Effects of different types and levels of zinc sulphate applications in vineyards (Vitis vinifera L.) in a semi-arid environment

WOS: 000242775700078The present study was carried out to determine the effect of soil and foliar applications of different rates of zinc in the vicinity of Alasehir, one of the most important viticultural centres in the Western Aegean Region where the round seedless grape cultivar (Vitis vinifera L.) is widely grown, on productivity and some chemical quality characteristics as well as leaf primary and secondary elements. Zinc was applied to soil and foliage as ZnSO4 center dot 7H(2)O in the experiment with four replications. One soil application (0-15-30-45 g ZnSO4 center dot 7H(2)O/vine) in addition to foliar application replicated three times (0.0-0.025-0.050-0.10% Zn). Both soil and foliar zinc sulphate (ZnSO4 center dot 7H(2)O) applications increased the amount of fresh grapes per vine. The highest yield was observed at 30 g ZnSO4 center dot 7H(2)O level per vine in soil application and at the rate of 0.05% Zn in foliar application. Zinc sulphate produced a significant positive effect on the contents of primary and secondary elements (N, P, K, Ca, Mg, Fe, Zn, Mn, Cu) of the leaf (lamina and petiole) with the exception of the leaf petiole manganese content in the soil application and the leaf petiole copper content in the foliar application. Soil and foliar applications of zinc sulphate negatively affected the firmness of the berry flesh. The only fruit quality characteristic positively affected by soil and foliar applications of zinc sulphate was the amount of total soluble solids. Despite the fact that the soil application of zinc sulphate did not have any significant effect on some sugar fractions, the foliar application increased only the fructose and a-glucose significantly. In conclusion, it was established that foliar application of zinc sulphate was slightly more effective on yield as well as some quality characteristics as compared to soil application. Therefore, it was concluded that foliar application could be preferred as it is more economical and easier to apply

QUALITY PARAMETERS OF VINEYARD IRRIGATION WATER IN A SEMI-ARID REGION: THE PLAIN OF ALASEHIR, TURKEY

WOS: 000349805300017Production of seedless raisins is extremely important in Aegean Region in Turkey. The Plain of Alasehir in province of Manisa in Aegean Region is extremely important for seedless raisin production since 25% of the seedless raisin has been grown in this area. The irrigation water samples were collected from 13 different water distribution locations in the Plain of Alasehir. Results showed that pH and EC (electrical conductivity) values were in a reasonable range except EC levels from two locations were slightly high. The vineyard irrigation water in the region was classified as type of C3S1. It was suggested that, the salt content might be monitored continuously since salinity might increase in the soil through the end of the irrigation season. The most common cations were Ca++ and Mg++, and anion was HCO3-. Trace elements and heavy metals were under the risk limits except Mn was high in three locations. Boron was high in nine sampling locations. Overall, irrigation waters in the Plain of Alasehir were suitable for vineyard irrigation as long as the contents of boron and salinity were continuously monitored

Prolonged Tp-e Interval and Tp-e/QT Ratio in Children with Mitral Valve Prolapse

Although it is considered to be a benign condition, previous studies have shown that a subset of patients with mitral valve prolapse (MVP) may be at risk of ventricular arrhythmia and sudden cardiac death (SCD). Previous studies have suggested that the interval between the peak and the end of the T wave (Tp-e) can be used as a marker for the transmural dispersion of repolarization. Increased Tp-e interval and Tp-e/QT ratio are associated with ventricular arrhythmias and SCD. The aim of this study was to assess alterations in ventricular repolarization by using the Tp-e interval and Tp-e/QT ratio in children with MVP and to investigate their relationships with the degree of valvular regurgitation. This study prospectively investigated 110 children with MVP and 107 age- and sex-matched healthy control subjects. Tp-e interval, Tp-e/QT ratio, and QT and QTc dispersions were measured from a 12-lead electrocardiogram and compared between groups. QT and QTc dispersions, Tp-e interval, and Tp-e/QTc ratio were found to be significantly higher in patients with MVP. A positive correlation was found between Tp-e/QTc ratio and increase in the degree of mitral regurgitation (MR) (p 0.05). Individuals with MVP may be more prone to ventricular arrhythmias due to prolonged QTd, QTcd, and Tp-e interval and increased Tp-e/QT and Tp-e/QTc ratios. Therefore, due to their longer life expectancy, children with MVP should be followed up on regarding life-threatening arrhythmias

Do male and female patients with chronic neck pain really have different health-related physical fitness, depression, anxiety and quality of life parameters?

AimThe purpose of this study was to investigate whole body physical fitness parameters such as maximal aerobic capacity (VO(2)max), muscle strength, trunk flexibility, daily physical activity, pulmonary function, body composition, anxiety and depression, as well as other disease-related changes in patients with chronic neck pain (CNP), and to compare them with healthy controls

Echocardiographic evaluation of cardiac functions in newborns of mildly preeclamptic pregnant women within postnatal 24-48 hours

The aim of this study is to detect preeclampsia-related cardiac dysfunction within 24-48 hours of delivery in newborns born from preeclamptic mothers. Forty newborns from mildly preeclamptic mothers formed the study group and the control group was formed by 40 healthy newborns. Cardiac function for the groups were evaluated using conventional echocardiography and myocardial performance index (MPI) within the first 24-48hours of their lifetime and the results of both groups were compared. A significant difference between the groups was observed especially in the PW Doppler MPI measurements (the left ventricle MPI 0.37 +/- 0.09 and 0.26 +/- 0.11, p<.001; the right ventricle MPI 0.29 +/- 0.08 and 0.26 +/- 0.07, p<.035) for the control group and the study group. Elongation in the left and right ventricle MPI was detected to be more significant in terms of comparing systolic and diastolic functions to determine preeclampsia-related cardiac injury in newborns from preeclamptic mothers within the first 24-48hours of their lifetime
