L’impiego alimentare di orzo germinato nella produzione di latte ovino biologico

2011

Food use of barley sprouts in organic sheep milk production. Hydroponic forage, used when fresh forage is scarce, represents a good alternative feed for milking ruminants, also in organic farming systems, where it can reduce the forage/concentrate ratio. This study evaluated the effect of barley sprouts (BS) in the diet on nutrients utilization and milk production from organic ewes. Eighteen ewes were divided into 3 groups and fed with 3 diets. Animals was fed with hay ad libitum and supplemented by: 0.6 kg/d of concentrate and 4 kg/d of BS (B100); 0.9 kg/d of concentrate and 2 kg/d of BS (B50); 1.2 kg/d of concentrate (C). Supplied and residual feeds and milk yield were recorded and sample…

Simulation of the effects of climate change on barley yields in rural Italy

2009

The Greenhouse effect is considered to be one of the most influential factors on climate change today, especially where temperature and rainfall levels/distribution are concerned, making it of considerable importance in the field of Agronomy. Crop growth and development simulation models are a valuable cognitive tool in understanding water and nutrient dynamics in soil/plant systems. This paper looks at the direct and indirect effects of climatic changes on average barley yields. The complex nature of the study rendered the use of mathematical simulation models essential, both for predicting future climate conditions and for the simulation of crop growth and development. Of the different si…

Soil quality indicators as affected by a long term barley-maize and maize cropping systems

2011

Most soil studies aim a better characterization of the system through indicators. In the present study nematofauna and soil structure were chosen as indicators to be assess soil health as related to agricultural practices. The field research was carried out on the two fodder cropping systems continuous maize (CM, Zea mays L.) and a 3-year rotation of silage-maize – silage-barley (Hordeum vulgare L.) with Italian ryegrass (R3) and grain-maize maintained in these conditions for 18 years. Each crop system was submitted to two management options: 1) the high input level (H), done as a conventional tillage, 2) the low input level (L), where the tillage was replaced by harrowing and the…

Annata straordinaria per l’orzo al Nord Italia

2016

La Rete delle prove nazionali di orzo da zootecnia per l’annata 2015-2016 evidenzia ottimi risultati produttivi soprattutto al Nord Italia. In questo articolo riportiamo la valutazione di 39 varietà ripartite in tre diversi gruppi varietali a seconda dell’areale interessato dalla sperimentazione (Nord, Centro, Sud e Isole)

Research Regarding the Use of Wheat Biodiversity for Obtaining some Cereal-Based Fermented Mashes

2012

International audience; Cereal-based fermented beverages are an opportunity to include probiotics and fiber in human nutrition. Nowadays, increasing the interest for rediscovering the benefits, on scientific basis, of traditional fermented beverages based on cereals. Fermented mashes based on different cereal grist, namely Braga in Romanian, is a healthy and nutritious beverage, a source for new functional products with beneficial effects on human health. Physical-chemical and sensorial characteristics of these beverages depend on the ingredients and method of preparation. In this article was analyzed the influence of the five varieties of wheat on the main physical-chemical and sensorial c…

Efficiency of acetic acid and formic acid as a catalyst in catalytical and mechanocatalytical pretreatment of barley straw

2016

Abstract In this study, the potential of organic acids (formic acid, acetic acid) in a catalytical and mechanocatalytic conversion of lignocellulosic barley straw to valuable sugars is explored using sulfuric acid as a reference. Acid-catalyzed hydrolysis has been carried out with acid-impregnated samples as well as unmodified barley straw. In the mechanocatalytical approach, pretreatment consists of impregnation with the acid catalyst and mechanical treatment by ball milling following chemical hydrolysis. Straw samples and residues were analyzed by Fourier transform infrared spectrometry (FT-IR) whereas hydrolysate analysis was based on total reducing sugar (TRS) determination following th…

Production of Functional Crackers Enriched with Olive (Olea europaea L.) Leaf Extract

2016

In recent years, considerable interest has been shown in the functional properties of foods, and a relevant role has been played by phenolic compounds, able to scavenge free radicals. A more sustainable agriculture has to emerge to guarantee food supply over the next years. Wheat, corn, and rice are the most common cereals cultivated, but also other cereal species, such as barley can be appreciated for their peculiarities. Barley (Hordeum vulgare L.) is a C3 winter cereal that shows high resistance at drought and salt stresses. There are growing interests in barley as ingredient for the production of functional foods due to its high content of phenolic compounds and Beta-glucans. In this re…

The influence of α-aminophosphonic acids on the activity of aminopeptidase from barley seeds—an approach to determine the enzyme specificity

2015

Inhibitory potencies of 24 α-aminophosphonic acids against barley seeds (Hordeum vulgare L.) metallo-aminopeptidase have been determined to evaluate structural requirements of this enzyme. The enzyme was sensitive mostly to the influence of phosphonic acid analogues of phenylalanine and its homologues, thus showing narrow specificity if compared with porcine aminopeptidases M1 and M17 and with Plasmodium aminopeptidase M17.

Anther Culture Effectiveness in Producing Doubled Haploids of Cereals/ Putekðòu Kultûras Efektivitâte Graudaugu Dubultoto Haploîdu Izveidoðanâ

2014

Abstract Our goal was to improve the method of obtaining double haploids (DH) by anther culture from Latvian breeding material for several agriculturally important cereals in Latvia: barley, spring and winter wheat. Hybrids from Latvian breeders were initial material. It was found that copper (2.5 mg/l) added to barley anther pre-treatment media and to both barley (C3) and wheat (liquid AMC) induction media, resulted in a higher percentage of green plants-regenerants. In general, the winter wheat hybrids exhibited lower embryogenesis than spring wheat hybrids. Obtaining a large number of DH lines from barley and wheat hybrids with unknown androgenesis response can be organized in two stages…
