Summary This study was conducted to determine the crop water stress index (CWSI) for potato (Solanum tuberosum L.) grown under furrow and drip irrigation methods and subjected to three different irrigation levels (100, 50 and 0% replenishment
of soil water depleted). The lower (non-stressed) and upper (stressed) baselines were determined empirically from measurements
of canopy temperatures, ambient air temperatures and vapor pressure deficit values. Tuber yield decreased when mean CWSI prior
to irrigation exceeded 0.68 in furrow and 0.81 in drip irrigation. The tuber yield was directly correlated with the seasonal
CWSI values and the linear equations for furrow and drip irrigation methods, Y = −45.82 CWSI + 50.69 and Y = −52.65 CWSI +
58.44, respectively, can be used for yield prediction. 相似文献

We examined the physical, physicochemical, and cooking properties of 91 kabuli chickpea landraces from Turkey, using two cultivars
(İnci and İzmir-92) as controls. All landraces were grown under the same agroclimatic conditions to eliminate variance caused
by genotype × environment interactions. There was high diversity among the landraces in the contents of protein (17.55–23.31%),
fat (4.45–6.11%), ash (2.54–3.41%), fiber (2.03–4.18%), starch (41.76–49.07%), moisture (6.39–10.57%), 100-seed weight (25.03–51.67 g),
hydration capacity (0.2585–0.6169 g/ml), swelling index (0.7207–1.1859), swelling capacity (0.15–0.32 ml seed−1), cooking time (33–72 min), and seed density (0.8450–1.4800 g/ml). Regional analysis of landraces showed significant differences
with respect to nutritional characteristics and cooking parameters. There were also significant relationships between various
seed quality and cooking parameters. Together, our results provide an initial step toward identification of chickpea landraces
that may be useful for development of high-quality chickpea cultivars. 相似文献

The aim of the present study was to determine the vitamin D status in cattle with malignant catarrhal fever (MCF). Twelve cattle diagnosed as MCF and 6 healthy cattle (controls) were used in the study. Serum 1,25-dihydroxyvitamin D(3) (1,25-D), 25-hydroxyvitamin D(3) (25-D), calcium, phosphorus and parathyroid hormone (PTH) levels were determined as 96.83 pg/ml, 30.0 ng/ml, 2.19 mmol/l, 1.57 mmol/l and 15.21 pg/ml in MCF group and 42.33 pg/ml, 37.0 ng/ml, 2.43 mmol/l, 1.96 mmol/l and 36.08 pg/ml in controls, respectively. Although serum 1,25-D level in the MCF group was increased (P<0.01), serum calcium (P<0.01) and PTH (P<0.05) levels were decreased compared to the controls. The results suggest that there might be an interaction between vitamin D status and MCF. 相似文献

This paper investigates club convergence in per capita income across 81 NUTS‐III regions in Turkey over the 1987–2017 period using the procedure suggested by Phillips and Sul. Based on a nonlinear factor model that allows for transitional heterogeneity, our econometric approach enables us to test the presence of convergence clusters and to examine their transitional behavior. We obtain strong evidence that there is no absolute or conditional convergence but convergence clubs across Turkish regions: five clubs in the first period covering 1987–2001 and six clubs in the second period covering 2004–2017. The geographical distribution of clubs suggests a clear separation between the eastern and the western regions of Turkey for both periods. While geography may be destiny, results from an ordered logit model reveal that initial income per capita, human capital, and total credits are the most important determinants of convergence clubs in Turkey. 相似文献

Tissue distribution of polyphenol oxidase (PPO) was studied in caramote prawn (Melicertus kerathurus) and jinga shrimp (Metapenaeus affinis) postmortem. Activity was analyzed in different tissues: the head (cephalothorax + carapace), carapace, exoskeleton of the abdomen, pereopods, and maxillipeds, individually. Based on the results, PPO activity of jinga shrimp was determined to be higher than caramote prawn during the research period. Partial tissue distribution showed that the highest activity was determined in carapace by using 70% ammonium sulfate fractions. Partial tissue distribution was also used to determine the spread of black spots. In addition, comparison between the PPO levels of caramote prawn and jinga shrimp was performed. The importance of these species is their economic value. However, there is no available data in the literature about caramote prawn and jinga shrimp. The determined data showed us that using antioxidant chemicals would be suitable for jinga shrimp. 相似文献

In the present study, 13 clinical cases of canine mammary adenocarcinoma were evaluated in order to understand the effect of Tarantula cubensis extract (TCE) on tumor tissue. Punch biopsies were taken from the tumors before treatment with TCE. Subcutaneous injections of TCE were administered three times at weekly intervals (3 mL per dog). Between days 7 and 10 after the third injection, the tumor masses were extirpated by complete unilateral mastectomy. Pre- and post-treatment tumor tissues were immunohistochemically assessed. The expression of B-cell lymphoma 2 (Bcl-2) was found to be higher in pre-treatment compared to post-treatment tissues (p < 0.01) whereas Ki-67 expression was lower in post-treatment tissues (p < 0.01). No significant differences in fibroblast growth factor or vascular endothelial growth factor expression were observed between pre- and post-treatment tissues (p > 0.05). The apoptotic index was determined to be low before treatment and increased during treatment. These results suggest that TCE may be effective for controlling the local growth of canine mammary adenocarcinoma by regulating apoptosis. 相似文献

Daily average SO2 concentrations were measured during August 1999–September 2000 period in the mountains around Izmir. Sampling devices to collect integrated daily SO2 samples were located at four different sites. These sites were Yamanlar Mountain in the north, Tekketepe height of Karabelen Mountain in the south, and two mountain villages (Kiziluzum and Bespinar) located east of Izmir. Samples were analyzed by using standard methods. Maximum daily SO2 concentrations up to 433 μg m-3 were found with the average values ranging between 75–135 μg m-3 per day at the four mountain stations. Annual mean values were above the threshold levels acceptable for the health of trees. It is concluded that such high SO2 pollution might have caused the noted decline in the forests.In order to decide the sources of such high levels of pollution on the forested mountains, trajectory analyses were carried out. Results obtained at Tekketepe station are given in this article and they point to the fractional contributions of dense industrial areas around Izmir, to the forested heights of Tekketepe. Local topography and location of industrial zones around the city are seen to have a strong effect on the deteriorated air quality over the mountains. The annual and seasonal averages and ten maximum daily measurements at the Tekketepe sampling site indicate that the highest contribution to the deterioration of air quality is associated with the northerly wind sectors. 相似文献
