The survey was conducted on a total of 100 non-labelled samples of feed and feed mixture containing maize, soybean and rapeseed, originating from countries with different legislation systems. Screening of all samples was performed using primers for Cauliflower Mosaic Virus 35S (CaMV35S) promoter, primers for the Agrobacterium tumefaciens nopaline s...

The objective of this work was to evaluate the genetic variation of trypsin inhibitor in cultivated (Glycine max L.) and wild (Glycine sofa Siebold & Zucc.) soybean varieties. Genetic variations of the Kunitz trypsin inhibitor, represented by a 21-kD protein (KTI), and of the Bowman-Birk trypsin chymotrypsin inhibitor (BBI) were evaluated in cultiv...

In order to detect presence and quantity of Roundup Ready (RR) soybean in crude oil extracted from soybean seed with a different percentage of GMO seed two extraction methods were used, CTAB and DNeasy Plant Mini Kit. The amplifications of lectin gene, used to check the presence of soybean DNA, were not achieved in all CTAB extracts of DNA, while c...

The concept of sustainability applied to agriculture has developed mainly as a result of growing awareness of negative impacts of intensive agriculture production systems on the environment and the quality of life. Intensive agriculture systems are based on genetically uniform crops which can be susceptible to various diseases and insect pests. Gen...

Background: This study was carried out for an understanding of the antioxidant mechanisms of field pea varieties under osmotic stress conditions caused by a lack of water. The activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APx) and glutathione reductase (GR) were examined and analyzed. Th...

Seed deterioration is an unavoidable process to which seeds of oilseed plant species such as sunflower are especially sensitive. This study aimed to determine whether different invigoration techniques can improve the attributes of germination in sunflower and alleviate the effects of seed ageing. Both aged and non-aged seeds were subjected to invig...

Legumes represent a valuable source of proteins in human and animal nutrition, as well as of different nutrients. Also, they enable diversification of agroecosystems and can be considered climate smart crops. Therefore, they are gaining importance in both developed and developing countries. The most important, and often limiting factor in legume pr...

Germination and seedling growth of seven genotypes of field pea (Pisum sativum L.) were studied in PEG-6000 solution having osmotic potentials -0.1 and -0.2 MPa. A study was undertaken to evaluate the influence of different osmotic potentials (MPa) on seed germination percentage (GP) and mean germination time (MGT). Results show that the percentage...

Seed vitality and vigour are the two most common parameters related to seed quality. It is crucial to have reliable methods and tests for seed quality and seed vigour testing. The standard germination test can be used to predict field emergence, but laboratory seed testing conditions are often in conflict with field conditions. Validated tests for...

Field peas are mostly used for animal nutrition in the Balkan region and in the countries of the former USSR, while in the countries of Western Europe, Canada, the USA and the Middle East they are mostly used for human nutrition. Over three years (2010–2012), the yield and grain yield components of the most widespread field pea varieties were exami...

Proizvodnja krompira u svetu značajno je ugožena delovanjem fitopatogenih bakterija, te godišnji gubici prinosa poprimaju sve veće razmere. Među deset ekonomski najznačajnijih fitopatogenih bakterija koje smanjuju prinos i kvalitet poljoprivrednih kultura ističu se vrste rodova Pectobacterium i Dickeya – prouzrokovači crne truleži prizemnog dela st...

The aim of this work was to estimate the trypsin inhibitor activity (TIA) in seeds of cultivated pea varieties, wild varieties and selected crosses between varieties from the first group and wild pea varieties and to study the variation in genes coding trypsin inhibitors. Mean TIA in field pea varieties ranged from 3.12 TIU/mg of sample in field pe...

Trypsin inhibitors could limit utilization of legumes in human nutrition, but they could also have beneficial health effects. The objective of this study was to measure trypsin inhibitor activity (TIA) of different legumes using microtiter plate method and to identify factors that contribute to uncertainty of TIA measurement. TIA measurements were...

The aim of this study is to assess DNA degradation, DNA amplification, and GMO quantity during tofu production. Soybean seeds were spiked with Roundup Ready® soybeans (RRS) at 0.9, 2, 3 and 5 % (by mass), to assess the level of RSS that would be of practical interest for threshold labelling. Real-time polymerase chain reaction (PCR) was more effect...

This work considers the results obtained by testing the parameters of antioxidant status in leaves and roots of oilseed rape at different growth stages (phase I: formation of leaf rosettes and preparing for winter hibernation; phase II: after the winter hibernation; phase III: flowering) grown in semicontrolled field conditions on different soil ty...

Protease inhibitor activity is frequently measured in legume seeds as protease inhibitors are thought to have anti-nutritional as well as anti-carcinogenic properties. Trypsin inhibitor activity (TIA) can be measured using different methods. The microtiter plate method is very convenient and routinely used; therefore, in this study, we analyzed the...

Seed germination is first critical and the most sensitive stage in the life cycle of plants compromise the seedlings establishment. Salt and drought tolerance testing in initial stages of plant development is of vital importance, because the seed with more rapid germination under salt or water deficit conditions may be expected to achieve a rapid s...

The objective of this work was to investigate the genetic variation of protease inhibitor in varieties of soybeans. Genetic variation of the Kunitz trypsin inhibitor represented by a 21-kD protein (KTI) and the Bowman-Birk trypsin–chymotrypsin inhibitor (BBI) in cultivated and wild soybean varieties were evaluated. We also performed endonuclease he...

2014): Morpho-chemical characterization of dry and snap bean (Phaseolus vulgaris L.) landraces collected on Fruška Gora MT..-Genetika, Vol 46, No. 1, 301-313. Disappearance of old cultivars, including dry and snap bean (Phaseolus vulgaris L.) has been accelerated in last five to six decades, which mainly led to great genetic impoverishment. For all...

The introduction of genetically modified herbicide tolerant rapeseed has raised questions concerning the possible transfer of transgenes into wild relatives or neighbouring fields with similar crops. Pollen of rapeseed can be spread in the area and if a non-GM crop is fertilised by GM pollen, some percentage of the collected seed product will conta...

SUMMARy Tomatoes are parasitized by a number of pathogens, including Fusarium oxysporum f. sp. lycopersici, causal agent of fusarium wilt. Fresh vegetable fruits can be contaminated with vari-ous fungi that produce mycotoxins, which is an important issue for human health. The objec-tive of this paper was to isolate, determine, and identify causal o...
