INFLUENCE OF ABIOTIC DISORDERS ON NUTRITIONAL VALUES OF TOMATO (SOLANUM LYCOPERSICUM)

Susceptibility to abiotic disorders could play a key role in the utilization of landraces of tomato. These races have been abandoned due to non-compatibility to today’s intensive agriculture. As there is dissatisfaction on present varieties and hybrids in the context of flavor and nutritional value, landraces could be a viable alternative for the enhancement of these parameters either “per se” or as breeding background. However, frequent occurrence of abiotic disorders causes yield losses. The hypothesis of the present study is that removal of irregular fruit parts positively influences the nutritional profile of tomato in the context of investigated parameters.In the present study influence of abiotic disorders on total soluble solids (TSS), acid (TA) and lycopene content was investigated on six Hungarian tomato landraces and two commercial varieties. Abiotic disorders occurred were mainly cracking, green shoulder, sunburst and catfacing. Propagation materials were provided by Plant Biodiversity Center Tápiószele. The experiment is supported by Research Institute of Organic Agriculture, ÖMKi. Our results showed that abiotically disordered plant parts have an impact on TSS, TA and lycopene content, however, in case of investigated accessions and varieties the difference was seldom significant. Only in case of TSS a tendency can be experienced, where all samples showed lower results after the removal of abiotically disordered plant parts. In case of TA and lycopene content no tendencies could have been withdrawn

Organic Edunet–Call for a Worldwide Platform in Organic Agriculture

Organic.Edunet (ECP-2006-EDU-410012 Organic.Edunet) aims to facilitate access, usage and exploitation of digital educational content related to Organic Agriculture (OA) and Agroecology. It deploys a multilingual online federation and digital environment of learning repositories, populated with quality content from various content producers. Organic.Edunet focuses on achieving interoperability between the digital collections of OA and Agroecology content of various EU countries. In this way, digital content that can be used to educate European Youth about the benefits of OA and Agroecology, becomes easily accessible, usable and exploitable. As the end of the project approaching the system has been set up and located to content providers preserving the network system. All partners related to education has uploaded all of their learning objects. In order to ensure the sustainability of the portal all partners contribute to affiliated partners’ organization. The project offers a digital and user defined portfolio for them even in regular learning systems or lifelong learning.</jats:p

Antioxidant profile of tomato landraces for fresh consumption

Tomato is one of the most important and frequently consumed vegetable species in Hungary, as well as a significant vitamin source throughout the year. Due to its antioxidant content, tomato consumption is related to the reduced occurrence of cardiovascular diseases and certain cancer types. In our study, four Hungarian tomato accessions [RCAT030275 (Cegléd), RCAT031012 (Veresegyház), RCAT031095 (Cigánd), RCAT054422 (Jánoshalma)] and a commercial cultivar (Hellfrucht) were investigated according to antioxidant capacity [ferric reducing power (FRAP), total phenol content (TPC) and radical scavenging activity (DPPH)], lycopene and ascorbic acid content. A two year (2013-2014) open field trial was carried out in the certified organic area of SZIE Soroksár Experimental and Educational Station. Our results showed that no significant differences were between the landraces and the variety in DPPH values, while TPC values were higher in both years in the landraces, especially in RCAT031095, and RCAT054422. The lycopene content of RCAT031012, RCAT031095 and RCAT054422 was also higher in both years than those of Hellfrucht. The results demonstrate that small-scale production of the investigated landraces could be marketable
