“…This result differs from those found by other authors, as high levels of Ca affect the absorption of Mg, and vice versa (Lima et al 2018;Bell 2022). This inhibition is related to the similarity in chemical properties, such as valence and mobility, thus providing competition for sites of adsorption in the soil and absorption by roots (Guimarães Júnior et al 2013;Coskun and White 2022). Considering that high Ca levels reduce Mg absorption, and vice versa, and that in this study the soil of the experimental area had low levels of these nutrients and low pH, the effect of reduction was not verified (Table 1).…”

“…Considering that K is absorbed by many species in amounts higher than those necessary for vegetative metabolism ("luxury consumption"), in this condition plants may have influenced the absorption of cations, as long as they are not competing for the same carrier site (Coskun and White 2022). Thus, it is assumed that the foliar K contents positively influenced the Zn and Cu contents.…”

“…In the plant, nutritional balance is a very complex and dynamic mechanism due to interactions between nutrients. This is because nutrients behave in different ways, and they can also have different pathways or locations for absorption, which may be exclusive pathways or shared by more than one nutrient (Coskun and White 2022). Also, according to the authors, the interaction between nutrients can also occur due to the difference in ion charges, which may compromise or facilitate the absorption of the other.…”

“…Non-competitive inhibition is characterized when the absorption sites are different for each element. Finally, synergism, which occurs when the presence of one element favors the absorption of another element, provides a beneficial effect for the plant (Coskun and White 2022).…”

In plants, several chemical elements are found in different concentrations and formulations. Some of these elements influence each other, either through positive stimulation or inhibition. This study evaluated the correlation between nutrient contents and production components of Jatropha (Jatropha curcas L.). The experiment was conducted at the Federal University of Viçosa-MG, Brazil. A randomized block design with four replications was used. The treatments consisted of six Jatropha clones transplanted 4.5 years ago, from the municipalities of Janaúba and Bomfim, in Minas Gerais, Brazil. Yield was determined by harvesting the ripe and dried fruits, and the oil and protein contents in the grains were obtained by nuclear magnetic resonance. To determine nutrient contents, leaves were collected when the plants were in flowering, with yellow fruits and when the fruits were dry. There was a significant and negative association between grain yield and Mg content. Regarding foliar nutrient contents, the positive (r) significant correlations were between the following pairs: (N and S, r=0.554); (N and Cu, r=0.460); (P and Ca, r=0.420); (K and Zn, r=0.511); (K and Cu, r=0.506); (Ca and Mg, r=0.603); (Zn and Fe, r=0.662); (Zn and Mn, r=0.795); (Zn and Cu, r=0.574); (Fe and Mn, r=0.528) and (Mn and Cu, r=0.479); and the negative ones were between: (K and Ca, r=-0.596); (K and Mg, r=-0.673); (Mg and Cu, r=-0.506). Therefore, it was possible to prove the existence of nutritional interaction between some elements, as well as the effects on grain yields. This research will serve as a basis for studies to recommend fertilizer doses, plant improvement through nutritional efficiency, and studies in the area of biochemistry.

“…Active transport involves the transportation of Pb ions into the root cells by specialized transport proteins, such as ion channels or pumps. 72 The foliar absorption of Pb could take place by two means i.e. either cuticular penetration or by stomatal uptake, wherein the former Pb ions are actively transported into the root cells by specialized transport proteins, such as ion channels or pumps.…”
