Pesticides are chemicals that are used to control and avoid fruit losses from pests and diseases in fruit production. Various kinds of pesticides have been used in sweet cherry growing to increase yield and farm income in Turkey. This study was conducted to analyze the farm-level of pesticide use in sweet cherry growing in West Mediterranean region of Turkey. Data was collected from 89 growers using...
Dwarf and semidwarf apple trees planted at high density orchard are poorly illuminated when they come into full bearing. Insufficient illumination has adverse effect on apple red blush. Studies were carried out in years 2009–2013 in the Institute of Horticulture at Skierniewice. The object of the study were 12-year-old apple trees of ‘Jonagold’ and ‘Gala’. Trees were grafted on semi-dwarf M.26 rootstock,...
In recent years there has been an increasing interest in lawns and their appearance. Diseases affecting lawns, of which the causative agents can be various pathogens, reduce their quality. The study was conducted in two urban centers in the region of southeastern Poland – in the years 2006 and 2007 in Lublin and in 2007 in Zamość, both in sunny and in partly shaded places. The species composition...
There are seed propagated walnut (Juglans regia L.) populations with the vast genetic variation in different part of Turkey. There are also lots of monoecious and dichogamous genotypes in Turkey due to continuing sexual propagation. This study was conducted to determine genetic variability and to select superior walnut genotypes within seedling population grown in Kemah district in Eastern Anatolia...
Genetic and phenotypic stability of plants obtained via somatic embryogenesis may be disrupted. The reason can be an indirect regeneration of somatic embryos via callus or a high concentration of growth regulators added at the induction stage of somatic embryos. Somatic embryogenesis of ‘Lady Salmon’ (chimeric) and ‘Lady Vitroflora’ (non-chimeric) cultivars was induced on modified Murashige and Skoog...
In principle, in vitro propagation results in uniform batches of plants, which grow, flower and fruit normally. However, phenotypic changes often observed in the field performance of tissue culture-produced strawberry plants might affect their agronomic value. So, it is of utmost importance to assess the field performance of in vitro propagated plants to verify their fidelity to conventional propagated...
Phenolics are believed to inhibit the shoot formation in magnolia in vitro. The aim of this study was to determine the influence of sucrose, nitrogen salts and cytokinin concentrations on the phenolics content in relation to shoot formation in Magnolia × soulangiana ‘Coates’ in vitro. The results showed that the concentration and ratios of benzylaminopurine (BAP), sucrose and nitrogen salts in the...
Coriander is a herbal plant, whose fruit has medicinal and aromatic use. The field research described herein was conducted in 2006–2008, where a controlled, onefactor experiment was set up in a random block design with four replications. The experimental factor was nitrogen fertilization in doses of 20, 40, 60, 80 and 100 kg N·ha-1 and a control treatment (no nitrogen fertilization). The objective...
Hop (Humulus lupulus) is one of the basic raw materials employed in brewing. All hops secondary metabolites exhibit pronounced bioactive effects. Therefore beer is the most important source of hop bioactive compounds in the human diet. Xanthohumol is the major prenylated flavonoid occurred only in the hops plant. The aim of this study was to determine the content of selected biologically active compounds...
The quality of fresh herbs used mainly as food products, is dependent on a number of factors, including the agronomic and environmental ones. The pharmacopoeial material of summer savory is the whole or ground herb, which besides essential oil, contains many other biologically active compounds, such as tannins, carotenoids, flavonoids, and minerals. The aim of the study was to evaluate the yielding...
The knowledge on nematodes occurrence in Polish vineyards is poor. The surveys of the species from the rhizosphere of plants were conducted between 2013 and 2014 in 12 vineyards in the northwestern part of Poland. Recovery of the nematodes was made in two steps. First, through incubation of 50 g of the roots on sieve. Second, by centrifugation method using 200 g of soil. Nematodes obtained were killed...
A complete set of procedures comprising of the induction of haploid embryo development by pollination with irradiated pollen, embryo isolation and in vitro culture, haploid plant development, chromosome doubling by regeneration from leaf explants, acclimatization, self-pollination of DH plants and assessment of DH lines was performed in cucumber. Haploid and doubled haploid plants were obtained from...
