In the study, the effects of different training systems (Steep Leader: SL, Spanish Bush: SB and Vogel Central Leader: VCL) on quality properties and bioactive components of “0900 Ziraat” sweet cherry fruit (Prunus avium L.) were investigated. The size, color and firmness values of the fruit varied depending on training system. The largest fruit was obtained in the SB training system. The fruit on trees trained VCL and SB had higher firmness than the fruit of trees trained SL. The color values of the fruit of VCL were higher than the other systems, while the vitamin C content was lower. The lowest acidity and soluble solids content (SSC) were measured in fruit trees trained SL. The highest values for bioactive compounds as phenolics, flavonoids were measured in fruit of SL training system. In the sweet cherry fruit, the major phenolic acid was catechin. The catechin, rutin, caffeic acid, 4?hydroxybenzoic acid, 4?aminobenzoic acid and transferulic acid content of the fruit in the SL training system were higher than those of SB and VCL. As a result, it was revealed that there is an effect of the training system on fruit quality; SB training system had higher values in terms of fruit size, whereas in terms of bioactive compound content, SL training system had higher values.

The theoretical basis of the proposed technique is the cumulative variation of 137Cs measurements’ squared-differences between a reference and other sites. The change of the cumulative squared-differences with distance from the reference site is referred to as the point cumulative semivariogram (PCSV), which provides appropriate measure of cumulative similarity. Inspection of individual experimental PCSV provides local interpretation about the 137Cs radioactivity concentration around each site, whereas collective inspections provide possibility for grouping similar sites and hence identifying homogeneous sub-areas within the study area. It is also possible to prepare 137Cs radioactivity concentration maps based on pre-specified distances in each experimental PCSV, which lead to similarity levels. Such maps provide appreciation of 137Cs radioactivity concentration regional dependence in Keban Dam Lake, Turkey. Apart from the individual PCSV interpretations, the whole lake is divided into four distinctive classes. 相似文献

The growth and mortality rate of different size of mussels, Mytilus galloprovincialis, were compared in Mersin bay, Izmir. Mussel sampling was performed on a monthly basis over 1 year, together with hyrobiological parameters. Water temperature, salinity, chlorophyll a, total particulate matter (TPM) and particulate organic carbon (POC) were determined. Average chlorophyll a, TPM and POC values were 3.88±1.62 μg L−1, 13.12±3.68 mg L−1 and 252±121.89 μg L−1 respectively. Initial mean lengths of mussels for each size group were 10 mm (9.91±0.25 mm), 20 mm (20.14±0.29 mm), 30 mm (30.66±0.21 mm), 40 mm (40.14±0.21 mm), 50 mm (50.62±0.21 mm), 60 mm (59.77±0.21 mm) and 70 mm (69.47±0.62 mm). Maximum growth in length occurred during the spring–summer months. The annual length increments of mussel size groups were 46.22, 41.42, 30.3, 28.03, 20.63, 16.34 and 12.03 mm from small to large size groups respectively. Small mussels grew faster than large mussels and reached commercial size at the same time. Mortality was <5% for all groups at the end of the experiment. 相似文献
