Garden perennials are a source of floristry material produced in field or under covers. A perennial producing long, leafy shoots, which in flower arrangements might successfully substitute fern or palm leaves, is Polygonatum multiflorum. The variety characterizing with decorative white margined leaves is ‘Variegatum’. To improve their quality, the growth stimulator Actisil Hydro Plus, which contains...
The tripartite associations of arbuscular mycorrhizal fungi (AMF), rhizobia and legumes play a vital role in preserving and even restoring fertility of poor and eroded soils. The present study attempted to quantify relationship between legumes and symbiotic microorganisms (rhizobia and mycorrhizal fungi) by describing the mycorrhizal status and the occurrence of nodualtion of legumes growing in different...
For its specific physical and physicochemical properties, the water treated with low-frequency low-pressure glow plasma (GPTW) affects the growth of plants and enhances the phytoavalibility of selenium (Se) ions from the nutrient solution. The basic biometric and physiological parameters of cucumber and the uptake of Se ions applied as selenate (Na2SeO4) from the nutrient solution prepared using GPTW...
This study was conducted to investigate the effects of pre-harvest Harpin treatments and post-harvest MAP treatments on fruit quality attributes and bioactive compounds of ‘0900 Ziraat’ cherry cultivar throughout cold storage and shelf life of the fruits. Weight loss and decay ratios were significantly reduced with Harpin and MAP treatments. In general, lower L* and chroma values were measured in...
Indian jujube (Zizyphus mauritiana Lamk.) is mostly cultivated in tropical and sub-tropical regions of the world. Many native and exotic jujube cultivars are grown for fruit production in Pakistan. However, little research work has been conducted on various aspects of jujube i.e. morphological and biochemical characterization of available germplasm. Therefore, fruits of thirteen genotypes were collected...
The study aimed to determine the most appropriate irrigation scheduling for mini-type cucumber plants grown as a spring-summer cycle crop. The research was conducted in a greenhouse structure in the fields of the Research Institute in Kirklareli. Marathon cucumber plants were used as the plant material in the trials. The split plot design experimental layout in 3 replications was used in the research...
Endophytes produce a wide range of compounds with high application potential, mainly in medicine and agriculture. In this study, we test the hypothesis that endophytic bacteria produce indole-3-acetic acid (IAA), have positive influence on plant root development and are possible to application as plant-growth promoters. Endophytic bacteria were isolated from 3 native growing plant species: Chelidonium...
In this study, effects of two stress inhibitors (particle film – PF and dicarboxylic acid – DA) on aroma composition of Beauty Seedless and Tekirdag Seedless grape cultivars were investigated. Analysis of the aroma components was carried out using solid-phase microextraction technique with gas chromatography (GC) and mass spectrometry (MS). A total of 36 and 24 aroma compounds were identified in Beauty...
In this study, random amplified polymorphic DNA (RAPD) and simple sequence repeat (SSR) loci were used to investigate the genetic relationships in a group of 22 raspberry accessions. Fifteen RAPD primers generated a total of 324 bands, among them 94.1% were polymorphic. From ten used SSR pairs of primers, nine generated only polymorphic bands and the average percentage of polymorphism was 97.8%. Genetic...
Double-haploidization (DH) is one of the favorable techniques to obtain 100% pure double haploid plants (DH’s) for generating the new F1 cultivars in a short time. The fecundity of this technique depends on the high quantity of haploids and also fertile DH’s. However, there are no comprehensive reports on the chromosome doubling and fertility (fruit and seed-set) of winter squash and pumpkin haploids,...
Sclerotinia scletoriorum (Lib.) de Bary is a serious pathogen of carrots that can cause up to 50% losses of stored roots. Fungicides were found not to be completely effective for its control and due to residues they are not permitted for the use in storage. Biological control agents such as Pythium oligandrum may be a chance. The aim of research was to determine the level of carrot infection with...
The objective of the study was to develop effective chemical methods of protection of Gerbera jamesonii against Phytophthora cryptogea with consideration of the way of their application. In laboratory conditions, the activity of 7 tested agents was evaluated based on growth of P. cryptogea on a medium containing fungicides, and size of necrosis in inoculated gerbera leaf blades. In greenhouse tests,...
The yield quantity and quality depend on genetic factors, cultivation system and environmental conditions. Growth conditions can be improved by mulching the soil with plastic and biodegradable materials. A 2-factor experiment was conducted in 2011–2013 in the Wroclaw University of Environmental and Life Sciences. The method of random blocks in 3 repetitions was applied. The aim of the study was to...
The study aimed to investigate the effects of commercially available AMF inoculate (a mixture of Rhizophagus intraradices, Claroideoglomus etunicatum, Funneliformis mossea, Funneliformis geosporum, Rhizophagus clarus) and plant growth promoting bacteria (Rhizobium leguminosarum and Burkholderia sp.), either supplied individually or in combination with each other, on growth, root morphology and nutrient...
Plants absorb light energy for photosynthesis, and some amount of potentially damaging range of solar radiation, ultraviolet B. It accounts for less than 0.5% of the total solar radiation and the ambient current level of UV-B during the growth season provide 10 kJ·m–2 energy per day on the Earth’s surface. In the field conditions, increased UV-B radiation is often accompanied by drought, but negative...
Malus floribunda coccinella is a landscape tree that is generally planted for its pinky flowers and small reddish fruits. The red-fleshed fruits, called crab apples, are rich in anthocyanins and are assumed as an environmental pollution material during the fruit bearing season. The aims of this research were to determine the organic acids, sugars, sugar:acid ratio, color, phenolic compounds and antioxidant...
In the present study, using ultrasonic irradiations, a novel nano-sized iron complex has been prepared from aminolevulinic acid and iron(III) nitrate under greenhouse conditions. The obtained Fe nano-sized complex has been characterized by two methods of Fourier-transform infrared spectroscopy (FTIR) and EDX spectra (Energy-dispersive X-ray spectroscopy). Also, the morphology and size of the nano-complex...
Khatouni melons are a major horticultural crop that is produced mainly in semi arid and arid regions of Iran. The plant root characteristics can significantly affect many growth traits, including water and nutrients uptake under such dry conditions. On the other hand, nutrient elements concentration and their ratios can strongly affect the root morphophysiological and structure. In this study, the...
In this study, we compared the compositions, antimicrobial and potential antioxidant activities of essential oils of two Thymus endemic, wild-growing species – T. malyi Ronninger and T. lykae Degen et Jav. No information about its composition and biological activities of oils has been reported to the present day. Forty three compounds were identified from T. malyi and major component was α-pinene...
The mode of inheritance and the degree of phenotypic correlation between some more important agronomic traits in two offsprings obtained by direct and reciprocal crossing of cultivars ‘Smederevka’ and ‘Gewurztraminer’ were investigated in this study. In 62 genotypes from direct crossing (Smederevka × Gewurztraminer) and 66 genotypes from reciprocal crossing (Gewurztraminer × Smederevka), the traits...
