Authors:Fatih Akkurt; Enes Yılmaz, Fatih Şen Abstract: In this study, it was aimed to impact the effect of different post-harvest treatments on the shelf life of banana fruits of 'Dwarf Cavendish' banana cultivar after storage and ripening. 1) Modified atmosphere packaging (MAP), 2) 1-methylcyclopropene (1-MCP) + MAP, 3) Three different treatments (MAP + ethylene absorbent (EA)) were applied and only those using macro-aperture PE packaging were considered as control. Banana fruits were stored at 13°C and 90% RH for 30 days. Quality analyses were performed on samples taken at 10-day intervals. After 30 days of storage, the banana fruits were ripened to the ripeness level of No.3 and quality changes were determined after 4 days of shelf life. The treatments significantly limited the color change, softening of the peel and flesh, increased total soluble solids (TSS), ethylene secretion and respiration rate, especially in the last period of storage compared to the control. Green bananas treated with 1-MCP + MAP showed the best results during storage, but ripening problems were experienced. MAP + EA treatment delayed the coloration of banana fruits, softening of the flesh and increases in the TSS content during shelf life. MAP + EA treatment gave the best results both in terms of storage of banana fruits at green maturity and their resistance after ripening. PubDate: Thu, 18 Jul 2024 00:00:00 +030
Authors:Mehmet Sedat Sevinç; İsmail Karaca Abstract: Accurately determining the effects of the age period when living things produce offspring on offspring provides an advantage for demographic studies. Knowing the effect of population age on biological parameters in the next generation is necessary for pest management against harmful species such as Mediterranean fruit fly, Ceratitis capitata. In this study, 5 equally spaced different groups were created based on the first spawning and last spawning times throughout the life of the C. capitata population. When the individuals forming the groups are examined, the periods spent by the first individual and the last individual before adult were 28-37, 23-55, 23-43, 20-33 and 18-21 days, respectively. Female-male ratios in the groups are as follows; It was determined as 34-13, 74-32, 56-35, 30-17, 8-6 individuals. Preoviposition-oviposition-postoviposition times of the groups, respectively; It was recorded as 16-12-5, 12-14-28, 7-16-33, 10-12-10 days, and no reproduction was observed in the fifth and last group. The numbers of female/male individuals of the offspring produced by the groups were respectively; 44/19, 101/34, 169/48, 366/79. The value was 0 because there was no reproduction in the fifth group. The population adult lifespans of the groups were respectively; It is 37, 54, 62, 36 and 20 days. Since the lifespan and reproductive status of individuals obtained from different age periods will vary, this should be taken into consideration when selecting individuals for studies on the management against C. capitata.

Authors:Kadir Uçgun; Hamza Gencer, Mesut Altındal, Bahar Türkeli Abstract: Temperate climate fruits are more sensitive to low irrigation water quality characteristics than many crop species. Since fruit trees occupy the soil for many years, irrigation water quality characteristics should be determined along with soil characteristics before orchard establishment. In this study, groundwater quality characteristics of Karaman Plain were determined and evaluated regarding apple cultivation. For this purpose, salinity (EC), pH, calcium (Ca+2), sodium (Na+), magnesium (Mg+2), potassium (K+), carbonate (CO3-2), bicarbonate (HCO3-), chlorine (Cl-) and boron (B) were analyzed in 30 water samples collected from deep wells at different locations. Alkalinity, sodium adsorption rate (SAR), residual sodium carbonate (RSC) and total hardness (TH) were calculated from the values obtained. All water samples were alkaline, C2 (67%) and C3 (33%) for salinity, hard (57%) and very hard (43%) for total hardness. All waters except 1 sampled well were found safe for B, and except 3 sampled wells were found safe for Cl-. There are no quality problems in terms of SAR and, RSC. Attention should be paid in all wells in terms of TH. The quality characteristics of irrigation water vary from well to well not from region to region. Therefore, each producer should know the quality characteristics of the water source they use and take precautions according to the water they use. PubDate: Thu, 18 Jul 2024 00:00:00 +030
Authors:Abdurrahim Bozkurt; Adem Yağcı, Davut Soner Akgül Abstract: Grape vine leaves can be used fresh or vine leaves preserve as traditional food. The aim of this study, obtain a new grape cultivar with prominent leaf characteristics. For the purpose, 446 genotypes obtained as a result of hybridization were used as plant material. In the study, the morphological suitability of the leaves of the genotypes for vine leaves preserve was determined during the development period. Genotypes were scored according to the Weighed Rating Method in terms of the examined criteria. According to the data obtained, the number of lobes of genotypes is 3 or 5; leaf thickness is ranged between 1.32 mm (NVL-34) and 0.244 mm (NRG-61); leaf keel thickness is between 0.53 mm (NVL-40) and 1.01 mm (Isabella); leaf hair density was determined to be low (3) and medium (5). 52 genotypes came into prominence according to the scores they received in terms of the examined characteristics. The scores of the genotypes varied between 940 and 1090. PubDate: Thu, 18 Jul 2024 00:00:00 +030
Authors:Burak Erdem Algül; Sema Acar, Beşire Bozkaya, Dilek Aslan, İbrahim Turan Abstract: Eşme quince variety has a very important commercial value for Türkiye, but low temperatures at the late harvest period, can cause flesh browning in the storage and this situation may limit the storage life of the Eşme quince variety. In this study, the effects of two different harvest dates one of which late harvest period and ascorbic acid applications (10 ppm and 20 ppm) were examined on fruit quality and fruit flesh browning of Eşme quince variety during a 30-day shelf life at 20 ºC and 60±5% relative humidity conditions. As a result of the study, there were significant changes in quality parameters such as weight loss (%), flesh firmness (N), acidity (%), starch index (1-8) and fruit skin greasiness (%) and fruit skin color (L*, hue, chroma) between Harvest I and Harvest II periods. In addition, although a 6.6% rate of fruit flesh browning was detected in the control fruit group of the 2nd harvest period, where ascorbic acid was not applied on the 30th day of the shelf life, no significant difference was detected between applications and harvest periods.

Authors:İsmet Tutar; Bahri Karlı Abstract: This study aimed to examine the farms producing grapes economically in the Baklan district of Denizli province. The research's primary data was collected using a survey of the farms producing grapes in the Baklan district. The data used in the study covers the 2021 production season. Grape yield per unit area (da) was determined as 685.65 kg in the examined farms. 57.08% of the production costs were variable, and 42.92% were fixed. The average production cost per decare in grape production was 1742.92 TL. The gross production value per decare was determined as 2536.27 TL. The average net profit was calculated at 1541.48 TL/da. The cost of producing one kilogram of grapes was 2.54 TL, and the selling price of one kg of grapes was 3.73 TL. On the other hand, the relative profit was 1.47 on average for the farms.
