Abstract:
... This study investigated the effects of grain sink activity regulated by potassium (K) nutrition during sheath rot disease (ShR) infection on rice milling and appearance quality. We quantified the instantaneous grain sink activity and showed that K application had no significant effects on rice milling and appearance quality in the absence of ShR infection. However, K deficiency substantially aggra ...

Abstract:
... In the rhizosphere of flooded paddy soils, the solubilization, efflux, and uptake of phosphorus (P) are highly intertwined with iron (Fe) redox cycling. However, the direct observation of Fe-P coupling in the rhizosphere is challenging. This study combined high-resolution dialysis (HR-Peeper) and diffusive gradients in thin films (DGT) techniques to capture the one-dimensional distributions of sol ...

To better understand the Sb phytoavailability in rice, we studied Sb accumulation in rice (Zhongjiazao-17, widely cultivated in Hunan province) at different growth stages based on adding SbIII and SbV to waterlogged soils in 10, 50 and 100 mg kg−1 treatment levels. Proportional exogenous SbIII and SbV remained in the soil solution after equilibration. In SbIII treatments, the iron plaque (IP) amou ...

Among micas, trioctahedral micas such as biotite is expected to have a stronger ability to supply nonexchangeable K+ and a higher amount of Cs fixation sites than dioctahedral micas such as illite. Although biotite is predominant in granitic ...
