“…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).…”

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.

“…Hartz et al (2001Hartz et al ( , 2005 attributed the absence of any response of fruit SSC to other overriding factors, such as cultivar and irrigation management, which potentially masked any K effects. Lin et al (2004) found that supplemental K fertilization of melon in soilless culture increased fruit sucrose content but had no effect on fruit fructose and glucose concentrations. However, in the Lester et al, (2006) study, netted muskmelon fruit sucrose, glucose and fructose levels were increased by supplemental foliar K fertilization.…”

“…(Ache et al 2001) provided evidence for faba bean (Vicia faba L.) indicating that K + channels are involved in sugar unloading. Potassium-induced increases in fruit sugar levels have also been reported in hydroponically grown muskmelon plants (Lin et al 2004) however, the mechanism for this effect was also unclear. Although a threshold tissue K concentration for attaining optimum fruit sugar levels has not been established, our melon data (Lester et al 2005 and2006;Jifon and Lester 2009) provide additional evidence that fruit sugar concentrations can be increased through supplemental foliar K sprays.…”

Impact of potassium nutrition on postharvest fruit quality: Melon (Cucumis melo L) case study

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.

“…A não aceitação do fruto sob deficiência de K, provavelmente, tenha sido devida ao menor valor de sólidos solúveis totais encontrados nos frutos. Segundo Lin et al (2004) e Shalit et al (2000), há uma correlação positiva entre a concentração total de açúcar e o aroma dos frutos.…”

A comercialização do abacaxi vem expandindo-se no mercado mundial principalmente por suas apreciáveis características de sabor, aroma e cor. A nutrição mineral da planta exerce uma influência acentuada na composição química do abacaxi. A inexistência de informações sobre a influência da deficiência nutricional na qualidade dos frutos do abacaxizeiro 'Imperial' motivou a realização de um experimento em casa de vegetação da Universidade Estadual do Norte Fluminense, em Campos dos Goytacazes-RJ, no período de 2003 a 2005, para avaliar os efeitos das deficiências de macronutrientes e de boro na composição fisico-química e na qualidade sensorial dos frutos dessa cultivar. A unidade experimental constou de um vaso de plástico com 14 L de areia purificada e uma muda de abacaxizeiro. Foram utilizados os seguintes tratamentos: completo, - N, - P, - K, - Ca, - Mg, - S e - B, aplicados sob a forma de soluções nutritivas, em blocos casualizados completos, com seis repetições. As seguintes características foram obtidas nos frutos: firmeza, teor de suco, AT, SST, SST/AT, vitamina C, pH, coloração e a análise sensorial da polpa. As deficiências de N e de K aumentaram a firmeza da polpa, mas a de S a diminuiu. As deficiências de N e S aumentaram a AT e o teor de Vitamina C, mas diminuíram SST/AT, a coloração da polpa e o pH. A deficiência de K reduziu os SSTs e a de Ca e de S os aumentou. As deficiências de N e K reduziram a aceitação sensorial dos frutos. As deficiências de P, Mg e B não alteraram as propriedades sensoriais do abacaxi.
