Unravelling the Impact of Essential Mineral Nutrients on Active Constituents of Selected Medicinal and Aromatic Plants

Sweet Basil Functional Quality as Shaped by Genotype and Macronutrient Concentration Reciprocal Action

“…As observed by Nurzyńska-Wierdak and Borowski [ 55 ], the content of this relevant aromatic molecule especially in Italiano Classico was negatively affected by the increased presence of the macrocations, whereas for Eleonora, the use of more concentrated nutrient solutions determined a linear increase of α-bergamotene. The greater biosynthesis of this sesquiterpene typical of sweet basil [ 56 ] could be related to the greater availability of potassium, which as always observed by Nurzyńska-Wierdak and Borowski [ 55 ], and Singh et al [ 57 ] determined in Ocimum basilicum L. a greater production of aromatic molecules belonging to this chemical class.…”

“…The growing interest in this aromatic plant beyond the culinary field is mainly attributed to the high presence of a multitude of phenolic compounds considered as powerful antioxidants [ 9 , 58 , 59 , 60 ]. Phenolic compounds are secondary metabolites produced by plants through the shikimate pathway [ 61 ] and facilitate adaptation of the plant to the surrounding environment [ 57 ]. The content of phenolic composition, as shown by our results, is strongly influenced by the genetic aspect [ 58 , 62 , 63 ].…”

Physiological and Agronomic Implications of Foliar Potassium Application on Sunflower Productivity in Calcareous Soils

“…It is generally known K has the greatest impact on the growth and development parameters of sunflowers (Akram et al, 2009;Raza et al, 2018). Although K is not a component of any plant structures or functional molecules, it is engaged in a number of physiological and biochemical processes essential for robust, healthy crop growth and viable yields (Marschner, 1995;Singh et al, 2017). K is involved in the transport systems in plants that allow materials produced by photosynthesis in the leaf to be transported to other areas of the plant for growth, seed production, and oil deposition (Singh et al, 2017).…”

K also plays a role in stress tolerance, turgor maintenance, photophosphorylation, enzyme activation, stomatal regulation of transpiration and photosynthesis, photophosphorylation, and transport of photoassimilates (Singh et al, 2017).…”

Potassium plays an important role in numerous processes crucial to sunflower cultivation, including osmotic regulation and photosynthesis translocation (Santos et al, 2023).…”
