Effect of Grafting and Growing Media on the Chosen Fruit Quality Compounds and Sensory Parameters of Sweet Pepper (Capsicum annuum L.)

Grafting is an effective tool in intensive vegetable growing systems that provides standard quality and yield. In the present study, the effect of two rootstocks (‘Capsifort F1’ and ‘Snooker F1’) on two commercial varieties (‘SV9702 F1’ and ‘Karpex F1’) grown on two media (soil and coconut fibre) was evaluated. During our 2-year study, those instrumental attributes, which have a dominant effect on the chosen chemical components of fruit quality (total soluble solids and titratable acidity) were investigated. Sensory tests were also implemented in order to identify any changes due to the applied technological combinations. Sensory profile analysis was used to identify the descriptive attributes and their perceived intensities. Panellists worked in individual booths with standard lighting, test results were recorded with the Profisens software. In general, it can be concluded that the major instrumental and sensory parameters did not deteriorate as a result of grafting and the application of coconut fibre medium. Some attributes were identified, where the grafted plants on coconut fibre medium showed higher values, namely flesh thickness and shape. Based on our results, grafting and the application of coconut medium is a feasible technological development for growers and agri-business companies

Expression of the Aspergillus bimG gene in Neurospora crassa

In A. nidulans the bimG gene codes for the catalytic subunit of protein phosphatase 1. The wild type bimG gene was transformed into N. crassa and expressed under the direction of the alcA promoter. The heterologous bimG mRNA and protein were detected in the transformants by RT-PCR and Western blotting, respectively. However, the transformation did not result in detectable changes in phenotype. This work demonstrates that the alcA promoter, a conditional gene expression system widely used in both Aspergillus and higher plants, also functions in N. crassa

Application of 1-MCP on apricots at different temperatures and days after harvest

The efficacy of 1-MCP on apricots at different treatment temperatures and days after harvest during 6 weeks of storage at 1 °C was investigated. On the 1st, 3rd, or 5th day after harvest, fruit were treated with 1-MCP at 1 °C for 24 hours. In order to evaluate the effect of temperature, apricots were exposed to 1-MCP at 1, 10, and 20 °C (on the 1st day after harvest). 1-MCP application reduced the ethylene and CO2 production and delayed softening. Fruit treated on the 1st day after harvest presented the highest firmness at the end of the experiment. No significant effect of treatment temperatures on apricot quality was observed. The time period between harvest and 1-MCP application could be delayed until the 5th day after harvest. Results showed that 1-MCP extended the storage life and maintained the overall quality of apricot during storage and shelf-life

Antioxidant, polyphenol and sensory analysis of cherry tomato varieties and landraces

Among vegetables produced both for raw consumption and processing, tomato is one of the most important one in Europe, by production area and by yield as well. In the past years several study dealt with the investigation of the inner content of tomato, with special regards to antioxidant content. In this paper cherry tomato varieties and landraces from conventional and organic production were compared. Besides basic investigations sensory analysis were designed and Antioxidant Capacity (AOC) and Total Phenol Content (TPC) were measured. The aim of the research was to compare varieties and to study the effect of variety and production methods on antioxidant capacity and sensory profiles

A Computing and Detector Simulation Framework for the HIBEAM/NNBAR Experimental Program at the ESS

The HIBEAM/NNBAR program is a proposed two-stage experiment at the European Spallation Source focusing on searches for baryon number violation via processes in which neutrons convert to antineutrons. This paper outlines the computing and detector simulation framework for the HIBEAM/NNBAR program. The simulation is based on predictions of neutron flux and neutronics together with signal and background generation. A range of diverse simulation packages are incorporated, including Monte Carlo transport codes, neutron ray-tracing simulation packages, and detector simulation software. The common simulation package in which these elements are interfaced together is discussed. Data management plans and triggers are also described.Comment: Contribution to CHEP2021.

Effect of boron fertilisation on the flavour of carrots - Applicability of organoleptic analyses to carrots

Foliar boron fertilisation has had positive influence only on carotene content. Results were evaluated with chemical analyses and sensory tests. It has been observed that sensory tests are able to detect bitter flavour and also to measure its interaction with sweet flavour. Sensory tests for evaluation are generally used in the EU, also in the case of fruits and vegetables. With the aid of students and staff having received training and acquired practice, our University has the possibility to complete chemical analyses in such a way that satisfies modern demands, as well as facilitating the sale of the products on foreign markets
