Kalanchoë daigremontiana leaves contain phenolic compounds, which are one of the determinants of plant therapeutic properties. Light and scanning electron microscopes were used to analyse the structure of leaves. The main aims of the study included the analysis of the anatomy of leaves, localisation of phenolic compounds, and identification of phenolic acids. The thickness of the amphistomatic leaf...
In recent times, pomegranate has been one of Turkey’s most important commercial fruit crops for consumption and export. In this study, the chemical composition of pomegranate (Punica granatum L.) fruits grown in the central area of Bitlis province (Eastern Turkey) was investigated. For this purpose, total phenolic content, ascorbic acid content, total anthocyanin and antioxidant activity and minerals...
Astragalus nitidiflorus is an endangered legume endemic to the southeast of the Iberian Peninsula. This species develops symbiotic relationships with N-fixing bacteria. However, the problem of isolating its rhizobia has not been solved. Because poor N fixation in plants can be corrected by fertilization, the effect of N-P-K fertilizers on growth, leaf chlorophyll and mineral ions was studied. Plants...
The research objective was to determine and compare dry matter, crude protein, mineral elements (total), dietary fiber, easily hydrolysable sugars, vitamin C, and minerals (K, Na, Mg, Cu) as well as the content of epicatechin and phenolic acids (homovanillic, chlorogenic, caffeic, coumaric, and ferulic) in the flesh and peel of ‘Šampion’ cv. apples grafted on 4 different rootstocks types: M.26, P2,...
Water shortage is a major problem that limits growth and productivity of plants in arid and semi-arid regions. Protecting plants from adverse environmental conditions by using simple methods could be of great value under these conditions. In the present study, we examined water status and drought tolerance of snap bean, a drought-sensitive plant, and Jerusalem artichoke, a relatively drought tolerant...
Effects of prohexadione-calcium (ProCa, 125 and 250 mgL–1) and ProCa + ammonium sulfate (AMS, 500 mgL–1) treatments on vegetative characteristics (shoot growth, branch diameter, trunk cross-sectional area (TCSA), canopy volume, number of flower per cm2, number of fruits per cm2) and quality parameters (fruit size, flesh firmness, color, titratable acidity and soluble solids content (SSC)) of ‘0900...
This study evaluated the effect of Pseudomonas strains and arbuscular mycorrhiza fungi (AMF) in enhancing strawberry yield and phenolic and antioxidant capacity on a phosphorus (P) deficient calcareous soil. The experiments were conducted in three replicates with six treatments (four Pseudomonas strains, AMF and control) and three rates of P-fertilizer (0, 75, 150 kg P ha–1). Application of higher...
Different nutrient media (MS [Murashige and Skoog 1962]; QL [Quoirin and Lepoivre 1977] and WPM [Lloyd and McCown 1980]); plant growth regulators BA (benzil adenin), GA3 (gibberellic acid), IBA (indole-3-butyric-acid), NAA (naftalen acedic acid); and sucrose concentrations were studied to determine the in vitro culture effects on healthier and faster seedling development from mature lentisk (Pistacia...
The aim of the study was to evaluate the effect of HPS and LED assimilation lighting and LED interlighting on the yielding and as cucumber fruit quality in autumn cultivation cycle. The possibilities of increasing the density of plants due to the use of LED technology were also assessed. The study was conducted in three compartments: I with HPS top light only; II with top light HPS + 2 line LED interlight,...
Bio-stimulants are in excessive demand for the sustainable production of floriculture crops. The current investigation was designed to find out the effect of naturally occurring growth stimulant moringa leaf extract (MLE) on the growth, flowering, post-harvest life and corm production of two gladiolus cultivars (cvs.) ‘Rose Supreme’ and ‘White Prosperity’. The research trial was laid out in the factorial...
Globally, the application of rootstocks for grapevine cultivation has been a standard, while in the northern regions, like in Poland where the viticulture tradition is relatively short, the selection of the most suitable rootstock types requires multi-year observation and research. The objective of the present study was to assess the effect of six following rootstock types: ‘101-14 Mgt’, ‘161-49C’,...
Nutrition of grapevines is very sensitive issue in vineyards. Soil quality is very important matter for growth and quality in vine growing. Rootstocks affect the growth and productivity of grapevine as well as increase or decrease of the nutrient uptake. The present study was conducted to determine the phenological changes of nutrient uptakes in 10 years ‘Trakya İlkeren’ grape variety (Vitis vinifera...
Colletotrichum coccodes (Wallr.) Hughes has been recognized as one of casual agents of anthracnose roots pepper in south-eastern Poland. During 2007–2012 the species was isolated from roots of sweet pepper (Capsicum annuum L.) cultivated in the field. The purpose of the study was morphological characterization and biotic activity of C. coccodes isolates. Five randomly chosen isolates from fungus population...
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...
