Nowadays increasing attention has been focused on polyphenolic compounds as the main representants of antioxidants in horticultural crops including fruits. The edible honeysuckle has an unique position among lesser known fruits due to its high level of antioxidants. In the present study we determined polyphenolic profile and antioxidant capacity of four Russian cultivars of edible honeysuckle including ‘Gerda 25’, ‘Amfora’, ‘Morena’, ‘Lipnicka’, which found together in a single location in Mendel University in Brno, The Czech Republic. Polyphenolic compounds were detected by high performance liquid chromatography coupled with electrochemical detector (HPLC-ED). The antioxidant capacity was measured by DPPH test. According to the results there were differences among cultivars in terms of polyphenolic content and antioxidant activity and Lonicera kamtschatica ‘Gerda 25’ were found to be possessed the highest content of phenolic compounds corresponding to the highest value of antioxidant activity. 相似文献

Breeding for higher levels of health-promoting components are among the priorities for many fruit crops. Such an approach requires breeding material displaying great variations in the trait to be improved. Commercial sweet cherry cultivars demonstrate only limited variability in fruit antioxidant parameters and hence this study was carried out to characterize some Ukrainian sweet cherry cultivars for their antioxidant and antiradical capacity and total phenolic and anthocyanin contents. Ukrainian cultivars had significantly higher ferric reducing antioxidant power and total phenolic contents compared with commercial cultivars. Levels of all four parameters varied considerably in the Ukrainian germplasm, with some cultivars having outstanding values. A total of eight different self-incompatibility genotypes were assigned to the 14 accessions tested. Assigning cultivars to the appropriate incompatibility groups allowed the design of parental combinations which may result in new genotypes with enhanced functional properties and other valuable fruit traits. Based on the S-genotypes, parental combinations were proposed to ensure 50 or 100 % self-compatible seedlings in the offspring population. The most perspective Ukrainian cultivars like ‘Dagestanka’ and ‘Kodrinskaya’ also had reasonable fruit weight (over 8 g), high flesh to pit ratio (approx. 18) and soluble solid contents (over 16 %). Our results demonstrated that adequate variation is available in Ukrainian germplasm for improving fruit health benefits in sweet cherry through directed hybridizations. 相似文献

Carob (Ceratonia siliqua L.) is natively grown in the coastal areas of the Aegean and Mediterranean region in Turkey. The main carob growing areas (Mediterranean and Aegean) were surveyed and a total 70 promising wild and grafted carob genotypes were selected based on physical and chemical pod properties. Preliminary results showed that Turkey has very rich carob genetic resources containing considerable variations for most of the pod traits. In general, wild carob had smaller pods than the grafted ones. Pod mass ranged from 29.16 g to 120.28 g in the wild genotypes and 71.71 g to 147.91 g in the grafted genotypes with an average 107.61 g for the grafted and 63.72 g for the wild genotypes. The average pod dimensions (width, length and thickness) were 18.16 mm, 16.18 cm and 6.42 mm for the wild genotypes and 21.79 mm, 16.91 cm and 8.79 mm for the grafted genotypes. The average soluble solid content ranged from 59.42% in the wild and 64.06% in the grafted genotypes. The average total acidity of the wild and grafted genotypes was similar (0.78%). The pod traits of the wild genotypes differ significantly from those of the grafted genotypes, and the wild genotypes showed higher variations in these traits compared to the grafted genotypes. 相似文献

This study was conducted to examine the effect of inoculation of plant growth-promotion Rhizobacteria (PGPR) on phenological data, total yield and fruit quality characteristics of strawberry (Fragaria x ananassa Duch) cv. ‘Fern’ during 2006 and 2007. All bacterial root inoculations significantly increased yield per plant (1.98–20.85%), average fruit weight (3.05–19.26%) and first quality fruit ratio (10.30–32.05%) compared to control, whereas the bacterial inoculations did not affect leaf area, first flowering and harvest dates in strawberry cv. ‘Fern’. The bacteria also increased soluble solid content (SSC) and vitamin C in strawberry cv. ‘Fern’. The vitamin C contents of fruits ranged from 47.41 mg 100 g?1 (control) to 53.88 mg 100 g?1 (RC05), while SSC values varied between 10.16% (control) and 12.83% (RC01). Results of this study show that RC19 (Bacillus simplex), RC05 (Paenibacillus polymyxa), and RC23 (Bacillus spp.) have the potential to increase the yield and growth of strawberries. 相似文献

Spectrophotometric, morphologic and dielectric properties of polyacrylonitrile (PAN) composite films in the presence of pyrrole
derivatives were reported in this paper. The composite films were fabricated by oxidative polymerization of pyrrole (Py),
N-methyl pyrrole (NMPy) and N-phenyl pyrrole (NPhPy) by cerium(IV) on polyacrylonitrile matrix. The effect of temperature
on the dielectric properties was studied in the frequency range from 0.05 Hz up to 10 MHz and in the temperature range from
0 °C up to 250 °C. Conductivity was increased with temperature due to increase of the mobility of charge carriers in the composite
films. By increasing the temperature, the dipoles become free and respond to the applied electric field in composite structure;
thus, the polarization and dielectric constant increases. PNPhPy-PAN composite films exhibited the highest dielectric constant,
AC conductivity and tan delta. 相似文献

This work reports on the newly synthesized 9-tosyl-9H-carbazole (TsCz) monomer. Capacitive properties of the electrochemically grown homopolymer, poly(TsCz) film on carbon fibre
microelectrode (CFME), are characterised by cyclic voltammetry (CV), Fourier transform infrared reflectance-attenuated total
reflection spectroscopy (FTIR-ATR), scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). Different
monomer concentrations (1, 3 and 10 mM) were used for electrodeposition in 0.1 M sodium perchlorate (NaClO4)/acetonitrile (ACN) solution. The capacitive behaviour of modified CFMEs was defined via Nyquist, Bode-magnitude and Bode-phase
plots. An equivalent electrical circuit R(CR)(QR)(CR) for different concentrations of poly(TsCz)/CFME was proposed and experimental
data were simulated to obtain the numerical values of the circuit components. The Nyquist plot for poly(TsCz) shows the highest
specific capacitance (50.0 mF cm−2) at frequency of 0.01 Hz in the initial monomer concentration of 10 mM. 相似文献
