<abstract xmlns="http://www.w3.org/1999/xhtml">Wheat (genus <italic>Triticum</italic>) is considered to be an important source of polyphenols, plant secondary metabolites with numerous health-promoting effects. Many phytochemicals are responsible for the high antioxidant activity of whole grain products. However, there is a lack of information about composition of phenolic acids and their concentrations in different <italic>Triticum</italic> species. Despite the fact that the increased consumption of whole grain cereals and whole grain-based products has been closely related to reduced risk of chronic diseases, bioactive compounds found in whole grain cereals have not achieved as much attention as the bioactive compounds in vegetables and fruits. Recent studies have revealed that the content of bioactive compounds and antioxidant capacity of whole grain cereals have been regularly undervalued in the literature, because they contain more polyphenols and other phytochemicals than was reported in the past. Phenolic acids represent a large group of bioactive compounds in cereals. These compounds play a significant role in the possible positive effects of the human diet rich in whole grain cereals, especially in wheat and provide health benefits associated with demonstrably diminished risk of chronic disease development. Ferulic acid, the primary and the most abundant phenolic acid contained in wheat grain, is mainly responsible for the antioxidant activity of wheat, particularly bran fraction. In this paper, selected phenolic compounds in wheat, their antioxidant activity and health benefits related to consumption of whole grain cereals are reviewed.</abstract>

Phenolic acids and antioxidant activity of wheat species: a review

<abstract xmlns="http://www.w3.org/1999/xhtml">The aim of research was to analyse winter wheat of different grain colour and to compare newly bred coloured genotypes from our breeding in grain yield and technological and nutritional quality. The set of seven purple, five blue and four yellow wheats of different origin, including seven newly bred genotypes from Vígľaš-Pstruša, was evaluated in the field experiments established by randomised complete block design in two replications in Piešťany, in the vegetations 2012/13 and 2013/14. In seven wheat varieties differing in grain colours (selected after two of each colour plus control red variety Ilona) anthocyanin composition was evaluated by HPLC analysis. Significant differences were between growing years and among colour groups in most analysed traits. Blue grain newly bred K 3575 699/3 showed the highest anthocyanin content (by 33.5% higher compared to blue grain registered variety Scorpion). However, blue grain genotypes showed negative agronomic traits combined with low number and grain weight per spike and high plant height. In new purple variety PS Karkulka, declared grain yield and its quality were confirmed and the highest mineral content (Fe, Zn, Cu, Mn) was found in selected set. Purple grain newly bred PS 5711 had lower anthocyanin content (by 17.7%), but in quality it was comparable to PS Karkulka. Varieties with yellow endosperm showed the highest number and weight of grains per spike, however it was significantly lower to Ilona. The breeding goal of coloured winter wheat is still to improve the grain yield as well as additional agronomics traits.</abstract>

Variability of quantitative and qualitative traits of coloured winter wheat

<abstract xmlns="http://www.w3.org/1999/xhtml">The association of phytoplasma was investigated in symptomatic tomato (<italic>Solanum lycopersicum</italic> L.), eggplant (<italic>Solanum melongen</italic> L.), mallow (<italic>Malva</italic> spp.) and Bermuda grass (<italic>Cynodon dactylon</italic> L.) plants exhibiting witches’ broom and white leaf diseases, respectively. Total DNA was extracted from tomato (n=3), eggplant (n=2), mallow (n=2) and Bermuda grass (n=8) samples. Direct polymerase chain reaction (PCR) was performed using P1/P7 primer set, then PCR products were sequenced. Sequences obtained from tomato, eggplant and mallow shared 99% maximum nucleotide identity with phytoplasma belonging to subgroup 16SrII-D, and resulted therefore ‘<italic>Candidatus</italic> Phytoplasma australasia’-related. Sequences obtained from Bermuda grass showed 100% maximum nucleotide identity to 16SrXIV-A subgroup and were ‘<italic>Ca</italic>. P. cynodontis’-related. The study presents the first molecular confirmation and sequence data of presence of ‘<italic>Ca.</italic> P. australasia’ and ‘<italic>Ca</italic>. P. cynodontis’ in Iraq.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The aim of this study is to investigate the effects of gas transit pipeline temperature on soil moisture, soil temperature and yield of harvest crops. The study area was located in the village Ivanka pri Nitre (Nitra District, Southwestern Slovakia). Soil type in the site is Orthic Brown Chernozem. Temperature of the transported gas increased the soil temperature in the range of 2.07°C to 3.4°C measured in a depth ranging from 250 mm to 350 mm above the gas lines. The temperature also reduced soil moisture by 1.27‒3.18 percentiles of weight. Yield of the winter wheat grown above the gas lines was higher by 9.40% in 2004 and by 13.06% in 2006. Yield of the sunflower grown above the gas lines was higher by 8.05% in 2005. In treatment 1, organic fertilisation in a dose of 50 t/ha affected the yield of the winter wheat above the gas pipeline and the yield increased by 13.95% in 2004.</abstract>
