The present work aimed to analyze the mineral nutrition of Physalis angulata L. under stress by aluminum in the nutrient solution. The treatments consisted of five different concentrations of aluminum in the nutrient solution (0, 0.04, 0.08, 0.12, and 0.16 mmol L-1) in the AlCl3 form. The plants were exposed to Al for 30 days. Subsequently, nutritional and aluminum analyses were performed on plant tissue. The data were submitted to analysis of variance (p < 0.05), and, in case of significance, the regression study was performed as well as hierarchical cluster analysis (HCA) and principal component analysis (PCA) were used. The formation of four groups occurred, where we can observe the similarity and differences in the treatments between them. The separation of the treatments into groups reflected the heterogeneity of the treatments about the aluminum levels in the nutrient solution, evidencing its phytotoxicity level in Physalis angulata plants. Among the analyzed variables, P, K, Ca, Mg, Fe, Mo, and Zn were the most influential ones demonstrated by principal component analysis (PCA). The stress of 0.16 mmol L-1 of Al increased the phosphorus contents in the stems and roots and the potassium, copper, and molybdenum contents in all parts of the plants. In contrast, Al reduced the levels of calcium, magnesium, iron, and zinc in P. angulata plants. Iron being the micronutrient that showed the largest reduction, followed by zinc in the leaves. The highest levels of aluminum were found in the roots.

探索性分析评估由于酸浆中铝的存在而产生的应力，并通过微波诱导等离子体发射光谱法（MIP OES）测定多元素。

本工作旨在分析营养液中铝胁迫下酸浆的矿物质营养。处理包括五种不同浓度的AlCl3形式的营养液中的铝浓度（0、0.04、0.08、0.12和0.16 mmol L-1）。将植物暴露于Al 30天。随后，对植物组织进行了营养和铝分析。将数据提交给方差分析（p <0.05），并且在显着性的情况下，进行回归研究，并使用层次聚类分析（HCA）和主成分分析（PCA）。发生了四个组的形成，在这里我们可以观察到它们之间处理的相似性和差异。将处理分为几类反映了营养液中铝含量的处理异质性，证明了其在酸浆中的植物毒性水平。在分析变量中，P，K，Ca，Mg，Fe，Mo和Zn是最有影响的变量，主成分分析（PCA）证明了这一点。0.16 mmol L-1的Al胁迫增加了植物根和茎中的磷含量以及植物各个部位的钾，铜和钼含量。相比之下，Al降低了Angulata辣椒植物中钙，镁，铁和锌的含量。铁是减少量最大的微量元素，其次是锌。根中发现铝含量最高。证明其在酸浆植物中具有植物毒性水平。在分析变量中，P，K，Ca，Mg，Fe，Mo和Zn是最有影响的变量，主成分分析（PCA）证明了这一点。0.16 mmol L-1的Al胁迫增加了植物根和茎中的磷含量以及植物各个部位的钾，铜和钼含量。相比之下，Al降低了Angulata辣椒植物中钙，镁，铁和锌的含量。铁是减少量最大的微量元素，其次是锌。根中发现铝含量最高。证明其在酸浆植物中具有植物毒性水平。在分析变量中，P，K，Ca，Mg，Fe，Mo和Zn是最有影响的变量，主成分分析（PCA）证明了这一点。0.16 mmol L-1的Al胁迫增加了植物根和茎中的磷含量以及植物各个部位的钾，铜和钼含量。相比之下，Al降低了Angulata辣椒植物中钙，镁，铁和锌的含量。铁是减少量最大的微量元素，其次是锌。根中发现铝含量最高。16 mmol L-1的Al增加了茎和根中磷的含量，并增加了植物各个部位的钾，铜和钼的含量。相比之下，Al降低了Angulata辣椒植物中钙，镁，铁和锌的含量。铁是减少量最大的微量元素，其次是锌。根中发现铝含量最高。16 mmol L-1的Al增加了茎和根中磷的含量，并增加了植物各个部位的钾，铜和钼的含量。相比之下，Al降低了Angulata辣椒植物中钙，镁，铁和锌的含量。铁是减少量最大的微量元素，其次是锌。根中发现铝含量最高。
