylight produced more rice dry matter.
- Intervention effect Further light reduction substantially decreased rice dry matter.
- Association Under higher acidity, grain yield showed a slight reverse relationship to solar radiation.
- Intervention effect With insufficient light, strongly acidic solutions yielded much sugar in rice plants compared with pH 5.8.
- Intervention effect With insufficient light, strongly acidic solutions yielded much starch in rice plants compared with pH 5.8.
- Association Leaf chlorophyll increased in direct proportion to decreasing light intensity at both pH levels.
- Intervention effect Slightly reduced light increased carotine.
- Intervention effect Slightly reduced light increased xanthophyll.
- Association Plant nitrogen partly tracked decreasing light intensity.
- Association Plant phosphorus showed a similar relationship to decreasing light intensity.
- Association Plant potassium showed a similar relationship to decreasing light intensity.
- Association Plant iron was lower with decreasing light, particularly in strongly acidic medium.
- Observation The authors concluded that rice grows favorably with low solar radiation under strong acidity.
