The purpose of this research was to appreciate the impact of the synthetic cytokinin, well known as thidiazuron (TDZ) on seedless berry quality of cv. ‘Recel Uzümü’. Three concentration levels including 0, 5 and 10 mg/L were applied on the grapevines during different phenological stages of grapevine such as Time 1: beginning of berry stetting, Time 2: berries pepper corn size and Time 3: berries pea size. While TDZ application times had no impacts on cultivar characteristics, it was determined that the application doses of TDZ had major impacts on yield and quality components of cv. ‘Recel Uzümü’. 相似文献

The objective of this study was to determine the pharmacokinetics of tolfenamic acid (TA) following intravenous (IV) administration at doses of 2 and 4 mg/kg in goats. In this study, six healthy goats were used. TA was administered intravenously to each goat at 2 and 4 mg/kg doses in a cross-over pharmacokinetic design with a 15-day washout period. Plasma concentrations of TA were analyzed using the high performance liquid chromatography with ultraviolet detector, and pharmacokinetic parameters were assigned by noncompartmental analysis. Following IV administration at dose of 2 mg/kg, area under the concentration–time curve (AUC0−∞), elimination half-life (t1/2ʎz), total clearance (ClT) and volume of distribution at steady state (Vdss) were 6.64 ± 0.81 hr*µg/ml, 1.57 ± 0.14 hr, 0.30 ± 0.04 L h-1 kg-1 and 0.40 ± 0.05 L/kg, respectively. After the administration of TA at a dose of 4 mg/kg showed prolonged t1/2ʎz, increased dose-normalized AUC0-∞, and decreased ClT. In goats, TA at 4 mg/kg dose can be administered wider dose intervals compared to the 2 mg/kg dose. However, further studies are needed to determine the effect of different doses on the clinical efficacy of TA in goats. 相似文献

In some viticulture regions of the world, high temperature and irradiance can negatively affect the grapevine growth and grape quality. Particle film technology is a remarkable tool, leading to decrease in environmental stress conditions for grape production. In current study, leaf removal and kaolin particle film treatments were performed on east and west sides of grapevine’s canopy of cv. Muscat Hamburg and five different treatments were respectively evaluated: Control (C), leaf removal treatment from east side of grapevine’s canopy (LR-E), leaf removal treatment from east side of grapevine’s canopy plus kaolin particle film treatment (LR-E + K), leaf removal treatment from west side of grapevine’s canopy (LR-W), leaf removal treatment from west side of grapevine’s canopy plus kaolin particle film treatment (LR-W + K). In present research, the higher total phenolic compounds contents were measured in LR-W (2010.56?mg GAE/kg fw), LR-W + K (2006.42?mg GAE/kg fw), LR-E (1925.58?mg GAE/kg fw), LR-E + K (1913.15?mg GAE/kg fw) and C treatment (1851.46?mg GAE/kg fw). Furthermore, means of higher total anthocyanin content were obtained from LR-W (737.68?mg GAE/kg fw), LR-W + K (736.16?mg GAE/kg fw), LR-E (706.50?mg GAE/kg fw), LR-E + K (701.94?mg GAE/kg fw) and C treatment (679.12?mg GAE/kg fw). Consequently, it was observed that both LR-W and LR-W + K treatments had especially advantages in terms of increasing grape quality attributes of cv. Muscat Hamburg; were followed by LR-E and LR-E + K treatments. 相似文献

Eight different pepper genotypes inoculated by two different arbuscular mycorrhizal fungi (AMF) [Glomus intraradices (Gi) and Gigaspora margarita (Gm)] in a growth chamber experiment under normal seedling growing conditions were evaluated for seedling traits, colonization and relative mycorrhizal dependency (RMD). In general, inoculated plants had greater dry weights compared to non-inoculated plants. Five cultivars responded positively to inoculation with AM fungi and three responded negatively. A great variation in mycorrhizal colonization dependency was observed among the pepper genotypes, with the N52 genotype showing the highest RMD and the Karaisali genotype the lowest. RMD and dry weights of pepper genotypes were inversely correlated. 相似文献

The aim of this study was to determine the changes in the pharmacokinetics of meloxicam in goat kids who were castrated following the administration of xylazine. Six goat kids were used for the study. The study was performed in two periods according to a longitudinal study, with a 15-day washout period between periods. In the first period (Control group), 1 mg/kg meloxicam was administered by i.v. route to kids. In the second period (Castration group), the kids were sedated with 0.3 mg/kg xylazine and castration was performed following meloxicam administration. Plasma meloxicam concentration was analyzed using HPLC-UV, and pharmacokinetic parameters were calculated by noncompartmental model. In the control group following the administration of meloxicam, mean elimination half-life (t1/2ʎz), area under the concentration–time curve (AUC0−∞), total body clearance (ClT), and volume of distribution at steady-state (Vdss) were 13.50 ± 0.62 hr, 41.10 ± 2.86 hr µg/ml, 24.43 ± 1.75 ml hr−1 kg−1, and 0.45 ± 0.03 L/kg, respectively. In the castration group, the t1/2ʎz of meloxicam prolonged, AUC0−∞ increased, and ClT and Vdss decreased. In conclusion, the excretion of meloxicam from the body slowed and the t1/2ʎz was prolonged in the castrated goat kids following xylazine administration. However, there is a need to determine the pharmacodynamics of meloxicam in castrated goat kids. 相似文献

The pharmacokinetics of cefquinome (2 mg/kg every 24 hr for 5 days) was determined following intramuscular administration alone and co-administration with ketoprofen (3 mg/kg every 24 hr for 5 days) in goats. Six goats were used for the study. In the study, the crossover pharmacokinetics design with 20-day washout period was performed in two periods. Plasma concentrations of cefquinome were assayed using high-performance liquid chromatography by ultraviolet detection. The mean terminal elimination half-life (t1/2ʎz), area under the concentration–time curve (AUC0–24), peak concentration (Cmax), apparent volume of distribution (Vdarea/F), and total body clearance (CL/F) of cefquinome after the administration alone were 4.85 hr, 11.06 hr*µg/ml, 2.37 µg/mL, 1.23 L/kg, and 0.17 L/h/kg after the first dose, and 5.88 hr, 17.01 hr*µg/mL, 3.04 µg/mL, 0.95 L/kg, and 0.11 L/h/kg after the last dose. Ketoprofen significantly prolonged t1/2ʎz of cefquinome, increased AUC0–24 and Cmax, and decreased Vdarea/F and CL/F. Cefquinome exhibited low accumulation after the administration alone and in combination with ketoprofen. These results indicated that ketoprofen prolonged the elimination of cefquinome in goats. The 24-hr dosing intervals at 2 mg/kg dose of cefquinome, which co-administered with ketoprofen, may maintain T> minimum inhibitory concentration (MIC) values above 40% in the treatment of infections caused by susceptible pathogens with the MIC value of ≤0.75 μg/ml in goats with an inflammatory condition. 相似文献

Foliar sprayings of grapevines with different plant growth regulators or chemicals were evaluated for determining grape skin color and phenolic compounds content and enhancing table grape quality characteristics of cv. Red Globe in this study. Grape skin color is one of the most important quality factors for table grapes. Sometimes, it can be viewed difficulties in skin coloration of some red table grape cultivars grown in various grape growing regions of the world and poor skin coloration of red table grapes is a frequent trouble that reduces production efficiency. Despite the fact that it is utilized from some canopy management practices; plant growth regulators, chemicals with plant hormones and hormone-like compounds as active ingredients can be recently used for improving anthocyanin accumulation in growing of some table grape cultivars. In current study, nine different preharvest treatments were used for improving quality parameters of cv. Red Globe, including 1?Control (C), 2–300?mg/L Abscisic acid (ABA), 3–300?mg/L Ethephon (Eth), 4–30% Ethanol (EtOH), 5–300?mg/L ABA + 300?mg/L Eth, 6–300?mg/L ABA + 30% EtOH, 7–300?mg/L Eth + 30% EtOH, 8–300?mg/L ABA + 300?mg/L Eth + 30% EtOH and 9?Cluster tip cutting (CTC). Although the best results from total phenolic compounds content and total anthocyanin content of cv. Red Globe were obtained in CTC treatment in all preharvest treatments, Eth+ETOH treatment especially gave rise to the best results among the preharvest chemical treatments. 相似文献

Influence of Melatonin Treatments on Fruit Quality and Storage Life of Sweet Cherry cv. ‘Sweetheart’
The study was carried out to determine the effect of melatonin on quality and postharvest life of sweet cherries (Prunus avium L.) cv. ‘Sweetheart’ during storage. The fruits were dipped at different concentrations of melatonin (0, 250, 500 and 1000?µmol l?1 for 10?min) and distilled water as control. The changes of sweet cherries were assessed at 7?day intervals by evaluating the following quality parameters: firmness, soluble solids content, titratable acidity, respiration rate, color values (L* and chroma), ascorbic acid content, total anthocyanin content, total phenolic content, and antioxidant activity. The results showed that increasing the dose to 1000?µmol l?1 melatonin had a remarkable effect on maintaining the quality of sweet cherry. 1000?µmol l?1 and 500?µmol l?1 melatonin treatments significantly inhibited the decrease in firmness, ascorbic acid, total phenols, total anthocyanin, antioxidant content and reduced color changes and respiration rate. However, the total soluble solids content and titratable acidity of the fruit were not influenced by melatonin applications. These findings indicate that melatonin treatment may be effective in maintaining quality and bioactive compounds of sweet cherry fruit.
