The research aimed to assess the effects of methyl jasmonate (0.25, 0.5, and 1.0 mM MeJA) on weight loss and phytochemical compounds of kiwifruit (Actinidia deliciosa cv. `Hayward') throughout the cold storage and shelf life. Kiwifruits were stored at 0 ± 0.5 °C and 90 ± 5% RH for 180 days, and at 20 ± 1.0 °C and 80 ± 5% RH for 5 days in shelf life conditions. During cold storage, weight loss was significantly lower (P < 0.05) in 0.25 and 1.0 mM MeJA treatments than those of control and 0.5 mM MeJA treatments. The highest flesh firmness was determined in MeJA-treated fruits. In the latest measurement period of cold storage and shelf life, the lowest respiration rate was obtained from 0.5 and 1.0 mM MeJA treatments. MeJA-treated fruits had significantly higher hue angle at the end of cold storage. Generally, in shelf life analysis, acidity of MeJA-treated fruits was significantly lower than that of control fruits. At the end of cold storage, the highest vitamin C, total flavonoids, and antioxidant activity (DPPH) were measured in 1.0 mM MeJA treatment, whereas the highest total phenolics were detected in 0.25 mM MeJA treatment. Present findings revealed that MeJA could be used as an effective postharvest tool to maintain flesh firmness and phytochemical compounds of kiwifruits.

Turkish Journal of Agriculture and Forestry
This study was conducted to determine the effects of different drying methods and cold storage treatments on the postharvest quality and nutritional properties of P. ostreatus mushroom. In the study, six different treatments including natural drying, oven drying (60 °C), microwave drying (450 W), storage at -18 °C, 4 °C and 10 °C were evaluated. After drying and cold storage, pH value, ash, protein, color, total phenolic content, total flavonoid content, antioxidant activity and element contents in mushroom samples were detected. According to findings obtained from the study, drying and cold storage treatments significantly (p < 0.01) affected the postharvest quality and nutritional composition of P. ostreatus. The protein content, ash content, L* color value, total phenolic content, total flavonoid content, antioxidant activity and essential mineral contents such as potassium, magnesium, phosphorus, calcium, iron, zinc, and manganese of P. ostreatus decreased after drying and cold storage compared to the fresh mushroom sample. As a result, the best treatment was determined as storage at 4 °C in terms of protection the quality and nutritional value of P. ostreatus during postharvest storage. In addition, natural drying was the most effective treatment among drying methods, and it can be used successfully for longterm storage of this mushroom. However, it was concluded that microwave drying method was not suitable for the preservation of P. ostreatus since it caused significant nutrient and quality losses. The results of the present study will provide useful information about postharvest preservation and processing of P. ostreatus for researchers working on this issue.

Safflower is an underutilized and minor oilseed crop that received less attention from the scientific community compared to other oilseed crops like soybean and sunflower. Exploring the genetic basis associated with agronomic traits is crucial for markerassisted breeding of safflower. A genome-wide association study was conducted using a total of 12,232 DArTseq markers to identify the marker-trait association for important agronomic traits in an international safflower panel derived from 26 different geographical countries of the world. Statistically significant genotypic effects (p < 0.05) were observed across mean data of both locations (Pakistan and Turkey). Moderate to high heritability estimates were observed for the studied traits. Studied material showed higher performance for all traits except seeds per capitulum in Pakistan compared to Turkey. Phenotypic diversity for important agronomic traits, such as plant height (60.08 to 121.48 cm), capitula per plant (8.7 to 80.4), seeds per capitulum (15 to 42.05), and seed yield per plant (4.85 to 51.02 g), was illustrated. Seed yield per plant showed a highly significant and positive correlation with capitula per plant (0.4985***). Constellation plot analysis resulted in four groups, i.e. A, B, C, and D. Genotyping by sequencing resulted in 12,232 DArTseq markers being used for the investigation of marker-trait association through mixed linear model (Q + K) approach. DArT-38077549 showed significant association with capitula per plant, while two markers (DArT-22763576, DArT-22763253) were associated with plant height. A total of two markers (DArT-38079422, DArT-100043360) were associated with seeds per capitulum. A total of five DArTseq markers showed significant association with seed yield per plant and maximum variation was resulted by DArT-100004992. The results of this study provide a new insight to understand the genetic basis associated with agronomic traits in safflower. We envisage that significant markers identified through this investigation may be applicable in future safflower marker-assisted breeding programs.

The incidence rate of occupational accidents is an important indicator of occupational safety performance. The aim of this study was to classify the similarities and differences among 23 European Union (EU) countries along with Turkey in terms of various occupational accident evaluation criteria. This was achieved using the k-means clustering method on data from the forestry and logging sector between 2008 and 2017. The occupational accident assessment criteria used in the study include the nonfatal male accident incidence rate, the nonfatal female accident incidence rate, the total (male + female) nonfatal accident incidence rate, and the total (male + female) …

Decreasing availability of water and increasing consumption of it in recent years shows water management plans increase its value. Depending on water consumption in the current and previous years, it is important to predict water consumption in the coming years and make plans accordingly. Evaluation of the performance of water use in agriculture, identifying water resources that are most intensively used and prediction of the potential performance in the coming years have become increasingly important. Irrigation water management is of crucial importance for sustainable food security and needs to plan for saving water due to global warming and climate change …
