The aim of present study was to evaluate the variation in uptake of elements (As, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb and Zn) by different varieties of Sorghum bicolor L., plants grown in soil amended with untreated industrial waste water sewage sludge (SUIS), on same experimental plots. The power of chemometrics was also used in exploring the potential natural and/or anthropogenic sources responsible for elemental contents in different varieties of sorghum. Hierarchical cluster analysis was used to explore the different variety of sorghum grouping according to corresponding their SUIS samples as additional information to the output obtained by principal component analysis. Significant genotypic variation was detected in the fourteen elements concentrations in sorghum grains, indicating the possibility to reduce the concentration of toxic elements in grains through breeding approach. It was observed that high tolerance limit of toxic elements was observed in sorghum variety PARC-SV-1.
本研究的目的是评估在同一试验地块上，用未经处理的工业废水污泥（SUIS）改良土壤种植的不同品种双色高粱植株对元素（砷、钙、镉、钴、铬、铜、铁、钾、镁、锰、钠、镍、铅和锌）吸收的差异。化学计量学方法还用于探究造成不同高粱品种元素含量的潜在自然和/或人为来源。采用层次聚类分析，根据相应的SUIS样本探索高粱的不同品种分组，作为主成分分析所得结果的补充信息。在高粱籽粒的14种元素浓度中检测到显著的基因型变异，表明通过育种方法有可能降低籽粒中有毒元素的浓度。观察到高粱品种PARC-SV-1对有毒元素的耐受极限较高。
