Abstract Obtaining red quality wines depends on the raw matter composition and also on the extraction technology, used in the processing of grape and must. Thus, two methods of maceration-fermentation on lees (classical and in rotating tanks), two thermal methods (thermomaceration and microwave maceration) and two methods rarely used industrially in wine-making (cryomaceration and ultrasound maceration) were experimented. Even in the years with less than favorable climatic conditions, from Merlot grape variety one obtained for the most part, legally speaking, quality wines (with the exception of microwave macerated and cryomacerated wines, which had only 21-22 g/L non-reducing extract. In regard to alcohol content, all obtained samples had more than 11% vol. The obtained Merlot wines were rich in glycerol (8-9 g/L), fact that favorably influenced their organoleptic traits. Total phenolic content had values between 1,97 and 2,86 g/L for the Merlot wines obtained through macerationfermentation and thermomaceration. Ultrasound maceration did not favor phenolic extraction from grape skins and the obtained wines were poor in anthocyans and tannins (0,94-1,1 g/L). In regard to the maceration technology used, free anthocyans were found in variable proportions in wines, between 77 and 91%. The sum of acylated anthocyans participation percentages was between 8,8 and 22,7%, and the ratio between the acetylated and cumarilated participation percentages registered small values, varietyspecific, between 1,1 and 2,8.

In the present work, we compared the phenol content and composition of fruit from the ‘Arbequina’ cultivar in four Mediterranean (in Andalucía, Southern Iberian Peninsula) and two Sub-Tropical (Canary Islands) locations throughout the harvest period. Two Mediterranean and two Sub-Tropical locations were maintained with drip irrigation, while the remaining two Mediterranean locations were in dry farming. Water availability and harvest date seemed to play more important roles than air temperature on the phenolic content and most of the studied components. The variability associated with location was a result of the high values observed in the two Mediterranean locations in dry farming, with respect to the other four maintained with drip irrigation. Few differences were found among the four drip-irrigated locations, despite the fact that two were Mediterranean and the other two Sub-Tropical. In addition, a sharp decrease was observed during the harvest period for phenolic content and most of the phenolic compounds.

Lotus corniculatus is a highly diverse legume with good adaptability to different soil and climatic conditions. The objective of this research was to estimate the phenotypic diversity of individual L. corniculatus plants growing under two different habitat types with different grazing management. The collection of plant material was conducted in four forested and four open grassland sites in northern Greece. Plants from open grassland had significantly lower leaf area, leaf perimeter, leaf length, leaf width and internode length compared to those from the forest. This morphological differentiation could be contributed to by differences in grazing intensity. Plants from open grasslands had significantly higher total phenols and condensed tannins, but lower crude protein content compared to those from the forest. Environmental factors in association with grazing management are the main contributors to the highly divergent concentrations of phenols, tannins and condensed tannins.

Semi-natural grasslands are particularly important in mountainous areas of Romania, being the only source of forage for many farmers. The aim of this study was to investigate the changes in forage quantity and quality as a result of Urea Ammonium nitrate (UAN) liquid fertilization. The experiment was carried out in the eastern part of Apuseni Mountains, Romania on a Festuca rubra L.-Agrostis capillaris L. grassland located at 1240 m altitude. Studies were made over three years of experimental trial (2014–2016) and covered four experimental plots in three replicates, as follows: V1–control plot, unfertilized; V2–plot fertilized with 50 kg UAN ha−1 year−1; V3–plot fertilized with 75 kg UAN ha−1 year−1, and V4–plot fertilized with 100 kg UAN ha−1 year−1. The experimental plots were harvested once per year and the botanical composition, dry matter yield and forage quality were assessed. Our results showed important changes in forage quantity, quality and diversity as a result of UAN fertilization. Starting from the second experimental year the dominance/co-dominance ratio changed favoring the species from Poaceae family. Dry matter increased as a result of UAN fertilization but forage quality was negatively affected by the higher percentage of participation of species from other botanical families which have higher crude fiber content and lower crude protein. Based on our results we recommend moderate fertilization with UAN up to 50 kg UAN ha−1 year−1 for semi-natural grasslands located in soil-climatic conditions similar to those in our experiment.

Currently, one of the least expensive options for renewing eroded soils is the sowing of grasses for the production of cheap quality fodder adapted with updated soil and climatic conditions. Analysis presented in the paper shows that one of the main conditions for balanced feeding of cows is to provide sufficient level of mineral elements with feeds. This guarantees not only high productivity and quality, but also effective use of meadow grass stands. On the basis of the studies carried out, it is determined that a sufficient number of mineral elements are present in the feed on the variants of the experiment, where a mixture of  Medicago sativa alfalfa crop, Lotus corniculatus lyadvenets Horned was sown. It has been established that leguminous grasses with phosphorus-potassium fertilizer positively influence some indicators of the composition of mineral elements in the forage of one-species perennial crops and their mixtures. The grass-legume mixture contained the following herbs: Medicago sativa alfalfa crop, Lotus corniculatus lyadvenets Horned, Bromus rump beardless inermis, and Lolium multiflorum with the fertilizer  N60P60K90.  The mineral content of the fertilizer provides the grass-legume mixture  with enough phosphorus (0.43%), potassium (2.70%), calcium (0.39%), magnesium (0.20%) and sodium (0.13%)

(1) Understanding tree seedling responses to water, nutrient, and light availability is crucial to precisely predict potential shifts in composition and structure of forest communities under future climatic conditions. (2) We exposed seedlings of widespread Central European tree species with contrasting leaf habit, deciduous broadleaves (DB) and evergreen conifers (EC), to factorial combinations of manipulated precipitation (100% and 50% of ambient), shade (40% and 60% of full sunlight), and nutrient availability (low and high NPK), and measured specific leaf area, C/N ratio, soluble sugars, starch and non-structural carbohydrate concentration, and δ13C of the leaves. (3) We found contrasting effects of water and nutrient availability on foliar traits of the two species groups: EC exhibited higher tolerance to low resource availability but also less plasticity in foliar traits, which is congruent with a “slow” resource strategy. In contrast, foliage of DB reacted particularly to altered nutrient availability, corresponding to a “fast” resource strategy with high foliar plasticity and rapid adjustments to resource fluctuations, commonly adopted by species with high growth rates. (4) We conclude that DB will respond to environmental change with foliar acclimation, while EC will either tolerate, to some extent, or shift their distribution range in response to environmental change.
