The persimmon fruit is a good source of ascorbic acids, sugars, carotenoids, organic acids, vitamins, minerals, phenolic compounds and dietary fiber (Del-Bubba et al., 2009; Veberic et al., 2010). Being rich in ascorbic acid and phenolic compounds, the persimmon fruit may protect against oxidative stress (Scalbert and Williamson, 2000; Suzuki et al., 2005). The Persimmon fruit rapidly deteriorates during storage mainly due moisture loss and pathological disorders (Gorinstein et al., 2001). Pre and postharvest infections causing decay and moisture loss are the major causes of quality deterioration during storage (Terry and Joyce, 2004; Misir et al., 2014). Thus, delaying softening and disease control are the primary techniques to extend the storage life of persimmon fruit (Khademi, 2012). Attempts have been made to increase the storage life of persimmon fruit by the application of chemicals (Zheng et al., 2006; Bagheri et al., 2015). However, the use of chemicals to increase the postharvest life of fruits has limited scope due to potential risks to human health (Asghari et al., 2013). Recently edible coatings have developed for preserving the horticultural commodities and improve the appearance of the fruit (Mandal et al., 2009). Edible Abstract | Storage durations and Aloe vera gel concentrations significantly decreased the loss of persimmon fruit quality during storage at room temperature. Storage at room temperature (26±2 °C) resulted in significant decline in fruit firmness, percent acidity, and ascorbic acid content with a concomitant increase in total soluble solids (TSS), organoleptic quality (Taste) score and decay incidence. Coating of persimmon fruits with 30% Aloe vera gel retarded the storage related changes and retained high fruit firmness, acidity and ascorbic acid as well as lower total soluble solids and decay incidence than control fruits. In control fruits (0 days storage + Distilled water treatment), the fruit firmness (3.33 kg cm-2), acidity (0.29%), and ascorbic acid content (46.25 mg/100g) decreased to 0.06%, 16.47 mg/100g and 0.56 kg cm-2 , respectively, and the TSS (12.45%) and decay incidence (12.55%) increased to 37.56 and 100% respectively during 35 days storage at room temperature. By contrast, fruit treated with 30% Aloe vera gel retained high fruit firmness (2.46 kg cm-2), acidity (0.19%), ascorbic acid content (29.76 mg/100g) as well as lower TSS (20.2%) and decay incidence (43.85%) after 35 days storage at room temperature.

On the basis of various qualitative traits, 18 superior walnut genotypes were selected along with two exotic varieties. Every single band was considered as a single locus/allele for all the genetic analyses. The 18 indigenous genotypes showed various levels of genetic polymorphism for the loci detected by using primers GLA-05 and GLA-10. The loci were scored as present (1) and absent (0). Bivariate 1-0 data matrix was used to estimate genetic distances (GD) and for construction of Phylogenetic tree based on cluster analysis. Maximum genetic distance (100%) was observed between Payne and Sw-58 and Payne and Serr, closely followed by 94% dissimilarity between Payne and Dr-67. Based on the data presented as dendrogram, the walnut genotypes were classified in to four major groups. The maximum numbers (13) of genotypes fall in group-I. Sw-58 was the only genotypes in group-IV and the most distinct from others. Classification of wild genotypes will help in breeding as well as vegetative propagation of walnut trees.

Blood Red was conducted at Nuclear Institute for Food and Agriculture (NIFA), Peshawar during 2003-2004. The fruits of sweet orange were stored for 75 days at room temperature in different unipacking materials i.e. polyethylene, cellophane, polyethylene green, wax paper, kraft paper and news paper. It was found that taste and visual quality significantly decreased with 45 days storage at room temperature. Increasing storage duration resulted in significant increase in weight loss, total soluble solids and TSS/Acid ratio, while Ascorbic acid content and percent acidity decreased with extension in storage duration. Cellophane and polyethylene uni-packing resulted in significant retention of taste and visual quality over 45 days storage, with minimum weight loss of 1.18% and 1.33% respectively, and high ascorbic acid content (60.45 mg/100 ml as compared to 44.86 mg/100 ml) in control over 75 days storage at room temperature. There was a slight decrease in percent acidity in polyethylene (1.34%) and cellophane (1.31%) uni-packing as compared to 1.68% in control. Total soluble solids increased with increase in storage duration with maximum increase in control and news paper uni-packing (12.73% each), which was significantly higher than Cellophane (11.60%) and polyethylene (11.73%) after 75 days. Similarly TSS/acid ratio also increased with increasing storage with maximum increase in control (12.18) but was significantly lower in polyethylene green (7.61), cellophane (7.64) and polyethylene (8.95) after 75 days storage.

Changes in several physiological attributes greatly affect its quality and market value. The current study was designed to assess the effect of chitosan solution (an edible coating material that can improve postharvest performance) on physico-chemical attributes of persimmon fruit during storage. Persimmon fruits were harvested, cleaned and then dipped in various chitosan concentrations (1%, 2% and 3%) for 5, 10 and 15 min. The treated fruits were stored at 25–29°C, 55–70% RH for 28 days. Results indicated that fruits coated with 3% chitosan solution had maximum volume, firmness, ascorbic acid, titratable acidity and minimum juice, TSS, pH, TSS/acid ratio, decay incidence and weight loss. Similarly, the performance was better in fruits dipped for 15 min. It was concluded that persimmon fruits dipped in 3% chitosan solution for 15 min could improve its postharvest performance when stored under ambient condition.

Blood Red was conducted at Nuclear Institute for Food and Agriculture (NIFA), Peshawar during 2003-2004. The fruits of sweet orange were stored for 75 days at room temperature in different unipacking materials i.e. polyethylene, cellophane, polyethylene green, wax paper, kraft paper and news paper. It was found that taste and visual quality significantly decreased with 45 days storage at room temperature. Increasing storage duration resulted in significant increase in weight loss, total soluble solids and TSS/Acid ratio, while Ascorbic acid content and percent acidity decreased with extension in storage duration. Cellophane and polyethylene uni-packing resulted in significant retention of taste and visual quality over 45 days storage, with minimum weight loss of 1.18% and 1.33% respectively, and high ascorbic acid content (60.45 mg/100 ml as compared to 44.86 mg/100 ml) in control over 75 days storage at room temperature. There was a slight decrease in percent acidity in polyethylene (1.34%) and cellophane (1.31%) uni-packing as compared to 1.68% in control. Total soluble solids increased with increase in storage duration with maximum increase in control and news paper uni-packing (12.73% each), which was significantly higher than Cellophane (11.60%) and polyethylene (11.73%) after 75 days. Similarly TSS/acid ratio also increased with increasing storage with maximum increase in control (12.18) but was significantly lower in polyethylene green (7.61), cellophane (7.64) and polyethylene (8.95) after 75 days storage.

Changes in several physiological attributes greatly affect its quality and market value. The current study was designed to assess the effect of chitosan solution (an edible coating material that can improve postharvest performance) on physico-chemical attributes of persimmon fruit during storage. Persimmon fruits were harvested, cleaned and then dipped in various chitosan concentrations (1%, 2% and 3%) for 5, 10 and 15 min. The treated fruits were stored at 25–29°C, 55–70% RH for 28 days. Results indicated that fruits coated with 3% chitosan solution had maximum volume, firmness, ascorbic acid, titratable acidity and minimum juice, TSS, pH, TSS/acid ratio, decay incidence and weight loss. Similarly, the performance was better in fruits dipped for 15 min. It was concluded that persimmon fruits dipped in 3% chitosan solution for 15 min could improve its postharvest performance when stored under ambient condition.

The plants used in this investigation are rich in alkaloids, flavonoids, steroids, terpenoids, protein, amino acids, carbohydrate, quninones, phenols and tannins. The formation of nanoparticles were confirmed by UV/Visible spectroscopy, peaks at 423nm for Ajuga parviflora Benth and 408nm for Digera muricata. The morphology of the silver nanoparticles was established through state of the art spectroscopic tools. SEM analysis reveals average size of AgNPs 18 nm for Digera muricata and 22 nm for Ajuga parviflora Benth respectively while transmission electron microscopy confirms that AgNPs are spherical in shape. The synthesized nanoparticles were subjected to Escherichia coli, Staphylococcus aureus, Salmonella typhimurium and Pseudomonas aeruginosa. The results suggest that the silver nanoparti...
