Grape Cultivars

Turkey is one of main gene centers in the world for grapes. It is believed that cultivated grapes have their origins in Turkey and the surrounding countries. Vitis vinifera ssp sylvestris is the only wild grape species in this region. That is why Turkey has a very large amount of wild grapevine populations and grape cultivars which offer to grapevine breeders a valuable gene pool. Wild grapevines have significant characters for inducing the resistence to biotic and abiotic stress factors, such as resistance to lime, drought, pests and diseases. Turkey has over 1.600 local grape cultivars, among which the majority of them are conserved at the national grape collection vineyard in Tekirda?. They are mostly used as table grapes, dried grapes or for local consumptions. Wild grapes are distributed all over the country territory, mainly in the river basins and forests. Wild grape collection vineyards were established at some universities in Turkey. These grapevines will be screened for the resistance to biotic and abiotic stress factors.

Селекционерами Института Магарач в результате целенаправленной селекции создан новый бессемянный сорт винограда столового направления использования, отличающийся от сорта-эталона Кишмиш лучистый очень ранним сроком созревания, высокой продуктивностью, относительно высокой устойчивостью к биотическим и абиотическим стресс-факторам биосферы, нарядной гроздью и ягодой, и высоким качеством столового винограда. Элитная форма, оформленная как новый сорт винограда, выделена из популяции сеянцев комбинации скрещивания Подарок Запорожью (колх.) х Русбол улучшенный (колх.) 2009 г. при комплексном изучении популяций столовых форм винограда очень раннего срока созревания. В статье представлены основные ампелографические и биолого-хозяйственные параметры, которыми характеризуется новый перспективный сорт: очень ранний срок созревания (5 августа), продукционный период 110 дней. В результате экспериментальных лабораторных исследований по определению морозоустойчивости сортов и элитных форм винограда установлена средняя морозоустойчивость сорта Крымский бисер (до минус 21 С). Рекомендуемая форма куста кордон на среднем штамбе. Нагрузка 6 глазков на рожке (4 рожка). Схема посадки 3 х 1,5 м. Профилактические обработки против грибных болезней 34 раза в сезон. Возделывание сорта Крымский бисер в производственных насаждениях Южного берега Крыма позволит получать чистую прибыль с 1 га насаждений 1896.0 тыс. руб. ежегодно.As a result of targeted selection, plant selection breeders of the Institute Magarach created a new seedless cultivar of table grapes distinguished from the standard cultivar Kishmish luchistyi by a very early ripening date, high productivity, relatively high resistance to biotic and abiotic stress-factors of the biosphere, elegant bunch and berry, and high quality of table grapes. The elite form formally established as a new grape cultivar has been singled out from the seedlings population Podarok Zhaporozhyu (colchicine treated) x Rusbol ulutshennyi (colchicine treated) as a result of a cross performed in 2009 under a complex study of a population of table grape forms of a very early ripening date. The article summarizes the main ampelographic, biological and commercial parameters characteristic of the new promising cultivar: very early ripening date (5th of August), production period 110 days. Laboratory research on frost-resistance of cultivars and elite grapevine forms established average frost resistance of Krymski biser cultivar (up to -21 degrees Celsius). The recommended bush training technique is a medium trunk cordon. The load of 6 eyes on cane (4 canes on bush). The planting scheme is 3x1.5 m. Prophylactic treatment against fungal diseases 34 times per year. Cultivation of Krymski biser cultivar in commercial vineyards of the southern coast of Crimea will allow obtaining a yearly net profit of 1896.0 thousand roubles from 1 ha of plantations.

European Ash

Fraxinus excelsior L. is threatened by a variety of environmental factors causing a decline of the species. The most important biotic factors negatively affecting the condition of the F. excelsior population are fungi such as the pathogen Hymenoscyphus fraxineus. Abiotic factors with potentially harmful effect to the F. excelsior population are the accumulation of heavy metals and salinity in soils. Thus, the aim of this study was to investigate the impact of selected biotic and abiotic stress factors to determine which of them pose a threat to European ash. The study was conducted using in vitro techniques based on callus and seedlings regenerated via indirect organogenesis. Tissue cultures exclude the influence of other factors, including the environmental impact on ash extinction. The results confirmed very strong pathogenic potential of H. fraxineus in which after 14 days the callus tissue cells died as the tissue failed to activate its defense mechanisms. Experiments showed the high toxicity of cadmium in concentration of 0.027 mmol/L. Salinity caused the activity of oxidation enzymes to vary among seedlings and calluses in the control suggesting the enzymes play a role in controlling the morphogenetic development of tissue cultures.

Combined Stresses

Plants encounter several biotic and abiotic stresses, usually in combination. This results in major economic losses in agriculture and forestry every year. Climate change aggravates the adverse effects of combined stresses and increases such losses. Trees suffer even more from the recurrence of biotic and abiotic stress combinations owing to their long lifecycle. Despite the effort to study the damage from individual stress factors, less attention has been given to the effect of the complex interactions between multiple biotic and abiotic stresses. In this review, we assess the importance, impact, and mitigation strategies of climate change driven interactions between biotic and abiotic stresses in forestry. The ecological and economic importance of biotic and abiotic stresses under different combinations is highlighted by their contribution to the decline of the global forest area through their direct and indirect roles in forest loss and to the decline of biodiversity resulting from local extinction of endangered species of trees, emission of biogenic volatile organic compounds, and reduction in the productivity and quality of forest products and services. The abiotic stress factors such as high temperature and drought increase forest disease and insect pest outbreaks, decrease the growth of trees, and cause tree mortality. Reports of massive tree mortality events caused by “hotter droughts” are increasing all over the world, affecting several genera of trees including some of the most important genera in plantation forests, such as Pine, Poplar, and Eucalyptus. While the biotic stress factors such as insect pests, pathogens, and parasitic plants have been reported to be associated with many of these mortality events, a considerable number of the reports have not taken into account the contribution of such biotic factors. The available mitigation strategies also tend to undermine the interactive effect under combined stresses. Thus, this discussion centers on mitigation strategies based on research and innovation, which build on models previously used to curb individual stresses.
