Fe plaque formations were promoted by Fe application, which was 7.8 and 10.4 times higher at 1 and 2 g kg-1 Fe applications compared to the control Fe treatment. The Quest cultivar exhibited 13% higher iron plaque formation capacity compared to the Langi cultivar in both soil types. These results indicate that enhanced iron plaque formation on the root surface was crucial to reduce the Cd concentration in rice plants, which could be an effective strategy to regulate grain Cd accumulation in rice plants.]]> Wed 28 Sep 2022 15:44:43 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52603 Wed 18 Oct 2023 13:37:49 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51455 Tue 05 Sep 2023 18:15:02 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39889 3 and HClO₄ at 2:1). Concentrations of heavy metals were determined using atomic absorption spectrophotometer (AAS). Principal component analysis (PCA) was performed to reduce multidimensional space of variables and samples. Observed mean concentrations of Cd, Co, Cr, Cu, Mn, Ni, Pb, and Zn were 164, 33.4, 295, 336, 634, 236, 1572, and 546 mg kg−1, respectively. Mean concentrations of all the heavy metals in urban area soil were higher than the WHO permissible limits. Correlation coefficient analysis showed positive correlation among Cd, Co, Cu, Ni, and Pb, whereas no obvious correlation for Cr and Mn was found with any other heavy metal. Zn was positively correlated with Co, Ni, and Mn, whereas negative correlation was found with Cr. Results showed that Pir Wadhai and COD were the most and least contaminated parts of the city, respectively, and this is attributed to the presence and absence of heavy traffic loads and industrial effluents.]]> Thu 21 Jul 2022 09:55:28 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40054 Fri 15 Jul 2022 10:02:32 AEST ]]>
