“…Passion fruit juice is typically acidic: the juice pH range of 2.72-3.11 obtained for both studied seasons was normal and it agreed with the earlier reports by Morton [3] and Araujo et al [7], who found that yellow passion fruit juice pH ranged from 2.06 to 3.00. It was notable that titratable acidity revealed a progressive increase (1.9-4.35) as the manure rate increased in both seasons, similar to what was reported by Nakasone and Paull [2], who showed a range of 2.5-4.0%, although Beal and Farlow [23] reported 3.0-4.0%.…”

“…The variation in these values may probably be attributed to seasons and/or location. Citric acid is the pre-dominant organic acid in yellow passion fruit, accounting for about 83% [3,7].

“…According to Nakasone and Paull [2], and Costa Araujo et al [7], fruit quality consists of several attributes, including physicochemical characteristics, nutritional value, purity, appearance, flavor and consistency. Among other factors, these fruit qualities are associated with the cultivar, the climate, the harvesting time and fertilization [10,11].…”

Impact of poultry manure and harvest season on juice quality of yellow passion fruit (Passiflora edulis var. flavicarpa Deg.) in the sub-humid zone of Nigeria. Abstract-Introduction. The production of high quality fruit juice involves several cultural inputs. Among other factors, fruit quality attributes are influenced by the cultivar, the climate, the harvesting time and soil fertility. Particularly, the soil fertility has a significant effect on the nutritional characteristics of the juice. Good practice as regards fertilization consists of applying rates adapted to plant optimum growth, yield and fruit quality. Materials and methods. Effects of four poultry manure rates [(0, 5, 10 and 15) t•ha-1 ] on the juice quality of passion fruits (Passiflora edulis var. flavicarpa) were evaluated for two cropping years (2005 and 2006). The seedlings of passion fruit vine were field-established in a randomized complete block design, and the manure treatments were replicated four times. Juice quality assessment was performed on fruits picked in December 2005, coinciding with the dry season and low soil moisture recharge, and August 2006, during the wet season and high soil moisture recharge. Results. The results obtained indicated a significant poultry manure effect on all the juice quality parameters studied; the quality of the juice increased gradually as the manure rate increased. Similarly, the season of fruit-picking had a significant effect on the juice quality. As expected, vines that received no manure produced fruits with the poorest juice quality, suggesting unfavorable nutritive conditions within the vines. The concentrations of anti-nutrient factors (tannin, hydrogen cyanide, phytate and calcium oxalate) were low in ripe yellow passion fruits, and insignificant regarding health hazards for consumers of yellow passion fruit. Conclusion. The results obtained showed that the manure rate and the harvest period affected the quality of passion fruit juice. Application of 15 t•ha-1 poultry manure generally gave the best juice quality; similarly, fruits harvested in the first cropping season had better juice quality.

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

2009

View full text Add to dashboard Cite

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.
