| effects of an iron-silicon material, a synthetic zeolite and an alkaline clay on vegetable uptake of as and cd from a polluted agricultural soil and proposed remediation mechanisms. | economic and highly effective methods of in situ remediation of cd and as polluted farmland in mining areas are urgently needed. pot experiments with brassica chinensis l. were carried out to determine the effects of three soil amendments [a novel iron-silicon material (ism), a synthetic zeolite (sz) and an alkaline clay (ac)] on vegetable uptake of as and cd. sem-eds and xrd analyses were used to investigate the remediation mechanisms involved. amendment with ism significantly reduced the conce ... | 2017 | 27530933 |
| accumulation of cr, cd, pb, cu, and zn by plants in tanning sludge storage sites: opportunities for contamination bioindication and phytoremediation. | tanning sludge enriched with high concentrations of cr and other metals has adverse effects on the environment. plants growing in the metalliferous soils may have the ability to cope with high metal concentrations. this study focuses on potentials of using native plants for bioindication and/or phytoremediation of cr-contaminated sites. in the study, we characterized plants and soils from six tanning sludge storage sites. soil in these sites exhibited toxic levels of cr (averaged 16,492 mg kg(-1 ... | 2016 | 27552994 |
| slow-release nitrogen fertilizers can improve yield and reduce cd concentration in pakchoi (brassica chinensis l.) grown in cd-contaminated soil. | cadmium (cd) pollution in vegetable crops has become a serious problem in recent years. owing to the limited availability of arable land resources, large areas of cd-contaminated lands are inevitably being used for the production of vegetables, posing great risks to human health via the food chain. however, strategies to improve yield and reduce cd concentration in crops grown in contaminated soils are being developed. in the present study, using pot experiments, we investigated the effects of t ... | 0 | 27677996 |

| effects of glucose on the uptake and metabolism of glycine in pakchoi (brassica chinensis l.) exposed to various nitrogen sources. | plants can absorb amino acids as a nitrogen (n) source, and glucose is an important part of root rhizodeposition and the soil sugar pool, which participates in the regulation of plant growth and uptake. in pakchoi, the effect of glucose concentration on the glycine n uptake from a nutrient mixture composed of glycine, ammonium, and nitrate, or from a single n solution of glycine alone was studied using specific substrate (15)n-labeling and (15)n-gas chromatography mass spectrometry. | 0 | 28253854 |
| transcriptomic profiling of two pak choi varieties with contrasting anthocyanin contents provides an insight into structural and regulatory genes in anthocyanin biosynthetic pathway. | the accumulation of anthocyanin in horticultural crops not only improves their stress tolerances but also their nutritional values. many key regulatory and structural genes in anthocyanin biosynthesis have been identified in model plants, but limited information is available for non-model plant species featured with colored leaves. in this study, two pak choi varieties with green or purple leaves were selected to analyze the anthocyanin biosynthesis through rna-seq. | 2017 | 28399809 |
