: Edible flowers are currently gaining popularity as the majority of the edible flower species have a nutritional profile that meets several dietary demands and the consumption of flowers as part of customary cuisine or alternative alchemy is reported in various cultures around the world. Pumpkin flowers are primarily consumed in some Asian and North American countries like India, China, Bangladesh, and Mexico, respectively. The pumpkin plant has served medicinally worldwide by treating wounds, cardiovascular disease, several types of cancers, gastrointestinal diseases, anemia, urinary tract infections and intestinal parasites, however, its flowers among the same line have also been therapeutically used to treat wounds and male infertility. These therapeutical effects are solely associated with their nutritional and phytochemical configuration. In this aspect, the present review focuses on providing a detailed overview of its morphological, physicochemical, thermal, and therapeutic properties within which, special emphasis is provided towards the mechanism followed by each bioactive component in treating the corresponding disease. The evaluation of therapeutic properties will help in understanding the pumpkin flower’s processing requirements. Its functional and nutritional potential can further help develop value-added products and supplements.

: Extreme climate events are expected to occur very frequently and intensively with climate change, and such extreme events can induce irreversible damage to plants and soils, as well as ecosystems. Accordingly, there is a need to understand the effects of extreme climate events on ecosystems. Here, we designed a temperature and precipitation manipulation system to simulate extreme climate events of heat, drought, and heavy rainfall. We constructed three soil surface temperature manipulation levels (control, 3 °C, and 6 °C increases) and three precipitation manipulation levels (control, drought, and heavy rainfall) with six replicates, and operated these from day of year (DOY) 195 to 233 in 2020. Infrared heaters increased the soil surface temperature during the extreme heat treatments. For precipitation manipulation, the automatic rainout shelter excluded ambient rainfall to produce drought conditions and an artificial rainfall simulator with spray nozzles produced heavy rainfall conditions. As a result, the soil surface temperature (°C ± one standard deviation) was higher in the 3 °C and 6 °C heated treatments than in the control by 2.7 ± 0.2 and 5.7 ± 0.5, respectively. The mean soil water content (vol. %) was 12.9 ± 8.6 in the drought treatment, 14.1 ± 7.8 in the control, and 16.1 ± 8.3 in the heavy rainfall treatment during the precipitation manipulation period. The results showed that the system design and operation were as expected. The designed system can be effectively utilized to investigate the responses of plants and soils to extreme climate events.

: Kombucha is a slightly sweet, acidic, carbonated, fermented beverage obtained by fermenting sugared tea ( Camellia sinesis ) with symbiotic bacteria. In the present study, kombucha was produced from black tea ( Camellia sinensis ), black grape ( Vitis labrusca ), black mulberry ( Morus nigra ), and rosehip ( Rosa canina ) fruits. Its physicochemical, microbiological, sensory properties and antimicrobial effects were investigated. During the fermentation, pH, Brix (%), viscosity, total antioxidant, and phenolic substance values decreased (p < 0.05). Total aerobic mesophilic bacteria (TAMB) and yeast/mold, Lactococcus/Streptococcus counts decreased, while the osmophilic yeast, acetic acid, and lactic acid bacterial counts increased (p < 0.05). The samples produced using black mulberry had the highest antibacterial activity (26.58 mm zone diameter), lowest minimum inhibitory concentration (MIC) (0.012 mg·L –1 ), and minimum bactericidal concentration (MBC) (0.008 mg·L –1 ) on Staphylococcus aureus . The highest antifungal activity was in the rosehip on Mucor racemosus (p < 0.05). The a* values increased during fermentation, while L* and b* values decreased. Based on the sensory analysis, black mulberry was the most preferred sample concerning all assessment criteria.

: In this study, the effects of a number of commonly used pesticides on the activity of the polyphenol oxidase (PPO) enzyme from pesticide-free and pesticide-applied ‘Jonagold’ apples were comparatively evaluated. Substrates 4-methylcatechol, pyrocatechol, pyrogallol and L-tyrosine were used to determine the substrate specificity of the PPO enzyme obtained from apple. According to the results, on the contrary, PPO enzyme from ‘Jonagold’ apple did not show any activity against L-tyrosine substrate which is a monophenolic substrate, the enzyme had high affinity against 4-methylcatechol, pyrocatechol and pyrogallol which are di and tri phenolic substrates. K m values of PPO enzyme obtained from pesticide-free apples against 4-methylcatechol, pyrocatechol, and pyrogallol substrates were determined as followed 0.27 mM, 2.27 mM, and 0.37 mM, respectively. V max values were found as 0.133 mM/min, 0.081 mM/min, and 0.051 mM/min. Optimum pH values were found to be 4.5 for 4-methylcatechol, 7.0 for pyrocatechol, and 7.5 for pyrogallol. Optimum temperature values were determined as 40 °C for 4-methylcatechol, 10 °C for pyrocatechol, and 50 °C for pyrogallol. K m values for PPO enzyme activity obtained from pesticide-treated apples against 4-methylcatechol, pyrocatechol, and pyrogallol substrates were 0.98 mM, 3.94 mM, and 0.37 mM, V max values were 0.08 mM/min, 0.02 mM/min, and 0.034 mM/min. Optimum pH values were found to be 7.0 for 4-methylcatechol and pyrocatechol and 7.5 for pyrogallol. Optimum temperature values were determined as 50 °C for 4-methylcatechol, 30 °C for pyrocatechol, and 40 °C for pyrogallol. Overall, the results showed that the PPO enzyme from pesticide-free apples had higher activity than pesticide-treated apples. The effects of metals and storage stability on PPO enzyme activity were also investigated. The results reveal that pesticide use affects PPO enzyme activity. The obtained data bring to light new pesticide functional features of great interest in the medicinal, agro-chemical and environmental circles.

: In this study, the effect of spermidine (SP) treatments at different doses after harvest on the changes in the pomological and biochemical contents of nectarine fruits was determined. The fruits were placed in cold storage (4 ± 0.5 °C and 90 ± 5% RH) for 30 days. Specific organic acids and phenolic compounds from biochemical compounds were analyzed by HPLC device. Weight loss and decay values, which are quality criteria of nectarine fruits, increased during storage compared to the harvest period. In this study, 1.0 mM SP application was found to be more successful in the preservation of visual quality (fruit pulp firmness and weight loss) properties during storage. At the end of the storage period (30th day), weight loss was determined as 3.27% in the control group and 1.84% in the 1.5 mM SP treatment. Fruit flesh firmness value, which is one of the important quality parameters affecting the storage life of fruits, was determined as 30.97 N in the control group and 37.06 N in 1.5 mM SP doze (30th day). Contrary to the acidity values, the total soluble solids content (TSS) and fruit juice pH values increased during storage. In this research, when the organic acid and phenolic compound contents are examined; it was determined that the dominant organic acid and phenolic compound in nectarine fruits were malic acid and chlorogenic acid, respectively. The malic acid ratio was found to be 4.89 g/kg in the control group and 6.66 g/kg in 1.5 mM SP treatment at the end of the 30-day storage period. Chlorogenic acid content was recorded as 6.86 mg/100g in the control group and 8.82 mg/100g in 1.5 mM SP application at the end of the storage period (30th day). In this study, it was determined that a 1.5 mM SP dose after harvest was effective on the biochemical contents of nectarine fruits and protected the fruits more during storage.
本研究测定了采后不同剂量亚精胺(SP)处理对油桃果实果理化成分变化的影响。在4±0.5°C、90±5% RH条件下冷藏30 d。用高效液相色谱法分析生化化合物中特定有机酸和酚类化合物。作为油桃果实质量指标的失重值和腐烂值在贮藏期比采收期有所增加。在本研究中，1.0 mM SP的应用被发现在贮藏过程中更成功地保存了视觉质量(果肉硬度和重量减轻)特性。贮藏期结束(第30天)，对照组体重下降3.27%，1.5 mM SP处理体重下降1.84%。果实果肉硬度值是影响果实贮藏寿命的重要品质参数之一，对照组为30.97 N, 1.5 mM SP睡眠(30 d)为37.06 N。与酸度值相反，总可溶性固形物含量(TSS)和果汁pH值在储存过程中增加。在本研究中，对有机酸和酚类化合物的含量进行了检测;结果表明，油桃果实中主要有机酸和酚类化合物分别为苹果酸和绿原酸。30 d贮藏结束时，对照组苹果酸含量为4.89 g/kg, 1.5 mM SP处理苹果酸含量为6.66 g/kg。贮藏结束(30 d)时，对照组绿原酸含量为6.86 mg/100g, 1.5 mM SP组绿原酸含量为8.82 mg/100g。本研究确定采后1.5 mM的SP对油桃果实的生化成分有较好的影响，在贮藏过程中对油桃果实的保护作用更强。
