二氯喹啉草酮是经中国农业农村部批准登记的茎叶处理除草剂,迄今为止对其潜在的环境污染尚未见报道。本研究建立了一种采用QuEChERS前处理方法结合高效液相色谱-串联三重四极杆质谱 (HPLC-MS/MS) 联用技术检测二氯喹啉草酮在水稻植株、稻谷和土壤中残留的方法,并采用该方法测定了二氯喹啉草酮在水稻植株中的消解动态和最终残留。结果表明:二氯喹啉草酮的进样质量浓度与其峰面积间呈良好的线性相关,R2>...
To understand the functions of transcription factor OsNAC5 in response to abiotic stress, we generated transgenic rice plants with knockdown OsNAC5 by RNAinterfered (RNAi) and overexpressing OsNAC5, a...
Cultivation of rice plants (Koshihikari, IR4595 and IR28) in 250 mmol/L NaCl over 16 days provided interesting profiles of responses on a flow-through electrochemiluminescence (ECL) system with tris(2...
The photosynthetic rate in the flag leaf of rice at the full heading stage was examined in three japonica varieties, Koshihikari, Aikoku and Asanohikari, and the indica high-yielding variety Takanari ...
Potential sink size was correlated with plant nitrogen (N) at late stage of spikelet initiation and flowering, and with growth duration (GD) in DS and WS. The amount of N in plant at critical growth ...
Effect of the starting time of cooling at the flowering stage together with the effects of water temperatures and light conditions after cooling on the fertility percentage were examined. The fertilit...
(1) Variations in single-leaf photosynthesis (CER) among days: CER under saturation light intensity at nearly the same time of several successive days were examined, at three growth stages. (i) CER va...
Under field conditions, the photosynthetic rate of single leaves (CER) declined with time of day even in the case where light intensity at the leaf surface was kept higher than the saturation point. T...
Growth Correlations among Root Number, Root Diameter and Stem Diameter in Some Cultivars of Rice Plants.
In order to clarify the dominant factor responsible for the reduction in photosynthetic rate caused by 1) an increase in leaf-air vapor pressure difference and 2) a decrease in leaf water potential i...
The effect of ambient humidity on the photosynthetic rate of a rice plant population model (area: 120×60 cm, Planting density: about 40 plants/dm2, leaf area index: 6∼7, plant height: about 30 c...
A group of leaves, each of which was situated at the equivalent position on a stem (for instance, the second leaf counted from the uppermost fully expanded leaf of each stem), were chosen and their i...
Single-leaf photosynthesis in situ were observed under field conditions and the regulating factors investigated. The light intensity at the leaf surface was shown to act as the leading factor. Howeve...
The effect of nitrogen top-dressing (ntd) on the gibberellin (GA3, GA) - induced abnormality of spikelets was investigated during the two years, 1986 and 1987, with using the rice cultivar Sachikaze. ...
To determine the promotive effect of isoprothiolane (diisopropyl-1, 3-dithiolan-2-ylidenemalonate, IPT) on ripening in rice plant (Oryza sativa L., cv. Nipponbare), 14C-tracer studies after 14CO2 assi...
