The aim of this work was to investigate the effect of meteorological conditions on resveratrol concentration of red wines produced in Piacenza viticultural region (Italy). In this regard, six representative estates producing Colli Piacentini Gutturnio DOC (a blend of V. vinifera L. cvs. Barbera and Croatina) vintage wines were analysed for trans- and cis-resveratrol over an 8-year period (1998–2005). Grapes were taken from the same vineyard in each estate by using the same enological practices over the entire investigated period. The meteorological conditions corresponding to the production areas were recorded, and bioclimatic indices were calculated as well. Overall, cis-resveratrol concentration was negatively correlated to Huglin index and August mean temperature, whilst positive correlation coefficients were found when considering the Selianinov index and the rainfall of September.

Today, there are about 12,000 plants in the world that have healing properties and are used in both traditional and folk medicine. One of these plants is Ginkgo biloba L. In recent years, interest in its cultivation has increased in Ukraine, and improving the technology of growing this plant in the Ukrainian North-East is a relevant problem. Studies of G. biloba plants growing in the experimental area of Sumy NAU were conducted. On the basis of morphometric analysis, a number of morphoparameters were measured (plant height, annual growth of shoots, number of leaves, leaf size and leaf area, phytomass of the shoots, phytomass of leaves and phytomass of the stem, diameter of the shoots). The vital analysis, as well as the variance, correlation and regression analyses were carried out. G. biloba seedlings up to 3–4 years of life with different growing technology have a height of 25–30 cm and form 13–17 leaves per plant. The totality of morphometric characteristics in all variants of the G. biloba plant experiment corresponded to an equilibrium population of equilibrium type, in which in close proportions individuals of all three vitality types are present: a, b, and c. But at the same time a higher proportion (40 %) of individuals of class "a" was in the variant with the cultivation of G. biloba in greenhouse. The smallest part of individuals of high viability (only 20 %) was formed by cultivation of G. biloba in open soil without protection of the agro-grid. The ecological-coenotic stability of G. biloba has been noted many times, a certain limitation of G. biloba cultivation may be that this plant is light loving and thermophilic, but the climatic conditions of the Ukrainian North-East are favorable for it. Complex studies have shown the prospects and feasibility of growing G. biloba in the conditions of t the Ukrainian North-East as medicinal raw materials. Despite the stressful growing conditions for G. biloba, this species is characterized by high stability and adaptability, which is confirmed by our comparative morphometric and vital analysis of plants. Given that the age of the seedlings is negligible, further studies to determine the adaptability of G. biloba plants to growing conditions are not only desirable but also necessary.

Abstract Key message We developed a climatic response function using 20-year tree height observed from 45Ginkgo bilobaplantations in China and used it to predict the growth and habitat responses to anticipated climate change. We projected northward and upward shifts in the species habitat and productive areas, but a dramatic contraction of the species distribution is unlikely to occur at least during the present century. Context Ginkgo biloba is the only living species in the division Ginkgophyta. The species exists in small natural populations in southeastern China but is cultivated across China and the world. The species’ future under climate change is of concern. Aims This study was initiated to model the species’ growth response to climate change and to predict its range of suitable habitat under future climates. Methods Using height data from 45 20 years old plantations growing under a wide range of climatic conditions across China, we developed univariate and bivariate climatic response functions to identify the climate requirements of the species. Results According to the amount of variance explained (> 70%) and the high level of agreement (> 99%) with independent species occurrence coordinates, the developed climate response function was highly accurate and credible. Projections for future periods (2011–2040, 2041–2070, and 2071–2100) under the Representative Concentration Pathway 4.5 (RCP4.5) scenario indicated that the areas of potential suitable habitat would increase (25–67 million hectares). It would also be associated with northward (0.21–0.62° in latitude) and elevational (24–75 m) shifts. Conclusion Global climate change is projected to increase the area of potential suitable habitats for Ginkgo and shift its spatial distributions northward and upward.

Global Food

<p>The majority of global food production, as we know it, is based on agricultural practices developed within stable Holocene climate conditions. Climate change is altering the key conditions for human societies, such as precipitation, temperature and aridity. Their combined impact on altering the conditions in areas where people live and grow food has not yet, however, been systematically quantified on a global scale. Here, we estimate the impacts of two climate change scenarios (RCP 2.6, RCP 8.5) on major population centres and food crop production areas at 5 arc-min scale (~10 km at equator) using Holdridge Life Zones (HLZs), a concept that incorporates all the aforementioned climatic characteristics. We found that if rapid growth of GHG emissions is not halted (RCP 8.5), in year 2070, one fifth of the major food production areas and one fourth of the global population centres would experience climate conditions beyond the ones where food is currently produced, and people are living. Our results thus reinforce the importance of following the RCP 2.6 path, as then only a small fraction of food production (5%) and population centres (6%) would face such unprecedented conditions. Several areas experiencing these unprecedented conditions also have low resilience, such as those within Burkina Faso, Cambodia, Chad, and Guinea-Bissau. In these countries over 75% of food production and population would experience unprecedented climatic conditions under RCP 8.5. These and many other hotspot areas require the most urgent attention to secure sustainable development and equity.</p>

Root Lesion Nematodes

Root lesion nematodes (Pratylenchus spp.) hinder dryland wheat production worldwide. Montana, a leading U.S. wheat production region, has climatic conditions favorable for Pratylenchus spp. A 2006-2007 statewide soil survey revealed damaging populations of Pratylenchus neglectus, primarily in winter wheat production areas of Montana, whereas P. thornei was not found. Analyses of wheat yields in infested fields revealed negative correlations between yields and spring nematode populations (all P < 0.05 and all R2 > 0.2). Statewide yield losses due to root lesion nematodes were an estimated 12 and 15% for winter wheat in 2006 and 2007, respectively. A subsequent study conducted in 2008 to 2009 revealed significant differences in reproductive success of P. neglectus among seven rotation treatments (P < 0.001). Nematode populations persisted from spring to fall under fallow, barley, pea, and camelina; increased under winter wheat and canola; and decreased under lentil. Populations were sustained through winter following winter wheat and barley but declined following canola, camelina, pea, lentil, and fallow. A screening of 19 barley lines for resistance to P. neglectus revealed significant variation in resistance among entries (P < 0.001), with ‘Harrington’ barley displaying promising levels of resistance. Development of resistant wheat cultivars remains a principal goal in managing this nematode.

During the last century the medicinal and aromatic plant sector has became a successful part of the Hungarian Agriculture. Some of the national products have been accepted as a special Hungarian ones ("Hungaricum"), evaluated on the world market, respectfully. By the estimates the cultivation area of medicinal and aromatic plants increased up to 37,000-42,000 hectares and considerable amount — about 10, 000-15, 000 tonnes of dry biomass — are produced by utilisation of Hungarian indigenous flora, year by year. In the present work ecological requirements of 97 collected and 55 cultivated medicinal and aromatic plants are characterised. Based on the analysis of -Ts (temperature regime values) about 63 per cent of cultivated species came from Submediterranean and Mediterranean type of habitat, originally, while the majority of collected plants (61.8 per cent of them) prefer the deciduous forest conditions. The differences between collected and cultivated species are appreciable too, if the distributions of their characteristic water regime ('W' values) are compared. The majority of cultivated species require dry (moderate dry) and fresh (moderate fresh) habitats, while the amplitude of water requirement of collected species is much more wide-ranging. The regional specialisation of Hungary according to production of medicinal and aromatic plants is known from the beginnings of the 20th century. As a result of spontaneous process seven well-defined production areas were developed. The relationship between regions, their climatic conditions and spectrum of species produced there are analysed.

Antioxidant And Antimicrobial Activities

The composition and properties of natural honeys differ with plant species on which the bees forage and the climatic conditions of the production areas. In Ethiopia, Amhara and Tigray are neighboring regions consisting of different agricultural activities and blossoms from different types of vegetations which may influence the natural composition and hence the properties of honey. So, the aim of the current study was to assess the quality of honey from selected districts of the two regions. In the study, 18 composited honey samples were collected from six selected districts and analyzed for selected physicochemical parameters and antioxidant and antimicrobial activities. The analyses of physicochemical parameters were carried out following standard procedures of IHC and QSAE. The antioxidant activity was determined by analyzing the RSA using DPPH while the antibacterial activities were determined by the agar well diffusion method. The moisture, ash content, electrical conductivity, pH, free acidity, reducing sugar, and sucrose content of the honey samples were found to be in the range 16.34 ± 0.26 to 19.83 ± 0.43 %, 0.08 ± 0.00 to 0.45 ± 0.03 %, 0.19 ± 0.00 to 0.89 ± 0.03 mS/cm, 3.79 ± 0.04 to 4.20 ± 0.01, 19.56 ± 1.13 to 38.11 ± 1.54 meq/kg, 62.10 ± 0.48 to 66.37 ± 0.20 %, and 1.35 ± 0.08 to 5.96 ± 0.10 %, respectively. The total phenolic content ranged from 1165.60 ± 23.45 to 1854.83 ± 10.47 mg/kg with antioxidant activity of 21.64 ± 0.26 to 36.12 ± 0.52 AEAC/100 g. The total phenolic contents showed strong correlation with RSA. Furthermore, all honey samples showed an antibacterial activity varying from 23.23 ± 0.12 to 28.84 ± 0.24 mm.

Critical Overview

Ponds in agricultural areas are ubiquitous water retention systems acting as reactive biogeochemical hotspots controlling pesticide dissipation and transfer at the catchment scale. Several issues need to be addressed in order to understand, follow-up and predict the role of ponds in limiting pesticide transfer at the catchment scale. In this review, we present a critical overview of functional processes underpinning pesticide dissipation in ponds. We highlight the need to distinguish degradative and non-degradative processes and to understand the role of the sediment-water interface in pesticide dissipation. Yet it is not well-established how pesticide dissipation in ponds governs the pesticide transfer at the catchment scale under varying hydro-climatic conditions and agricultural operation practices. To illustrate the multi-scale and dynamic aspects of this issue, we sketch a modelling framework integrating the role of ponds at the catchment scale. Such an integrated framework can improve the spatial prediction of pesticide transfer and risk assessment across the catchment-ponds-river continuum to facilitate management rules and operations.

In recent years, interest in cultivating Ginkgo biloba L. as a medicinal plant has grown in Ukraine, and improvement of the technology of growing this plant in the conditions of the North-East of Ukraine is a relevant problem. The purpose of this article to present research on the morphological structure, growth and viability of young G. biloba plants in grown from seeds by different technologies and comparative analysis of growth and development of G. biloba plants under greenhouse conditions and on open soil. The experiment on G. biloba cultivation was initiated in 2014 in three variants (the plants were grown from the seeds). Variant No 1: G. biloba growing in a greenhouse at 60–80% humidity and temperatures not below +27 ºС; shading (shading level 60%) by green agronetting. Variant No 2: growing in open soil; shading (shading level 60%) by green agronetting; the climatic conditions were typical for Sumy region. Variant No 3: growing in open soil; there was no shading; climatic conditions were typical for the Sumy region. Plant analysis was conducted in June 2018. The following morphometric parameters of G. biloba plants were measured: plant height, annual growth of shoots, number of leaves, leaf size and leaf area, phytomass of the shoots, phytomass of leaves and phytomass of the stem, diameter of the shoots. The sampling used 60 samples. The leaf area was determined by the method of drawing contours on millimeter paper. Statistical processing of research results was carried out by generally accepted modern methods of mathematical statistics using dispersion, correlation, regression and vital analysis. In the conditions of the Ukrainian North East, G. biloba seedlings can be grown successfully in greenhouses and open soil, both with 60% shade by agronetting and without it. Differences between the plants grown in such conditions are insignificant and statistically unreliable. The obtained three to four year old G. biloba seedlings grown using different technologies were 25–30 cm in height and formed 13–17 leaves per plant. The seedlings were of quite high viability (Q is 0.22–0.30) and morphostructural integrity (67.8%). The output of viable seedlings (vital classes “a” and “b”) in variant 1 was 60%, variant 2 45% and variant 3 60%. Ecological-cenotic stability of G. biloba was observed repeatedly, though certain limitations on G. biloba cultivation may be that the plant is photophilic and thermophilic. But the conducted experiments show that the climatic conditions of the Ukrainian North-East are quite favourable for this species. Based on the data obtained for the Ukrainian North-East, it is possible to recommend the technology of growing G. biloba seedlings in open soil without agronetting as quite effective and low-cost.
