The extension and renewal of cultivar assortment is one of the key elements in the improvement of apricot production. Competitiveness can only be achieved by planting cultivars which meet all market requirements and yield reliably under the environmental conditions of the given production site. Beside breeding programmes, the range of cultivars can also be extended by the domestication of foreign cultivars. Most apricot cultivars have low ecological tolerance, therefore, cultivars improved or developed in other countries should only be involved in production after due consideration. The suitability of such cultivars has to be examined for several years. Foreign apricot cultivars have been tested in our cultivar collection for over 10 years. Hereby, the most important aspects of market value and the adaptability to the environmental conditions of the production site are demonstrated. According to the results of our examinations the production of early ripening 'Orange Red' and `Goldrich' can be promising in Hungary. From cultivars ripening in the peak season only those are expected to be widely produced which differ from Hungarian cultivars or surplus them in some respects. From the cultivars examined 'Harogem' which ripens at the same time as `Gönci magyar kajszi' has remarkably aesthetic fruits with glossy surface, while the large fruits of `Hargrand' has firm pulp. Late ripening cultivars have significant importance in the northern border of production. According to our examinations the cultivars 'Callatis', `Comandor and `Sirena' are applicable in Hungary to extend the harvesting season.

Speleothem formations are one of the most important and informative objects in paleoclimatological research. However, in order to interpret the data that reflect environmental conditions, we have to know the operation of the given cave, and it should be determined how the composition of the carbonate formed at the given site is related to the changes in the environmental parameters. The study presents the results of stable isotope geochemical analysis of speleothem formations and carbonate precipitated on glass plates collected in the Vacska Cave (Pilis Hills). The youngest layer of carbonate formations, formed in the last 1-2 decades, shows an isotope fractionation sign indicating strong ventilation, with the exception of a single site farthest from the entrance to the cave. The isotope shift was also accompanied by a change in carbonate fabric. Preceding the fabric change, the carbonate of the speleothem formations did not show ventilation-related shifts in the isotope compositions, suggesting that the exploration and opening of the cave areas may have caused the change. Based on this, we recommend the installation of local closures in the Vacska Cave and in the entire Ariadne cave system. The study provides a good example of how the results of basic research can be utilized in practical environmental protection, in the preservation of a strictly protected cave environment.

Stilbenoids such as t-piceid, t-resveratrol, ε-viniferins, and t-pterostilbene can differ significantly among grape cultivars and years due to variation in environmental conditions and subsequent stressors encountered during a year. This study evaluated diverse muscadine grape cultivars for their ability to consistently produce four major stilbenoids such as t-piceid, t-resveratrol, ε-viniferins, and t-pterostilbene irrespective of environmental changes that can impact their production. Berries from forty-two muscadine grape cultivars were collected for three years (2013, 2014, and 2015) to measure stilbenoids. Results showed significant differences in the composition of four stilbenoids among the muscadine cultivars. The highest level of stilbenoids was observed in ‘Fry Seedless’ (270.20 µg/g fresh weight) in each of the three consecutive years tested followed by ‘Pride’ (46.18 µg/g fresh weight) while ‘Doreen’ produced the lowest level of stilbenoids (1.73 µg/g fresh weight). Results demonstrated that certain muscadine grape cultivars consistently produced varied levels of the four major stilbenoids year after year. Based on the total content of stilbenoids, the 42 muscadine cultivars studied were grouped into three categories such as High, Medium and Low stilbenoid-containing cultivars. This information will help establish new vineyards with cultivars that are less prone to variations in environmental conditions and can consistently produce stilbenoid-rich muscadine grape berries with enhanced market value to promote consumer health.

ABSTRACT Oil spill dispersants are not the only answer in responding to oil spills, nor will they be effective in every case. However, as recent incidents such as the Sea Empress have demonstrated, when they are used immediately on a dispersible oil they can provide a very significant net environmental or economic benefit. Dispersant pre-approvals are required if dispersants are to be used effectively. However, the danger associated with pre-approvals is that dispersant could be used in every response operation without due consideration to whether the oil is likely to be dispersible under the given environmental conditions and whether dispersing some of the oil will result in a net environmental or economic benefit.

Дан обзор результатов ампелографической оценки перспективных розовоягодных сортов винограда Анюта, Аркадия розовая, Виктор, Памяти хирурга в условиях Анапо-Таманской зоны Краснодарского края. Агротехника соответствовала общепринятой для данной культуры и зоны. Схема посадки - 3,0 х 2,5 м. Кусты формировались по типу высокоштамбового двуплечего горизонтального кордона. Все агробиологические учеты проводились по общепринятым методикам. На кустах формировалась одинаковая нагрузка побегами и гроздями. Анализ метеорологических условий периода вегетации, агробиологических и хозяйственно-технологических показателей изучаемых сортов свидетельствует о том, что почвенно-климатические условия Анапо-Таманской зоны Краснодарского края являются благоприятными для их возделывания в неукрывной культуре. Сорта Виктор и Аркадия розовая были отнесены к группе сортов очень раннего срока созревания, сорт Памяти хирурга - раннего, а сорт Анюта - к группе сортов среднепозднего срока созревания. Суммирование рангов сортов по признакам позволяет классифицировать их по комплексной ценности (в убывающем порядке ряда): Виктор, Анюта, Аркадия розовая и Памяти хирурга. В конце ряда - контрольный сорт Кишмиш лучистый. То есть все сорта народной селекции по комплексу биолого-хозяйственных признаков превосходят контрольный сорт и потому их следует рассмотреть как перспективные для районирования в Южно-Предгорной зоне Краснодарского края. Анализ результатов исследований показал, что для производства свежего столового винограда в условиях Анапо-Таманской зоны Краснодарского края в неукрывной культуре рекомендуется выращивание выделившихся по комплексу биолого-хозяйственных признаков сортов Виктор, Памяти хирурга, Аркадия розовая и Анюта. The article provides the summary of results on ampelographic assessment of promising rose-berry grape varieties ‘Anyuta’, Arcadia Rose’, ‘Victor’, ‘Pamyati Khirurga’ in the Anapo-Taman zone of the Krasnodar Territory. Agricultural techniques corresponded to those generally accepted for the given culture and zone. The planting pattern was 3.0 x 2.5 m. The bushes were trained as high-head two-armed horizontal cordons. All agrobiological surveys were carried out according to generally accepted methods. Identical loading with shoots and bunches was trained on the bushes. The analysis of meteorological conditions of the growing season, agrobiological and economic-technological parameters of the studied varieties indicates that the soil and climatic conditions of the Anapo-Taman zone of the Krasnodar Territory are favorable for their cultivation in open-earth culture. The varieties ‘Victor’ and ‘Arcadia Rose’ were attributed to the group of very early ripening varieties, the variety ‘Pamyati Khirurga’ - early, and ‘Anyuta’ - mid-late ripening varieties. Summing-up of varietal ranges according to the characteristics allows classify them according to their complex value (in range in descending order): ‘Victor’, ‘Anyuta’, ‘Arcadia Rose’ and ‘Pamyati Khirurga’. The control variety ‘Kishmish Luchistyi’ is at the end of this range. It means that all varieties selected by local inhabitants are superior to the control variety in terms of the complex of biological and economic characteristics, and therefore they should be considered as promising for zoning in the South Piedmont zone of the Krasnodar Territory. The analysis of the research results showed that in order to produce fresh table grapes in the Anapo-Taman zone of the Krasnodar Territory in open-earth culture, it is recommended to cultivate the varieties ‘Victor’, ‘Pamyati Khirurga’, ‘Arcadia Rose’ and ‘Anyuta’, distinguished by a complex of biological and economic characteristics.

Grain protein content and grain yield data were collected from 11 Interstate Wheat Variety Trials (IWVT) and other sources. The level of variation in grain protein content beyond that attributable to covariation in environment and yield was estimated using a generalized linear model. A range of almost 4% in corrected protein content was found among 204 lines tested in IWVT. The Western Australian cv. Tincurrin was approx1% lower in grain protein content than any other line, while Shortim, Sun 43A, QT2200-20, QT2612-1 and Sun 92A were all 1.4-1.7% higher than the pooled mean of 4 control cultivars (Cook, Eagle, Halberd and Oxley). Accessions did not vary significantly in protein content with change in yield. Results from a range of other independent trials confirmed those from IWVT. Wheats genetically capable of producing a higher concentration of protein in their grain at a given yield level came principally from the Sydney University and Queensland breeding programmes, and those producing a lower concentration principally from Victoria and Western Australia. Grain hardness was independent of grain protein content and many low protein hard wheats entering the IWVT fell well outside current international market requirements.

Effects of the cut flower preservative Flower Care varied significantly during the different simulated stages of the production–marketing–consumer cycle. The vase-life of the cut rose Rosa hybrida L. cv. Forever Yours was extended the longest when the preservative was used during the consumer period. When used during the simulated wholesale and retail marketing periods this extension in vase-life was less. The effects of the preservative were least when it was used during the immediate postharvest period. The final size of the flower increased significantly when the preservative was used during the simulated wholesale and consumer periods. The experimental data were used in a regression equation for calculation of vaselife at any concentration of preservative used under the given environmental conditions.

The objective is to analyze the trajectory of knowledge-intensive SMEs in Ciudad Juarez, with the determination to understand how the concept I4.0 has been defined. The methodology applied in- depth interviews with managers and visits to companies. The results show that the particular trajectory of the maquiladora industry in this city, as well as the experience in automation of local SMEs facilitate the appropriation of the new industrial model. The originality of the study relies on the fact that it is one of the few qualitative studies that explore the incursion of SMEs to I4.0 on the northern border of Mexico. The conclusions show that the adverse environmental conditions have meant that some SMEs fail in their evolution towards I4.0, while others have opted for hybrid models, and the most successful have managed to scale towards the new industrial model thanks to their relation with other institutions of the innovation ecosystem. The main limitation of the study is that sample is composed of 4 SMEs and the results cannot be generalized.
