Abstract The use of natural materials that is eco-friendly on leather as vegetable tannins has become a matter of significant importance, as a result of increased environmental awareness to prevent some hazardous synthetic tannin. Therefore, this study investigated that the potential of the extracted tannin from Sodom apple (Solanum Incanum) fruit for its effectiveness as vegetable tanning agent on goatskins. It was extracted with distilled water, methanol, petroleum ether and ethanol by using Soxhlet extraction method. Although the amount of material extracted was significant in all extracting solvents, water was a more efficient solvent (extraction yield of 16.71%) than the others. The qualitative analysis and structural characterization of the extracts were done using thin layer chromatography (TLC), Ultraviolet (UV) spectrometer and Fourier Transformer Infrared (FT-IR) spectrometer. The analysis confirmed that the presence of condensed tannins in the extract, which usually used for the application of tanning process in leather manufacturing industry. On other hand, the Quantitative Analysis of Sodom apple fruit extract was conducted by evaluating its moisture content (7.59%), total soluble solids (21.45%), tannin content (12.13%) and non-tannin contents (9.32%). The Scanning Electron Microscope (SEM) was carried out to study the effect of the tannin system on the structural and morphological characteristics of the tanned leathers. Similarly, the organoleptic and strength properties of the tanned leathers were evaluated in comparison with the control ones. Finally, the pollution loads of tanning liquors in Sodom apple tanning significantly reduced as compared with the control (mimosa). Thus, the results in this study showed that the manufacture of leather based on Sodom apple fruit extract found to be a cleaner alterative and promising pathway for tanning goatskins.

Sodom apple (Solanum incanum L.) fruit extracts were tested for their potential to manage root knot disease caused by Meloidogyne spp. in chilli (Capsicum annuum L.). The effect of sodom apple fruit extracts at different concentrations on the plant height, leaf number, stem diameter, number of galls, and nitrogen and phosphorous levels in chilli infected with root knot nematodes was evaluated. The efficacy of sodom apple fruit extracts against the root knot nematodes was tested under glasshouse and field conditions. All treatment effects were determined by one-way ANOVA using SAS program (Version 9.3). Evaluation after treatment of plants with sodom apple fruit extracts showed that there was a significant difference (P=0.05) in plant heights, number of galls, leaf number, and nitrogen levels in chilli. In the field experiment, the highest mean heights were recorded in the 100% treatment (T1) during the first and third reading. Chilli plants that were treated with the sodom apple fruit extract had a significantly high number of leaves. In the greenhouse experiment, the positive control (T6) had the highest mean heights followed by the 50% treatment (T2). Our research results showed that sodom apple fruit extracts have nematicidal compounds with a potential to be used in the management of chilli root knot nematodes.

Bull's Eye

Apple fruit in Chile are primarily produced for export to Asia, Europe, and the United States, which typically requires 15 to 40 days of maritime transportation. Therefore, Chilean apple production must fulfill the sanitization requirements imposed by the receiving countries. Under these circumstances, it was important to clarify the etiology of bull's eye rot that can severely affect ‘Cripps Pink’ apple and other late-harvest cultivars in Chile. Based on morphological characteristics and the partial sequence analysis of the internal transcribed spacer sequences and β-tubulin genes, Neofabraea alba was identified as the causal agent of the bull's eye rot of Chilean apple. These results were further corroborated using species-specific primers. The incidence of bull's eye rot varied considerably; for instance, in 2009, 0.0 to 58.7% in 38 Cripps Pink orchards surveyed in the relatively arid and humid apple-growing areas of Chile, respectively. There was no evidence for the presence of N. malicorticis or N. perennans, which are commonly identified as causal agents of bull's eye rot in other apple-producing countries. Altogether, these data suggest that N. alba might represent the predominant and possibly the only cause of bull's-eye rot of Chilean apple.

AbstractSeveral species of the genus Fusarium can cause apple fruit to rot while stored. Since Fusarium taxonomy is very complex and has constantly been revised and updated over the last years, the aim of this study was to identify Fusarium species from rotten apples, based on combined morphological characteristics and molecular data.We identified 32 Fusarium isolates from rotten apple fruit of cultivars Golden Delicious, Jonagold, Idared, and Pink Lady, stored in Ultra Low Oxygen (ULO) conditions. Fusarium rot was detected in 9.4 % to 33.2 % of naturally infected apples, depending on the cultivar. The symptoms were similar in all four cultivars: a soft circular brown necrosis of different extent, with or without visible sporulation. Fusarium species were identified by the morphology of cultures grown on potato-dextrose agar (PDA) and carnation leaf agar (CLA). Twenty one isolates were identified as Fusarium avenaceum and confirmed as such with polymerase chain reaction (PCR) using specific primer pair FA-ITSF and FA-ITSR. F. pseudograminearum,F. semitectum, F. crookwellense, and F. compactum were identified by morphological characteristics. F.avenaceum can produce several mycotoxins and its dominance in Fusarium rot points to the risk of mycotoxin contamination of apple fruit juices and other products for human consumption. Pathogenicity tests showed typical symptoms of Fusarium rot in most of the inoculated wounded apple fruits. In this respect Fusarium avenaceum, as the dominant cause of Fusarium rot in stored apple fruits is a typical wound parasite.

This study was aimed at observing the effect of the grafting of tomato plants on morphological (vegetative growth), production and nutritive characteristics (quantity and quality of production). For this purpose, the ‘Lorely F1’ cultivar was used as a scion grafted onto the ‘Beaufort’ rootstock. Plants were cultivated with a stem and two stems. The observations collected in this study were concerned with the characteristics of plant growth. The studied morphological characteristics were plant height, stem diameter and number of leaves, and the studied production characteristics were the characteristics of fructification and productivity (the average number of fruit per plant, the average weight of the fruit, production per plant). Particular attention was paid to the nutritional characteristics of the fruit, to the fruit quality (total soluble solids, total sugar, acidity, vitamin C, antioxidant activity (by the Trolox method) and the contents of lycopene and beta-carotene). The results showed that grafting positively influenced the growth and production characteristics. Grafting of tomato plants had an appreciable effect on the vegetative growth of the variant 2-grafted tomatoes with a stem. The best option in terms of productivity and production was the variant 3-grafted tomatoes with two stems, which yielded 9.2 kg per plant. Fruit quality was not improved in any of the grafted variants.

Abstract: The objective of this work was to characterize the productive and qualitative performances of 11 clones of 'Bordô' grape (Vitis labrusca) destined to wine and juice production, in the region of Vale do Rio do Peixe, in the state of Santa Catarina, Brazil. The experiment was carried out in the 2011, 2012, 2014, and 2015 crop seasons. The analyzed yield components were: number of clusters per vine, yield, cluster weight, accumulated yield, and alternate bearing index. The analyzed morphological characteristics of clusters were: number of berries per cluster, berry diameter, cluster compactness index, and cluster length. In order to assess grape quality, the following parameters were analyzed: soluble solids (SS), pH, titratable acidity (TA), SS/TA ratio, total anthocyanins, and total polyphenols. The 'Bordô' grape clones 13 and 16 ('Paco' and 'Bocaina') are the most suitable ones for cultivation in the wine producing region of Vale do Rio do Peixe, as they show the highest yields, production stability, and grapes with adequate quality for wine and juice elaboration.

Beetroot consumption based on pickled beets generally in Hungary which is due to the higher yield from second crop harvested in autumn and processed by manufacturing industry. Researches of the past years confirmed its favourable nutritional-physiological effects on human body so demands, as for fresh salad, also increased. The trial aimed at testing the interaction of varieties on quality parameters and in the same time suggestions are made how to use different varieties of beetroot according to its quality. Morphological and sensory evaluations were examined on 10 varieties of beetroot harvested in autumn. The regular spherical shape can reduce the refining loss during the processing of beetroot which is beneficial for the manufacturing industry. In our trial the root shape of Libero, Mona Lisa and Rubin varieties approached most the regular spherical shape (diameter/length – 1.0) which is favoured by not only processing industry but also fresh market. The highest red pigment content (betanin) was observed in Mona Lisa, Akela and Cylindra (34.58–47.66 mg/100 g). A similar trend could be observed in yellow pigments (vulgaxanthins) which proves the close correlation between the quantities of the two pigments (r=0.898). Highest total polyphenol (77.13–83.37 mg GAE/100g) and flavonoid (21.73–22.73 mg CE/100g) contents were detected in Akela, Mona Lisa and Bonel. These varieties are favourable for fresh salad and they can satisfy processing requirements also. Highest water soluble solids content was found in Akela (7.15%). In our conditions nitrate (NO3-N) values below 900 mg/kg were examined in all of the varieties which is favourable in the case of beetroot.

Optical microscopy and dielectric relaxation spectroscopy (DRS) were used to study the structure of dynamically vulcanised mixes based on polypropylene, ethylenepropylenediene rubber, and copolymers of ethylene and vinyl acetate (Levapren 400, 600, 700). For the microscopic investigations, we used a complex consisting of a Leica DM-2500 optical microscope, a DFC 420C cooling chamber, and a special computer desk. DRS data were obtained on a BDS 89 instrument (NovoControl) at temperatures ranging from −150 to +100°C at a heating rate of 2°C/min and a frequency of 110 Hz. The influence of the content of Levapren and the proportion of vinyl acetate in its composition on the morphology and processing properties of olefinic thermoplastic vulcanisates (TPVs) was investigated. The combination of the discovered changes in the fine structure and DRS data indicate the preferential interaction of Levapren with the rubber component. The evolution of the morphology of the TPVs with increase in the volume fraction of vinyl acetate is not monotonic, which is consistent with the nature of change in the physicomechanical properties of the TPVs. Combined analysis of the morphological characteristics and processing properties of TPVs showed that, to achieve high values of the deformation and strength properties, a uniform distribution and high polydispersity of the ingredients are necessary. Increase in the elastic properties of the material is ensured by modification of the polypropylene phase to form fibrillar structures, while the flow of TPEs that is necessary for processing is facilitated by modification of the rubber phase.
