“…This increase in the concentration of sugars in the fruit may have been due to the role that K plays in the apoplastic co-transport during the sucrose charge from the mesophile to the phloem, mediated by ATPase enzymes (Le Bot et al, 1994). Other results would confirm the positive effect of a K increase upon the TSS of this species, as has been documented by several authors (Lin, Huang and Wang, 2004;Demiral and Köseoglu, 2005).…”

“…The physiological functions of K in plants are numerous, including enzymatic activation, osmoregulation, and synthesis of carbohydrates, nucleic acids and proteins (Demiral and Köseoglu, 2005). The Ca, in its turn, has important functions in plant nutrition, which range from being a stabilizing element of the cell wall to becoming a secondary messenger in the cytoplasm (Le Bot, Pilbeam and Kirkby, 1994).…”

summaryThe aim of this work was to study the effect of potassium and calcium in combination with nitrogen upon the yield and fruit quality of outdoor-grown melon (Cucumis melo L.). Two experiments were simultaneously performed through the use of two cultivars: 'Honey Dew Green Flesh' (Inodorus group) and 'Sivan' (Charentais group). A completely randomized experimental design was used with nine treatments resulting in a factorial arrangement of 3 x 3 due to the use of three doses of K and three doses of Ca. Doses were administered through fertigation with the injection of the fertilizers into a drip irrigation system, ) was measured as well as fruit quality attributes: firmness (kg); pulp or mesocarp thickness (mm) and rind thickness (mm); and total soluble solids (%). Differences were observed between the two varieties. The application of K showed the greatest effect on the quality and yield of the harvested fruit. However, this effect was not observed with Ca.

“…In a number of studies involving several fruiting crops (e.g. cucumber, mango, and muskmelon) where soil-applied fertilizer K was compared to foliar K applications, the latter approach consistently resulted in improved fruit quality attributes whereas the former approach generally had little or no effects (Demiral and Koseoglu 2005;Lester et al 2005;Lester et al 2006;Jifon and Lester 2009; Table 1). Furthermore, in studies where several fertilizer K salts were evaluated, fruit quality improvements appeared to depend on timing of application as well as fertilizer K formulation.…”

Among the many plant mineral nutrients, potassium (K) stands out as a cation having the strongest influence on quality attributes that determine fruit marketability, consumer preference, and the concentration of critically important human-health associated phytonutrients. However, many plant, soil, and environmental factors often limit adequate uptake of K from the soil in sufficient amounts to satisfy fruit K requirements during development to optimize the aforementioned quality attributes. The objectives of this review are 1) to summarize published study abstracts on the effects of soil and/or foliar K fertilization as well as diverse K forms, on fruit phytonutrient concentrations; and 2) to illustrate the important role of K forms on fruit quality with a case study of Cucumis melo L (muskmelon) fruit produced with optimal soil applied K . The muskmelon studies will compare commercial sources (forms) of K applied to examine seasonal effects (spring vs. autumn) and the number of foliar K applications during fruit development on fruit marketability (maturity, yield, firmness, soluble solids, sugars, relative sweetness), consumer preference attributes (sugar content, sweetness, texture), and phytochemical concentrations (K, ascorbic acid, and β-carotene concentrations). Numerous studies have consistently demonstrated that specific K fertilizer forms, in combination with specific application regimes, can improve fruit quality attributes. Potassium fertilizer forms in order of effectiveness (Glycine (Gly)-complexed K=K 2 SO 4 ≥KCl>no K> KNO 3 ) when applied wet (foliar or hydroponic) vs. dry (soil) were generally superior in improving fruit marketability attributes, along with many humanhealth nutrients. The muskmelon case study demonstrated that two K forms: Gly-complexed K and K 2 SO 4 , combined with a silicone-based surfactant, applied weekly, as a foliar spray, during fruit development, from both autumn and spring-grown plants, had the greatest impact on improving fruit marketability attributes (maturity, yield, firmness, and sugars), as well as fruit quality attributes (human-health bioactive compounds K, ascorbic acid, and β-carotene). Among several foliar applied K salts studied under field conditions so far, salts with relatively low salt indices appeared to have the greatest impacts on fruit quality when applied during the mid-to late-season fruit development periods.

“…As one of the most abundant cations in cells, potassium (K + ) not only contributes to plant growth, development, and fruit quality and yield (Maathuis and Sanders, 1996;Véry and Sentenac, 2003;Demiral and Köseoglu, 2005;Hartz et al, 2005), but it also favorably improves plant tolerance to various abiotic stresses, such as drought (Li et al, 2011;Song and Su, 2013;Song et al, 2014a), salt (Li et al, 2011;Mian et al, 2011;Song et al, 2014b), and cold (Rai et al, 2008). However, studies of K + in relation to plant tolerance to heavy metals have not been undertaken to date.…”
