Chlorophyll fluorescence (CF), growth parameters, phytochemical contents [proline, chlorophyll, ascorbic acid, total phenol content (TPC), flavonoid (TFC)], and antioxidant activities were investigated in lettuce (Lactuca sativa L.) seedlings grown under different sodium chloride (NaCl) concentrations (0, 50, 100, 200, 300, 400 mM) a controlled environment for eight days. The parameters evaluated at two days intervals. Almost of the CF as well phytochemicals significantly affected by both...

To evaluate the ripening-dependent changes in phytonutrients, seven commercial cultivars (two general and five cherry) of tomatoes were cultivated under greenhouse conditions. Fruits harvested at breaker, turning, pink, light red, red stages each cultivar, antioxidant contents, color attributes, activities measured. During ripening process, lycopene content increased from breaker to stage, while lutein displayed reverse accumulation pattern, with higher values during stage. In contrast,...

Chlorophyll fluorescence ( CF ) is used to measure the physiological status of plants affected by biotic and abiotic stresses. Therefore, we aimed identify changes in parameters grafted watermelon seedlings exposed salt, drought, high low temperatures. Grafted at true three-leaf stage were subjected salinity levels (0, 50, 100, 150, 200 mM) temperature [low (8°C), moderate (24°C), (40°C)] stresses for 12 days under controlled environmental conditions independently. Eight measured 2-day...

Glucosinolates (GLS) are secondary metabolites occurring in cruciferous species. These compounds important for plant defense, human health, and the characteristic flavor of Brassica vegetables. In this study, GLS tubers from a collection 48 turnip ( rapa ) accessions different geographic origin were analyzed. Two methods used: desulfo analyzed by high-performance liquid chromatography with photodiode array detector, intact accurate mass chromatography-mass spectrometry. For most GLS, signals...

Individual glucosinolates (GSLs) were assessed to select cabbage genotypes for a potential breeding program. One hundred forty-six from different origins grown in an open field March June 2019; the heads used GSL analyses. Seven aliphatics [glucoiberin (GIB), progoitrin (PRO), epi-progoitrin (EPI), sinigrin (SIN), glucoraphanin (GRA), glucoerucin (GER) and gluconapin (GNA)], one aromatic [gluconasturtiin (GNS)] four indolyl GSLs [glucobrassicin (GBS), 4-hydroxyglucobrassicin (4HGBS),...

Thirty three-day-old paprika (Capsicum annuum L.) seedlings were grown under different temperature conditions (low: 10°C, moderate: 25°C, and high: 35°C) in a closed plant production system for 32 days their chlorophyll (Chl) fluorescence growth parameters, Chl proline contents measured at 0, 1, 2, 4, 8, 16, 24, after the initiation of treatment. Minimal (F0) sharply increased from 8 continued until end experimental period all three treatments, with highest increase low condition. Maximum...

Three commercial cultivars and eleven inbred broccoli lines were used to investigate the glucosinolate (GSL) profile, hydrolysate nitrile contents, formation rate. Glucobrassicin (BRA) glucoraphanin (GRA) most dominant GSLs in all lines. The 5405 5406 exhibited highest total GSL content (18.39 22.97 μmol·g−1 DW, respectively). Altogether, five (5306, 5311, 5312, 5404, 5406) selected as potential highly functional based on content. (5405, 5406, 5311) relatively higher hydrolysates than other...

Carrot (Daucus carota), one of the most economically important root vegetables, shows a wide range morphological and biochemical diversity. However, there is lack simultaneous systematic study regarding composition characteristics in carrot genetic resources, which crucial for crop improvement. For this reason, characteristics, carotenoids, free sugar content 180 resources grown open field conditions from March to June 2020 were accessed select lines potential breeding program. Altogether,...

This study monitored changes in major carotenoids (lutein, ⍺-carotene, and β-carotene), free sugars (fructose, glucose, sucrose), ascorbic acid, vitamin E, phytosterols (campesterol, stigmasterol, β-sitosterol), fatty acid composition, total phenol content (TPC), flavonoid (TFC), anthocyanin content, antioxidant activities (AA); ferric-reducing power (FRAP) 2,2′-azino-bis (3-ethylbenzothiazoline-6sulfonic acid) [ABTS] assays, the inner outer root tissues of nine carrot genotypes with orange,...

This study was performed to monitor glucosinolate (GSL) profile, total phenol, ascorbic acid, flavonoid contents, and antioxidant activity in florets of six broccoli (Brassica oleracea L. var. italica Plenck) genotypes at three different inflorescence developmental stages. The level phytochemicals activities varied significantly among Out the eight GSLs identified this study, only five were present all their respective Glucoraphanin (GRA), a major GSL, increased towards later stages...

This study aimed to determine the optimal light conditions for protected cultivation of Centella asiatica—a herbaceous medicinal plant with high bioactive content and antioxidant potential. The growth, triterpene glycoside content, total phenol (TPC), flavonoid (TFC), activities seedlings grown five weeks under different intensities (150 200 μmol m−2 s−1) qualities (red blue ratios: 10:0, 8:2, 6:4) were evaluated. Light intensity quality significantly affected studied parameters. At 150 s−1...

Pulmonary aspergillosis may be classified under three categories, depending upon whether the host is atopic or immunocompromised: invasive aspergillosis, allergic bronchopulmonary (ABPA) aspergilloma. However, it not always possible to effectively categorize this disease. We experienced a case of endobronchial aspergilloma, which was difficult categorize, in healthy male patient. The chest X-ray and computed tomography showed an ill-defined nodule mimicking lung cancer. Fiberoptic...

To assess South Korean commercial tomato cultivars, regular and cherry cultivars were grown in the greenhouse evaluated for color attributes, titratable acidity, pH, total soluble solids, carotenoids (lycopene β-carotene), phenols, flavonoids, vitamin C, antioxidant activity.
