In recent years, significant portions of the fresh fruits and vegetables produced worldwide have been decaying before reaching the consumer because of insufficient preservation after harvest. In this direction, we carried the study out to investigate the effect of gibberellic acid (GA₃) and 1-methyl cyclopropane (1-MCP) applications on phenolic compounds and organic acid contents of the strawberry fruits (cv. Albion) during shelf-life. Gibberellic acid treatments, which prepared in two different concentrations (50 and 100 ppm), were performed by spraying the leaves before harvest. 1-methyl cyclopropane applied after harvest. The results of the study showed a greater decrease in organic acids (except oxalic and succinic acid) in Gibberellic acid-applied fruits during shelf-life. Citric acid was recorded as the most abundant organic acid in the control group. In phenolic compounds, gallic acid (15.22 mg 100 g⁻¹) and ellagic acid (9.38 mg 100 g⁻¹) were recorded as the highest phenolic compounds on the third day. 1-MCP and GA₃ (50 ppm) + 1-MCP treatment reduced the breakdown of vitamin C during the shelf-life of strawberry fruits compared to the control group. As a result, phenolic compounds, vitamin C, and organic acids decreased during the shelf-life, and 1-MCP applications slowed down the breakdown of these compounds.

Essential oils (EOs) and organic acids (OAs) are promising feed additives with crucial roles in promoting animal health and performance. This study aimed to assess the combined effects of phytobiotics with organic acids (EOAs) in broiler diets for 39 days. A total of daily 300 male chicks were assigned to three groups, each containing 100 chicks with 5 replicates. The basal diet was supplemented with 0, 0.1, and 0.2% EOAs, respectively. EOAs supplementation did not significantly affect performance values. The villus height/crypt depth ratio in the jejunum and villus dimensions in the ileum showed improvement with EOAs. Dietary EOAs supplementation led to a reduction in the count of Enterobacteriaceae and an increase in Lactobacillus in the caecum. Serum IgA and IgG levels increased with EOAs. Ultimate load, yield load, and the levels of ash, calcium, phosphorus, zinc, and manganese in tibia and femur were higher at high levels of EOAs than in the other groups. In conclusion, the study suggests that 0.1% EOAs usage in diets could be a viable option for enhancing intestinal health, immunity, and bone mineralization as an alternative growth promoter, especially in commercial broiler production.

In this study, agro-morphological, sensory and biochemical characteristics of 23 plum genotypes belonging to Prunus spinosa L. subsp. dasyphylla (Schur) Domin growing wild in the West Black Sea Region in Turkey were investigated. Agro-morphological, sensory and biochemical properties of genotypes were highly different from each other. Principal component analysis was performed to determine the correlation between these properties and genotypes. The variation in the study was determined to be 63.5% in agro-morphological properties, 53.8% in organic acids and 46% in phenolic compounds. In terms of fruit weight, 14BLM08 genotype (38.42 g) was determined to be superior to other genotypes. The fruit firmness value, which is important in the storage of fruits, was recorded as the highest in the 14BLM14 genotype (9.07 kg/cm²). Chlorogenic acid was higher than the other phenolic compounds and the highest value was obtained in the 14BLM20 (11.45 mg/kg) genotype. It was recorded that the value of malic acid, which is the major organic acid of the plums, varied between 269.65–1294.64 mg/100 g. Genotypes showed diverse vitamin C content, and the highest value was found in the 14BLM18 genotype as 54.42 mg/100g. Each genotype showed superiority according to the type of traits, and thus breeders may have used these genotypes as the superior ones for specific plum breeding purposes. In addition, these genotypes could be satisfactorily used in domestication.

Tr en Bolu ekolojik koşullarında yetiştirilen Seascape çilek çeşidine ait meyve kaliteleri üzerine gibberelik asit uygulamasının etkisi araştırılmıştır. İki konsantrasyonda hazırlanan (50 ppm and 100 ppm) GA₃ uygulamasının meyve kalite parametreleri üzerindeki etkisi belirlenmiştir. SÇKM, pH, toplam asitlik ve meyve sertliği değerlerinin her iki uygulamada da istatistiksel olarak etkilenmediği ve uygulamalar arasında fark bulunmadığı tespit edilmiştir. Diğer kalite parametrelerine ait değerlerin ise en yüksek 50 ppm uygulamasında elde edildiği görülmüştür. Yapılan araştırmada SÇKM ve sertlik değerleri 100 ppm'lik konsantrasyonda sırasıyla 6.67 briks° ve 1.31 kg/cm² olarak belirlenmiştir. Kontrol meyveleri en yüksek pH değerine (4.08) sahipken, 50 ppm GA₃ uygulanan meyveler en düşük pH değerine sahip olduğu belirlenmiştir. Buna ek olarak, en yüksek meyve ağırlığı (46.01 g) ve meyve asitliği (% 1.11), 50 ppm GA₃'ün uygulamasında elde edilmiştir. Ayrıca GA₃ uygulamasının aroma, tat ve meyve suyu değerlerinde önemli bir değişime neden olmadığı görülmüştür. In the study, the effect of gibberellic acid treatments on fruit quality of strawberry cv. Seascape grown in Bolu ecological conditions was examined. The fruit quality parameters were identified under the application of two concentration of GA₃ (50 ppm and 100 ppm). It was determined that the values of SSC, pH, TA and fruit hardness were not statistically affected by both GA₃ applications. The highest values related fruit weight and size were obtained at 50 ppm GA₃ application. The SCC and firmness values were determined as 6.67 brix° and 1.31 kg/cm² in 100 ppm concentration, respectively. The fruits treated with 50 ppm GA₃ had lower pH than those treated 100 ppm GA₃ and control. In addition, the highest fruit weight (46.01 g) and fruit acidity (1.11%) were obtained at the application of 50 ppm GA₃. It was also found that the GA₃ application did not cause a significant change in the flavor, taste and juice values.
