“…The characteristic flavor of onions and garlic is attributed to the sulfur-containing volatiles. The formation of these volatiles is due to enzymatic reactions catalyzed by alliinase, and is accompanied by pyruvic acid production [65][66][67][68]. Variations in the enzymatic pyruvic acid (PA) content of garlic are illustrated in Table 2.…”

The main aim of this study was to evaluate the yield and compliance of selected Iranian garlic (Allium sativum L.) cultivars, including Tuyserkan (TSN), Heydareh (HDH), Mouien (MUN), and Taroom (TRM), during two growing seasons. The TRM cultivar germination rate is higher than the other cultivars studied. The TRM cultivars have quite remarkable values for the dry weight, fresh weight, stem diameter, and the number of leaves present. The fresh weight and dry weight of the TRM cultivar for the second year are 33.8 t/ha and 16.7 t/ha, respectively. However, on average, the HDH cultivar is the tallest plant in the experiments. Average pyruvic acid content in fresh samples of the TRM and HDH cultivars is 78 µm/gfw and 69.3 µm/gfw, respectively. It is observed that there are remarkable differences in the level of pyruvic acid between the different cultivars. The growth, development, and yield of plants are highly dependent on their genetic characteristics; in this experiment, the TRM cultivar shows a good yield (16.7 t/ha), and the evaluated characteristics improve compared to the other cultivars studied, which could be due to the high compatibility of this cultivar to the environmental conditions of the study. The excellent performance on the yield of TRM makes this cultivar more appreciable on a commercial level.

“…The onion is an important source of nutritional components, such as proteins, carbohydrates, sugars (arabinose, fructose, galactose, glucose), vitamins, lipids, minerals, and some flavonoids and polyphenols components [92]. Onions are a rich source of vitamin A (β-carotenoid), vitamin B (B1, B2, B3), vitamin E (α-tocopherols), and vitamin C (ascorbic acid) [93,94], which exhibit antioxidant activities. They are also a good source of diverse dietary flavonoids, phospholipids, and glycolipids, along with organosulfur compounds, such as allicin, alliin, diallyl disulfide, S-methyl-L-cysteine S-oxide, propanethial S-oxide, and 3-mercapto-2methypentan-1-ol [95].…”

Antioxidant and Antimicrobial Properties of Selected Phytogenics for Sustainable Poultry Production

et al. 2022

The use of antibiotic growth promoters (AGP) in poultry production not only promotes the emergence of pathogenic multi-drug resistant bacteria, but it also compromises product quality, threatens animal and human health, and pollutes the environment. However, the complete withdrawal of AGP without alternatives could result in uncontrollable disease outbreaks that would jeopardize large-scale poultry intensification. Thus, the use of phytogenic products as potential alternatives to in-feed AGP has attracted worldwide research interest. These phytogenic products contain numerous biologically active substances with antioxidant and antimicrobial activities that can enhance poultry health, growth performance, and meat quality characteristics. In addition, the incorporation of phytogenic products as feed additives in poultry diets could result in the production of high-quality, drug-free, and organic poultry products that are safe for human consumption. Thus, this review examines the current evidence on the antioxidant and antimicrobial properties of a selection of phytogenic products, their effects on nutrient utilization, and physiological and meat quality parameters in poultry. The paper also reviews the factors that could limit the utilization of phytogenic products in poultry nutrition and proposes solutions that can deliver efficient and sustainable poultry production systems for global food and nutrition security.

“…An estimated 4.3million hectares of land are used to produce 724.25million tons of onions worldwide (Pareek et al 2017). Onion production has increased in line with the country's population growth (Mahmood et al 2021;Qazi et al 2021). The top countries in the world for onion production are China, India, the US, Egypt, Iran, Turkey, and Pakistan.…”

The onion (Allium cepa L.) is a biennial vegetable with regard to seed production. Seed yield is influenced by high temperature at the time of anthesis and seed setting in Punjab. Thiourea (TU) and PGPRS have been used in different crops to induce stress tolerance and to increase the yield. Two experiments were conducted to study the effect of different concentrations of thiourea (0, 5, 10, 15 and 20mM) and different PGPRS (Control, PsJN and FD17) on onion seed production. Thiourea and PGPRS were applied as foliar spray at post-anthesis stage in onion seed crop. Three replications were used under RCBD. In first experiment, maximum values of scape height was 30.367cm in 15mM TU, number of scapes (10.33), thousand seed weight (4.20mg), umbel diameter (5.29mm), weight of seed per umbel (0.34g), seed yield per plant (3.21g), plumule length (7.70cm), radicle length (4.17cm), germination percentage (85.66%), yield of seed per plot (369.85g/ft-2), dry weight (70.70mg) and fresh weight (431.64mg) of seedling in 5mM TU and seed germination duration as 16 days in 15mM of TU. Most of the results were higher in 5mM application of TU. While in second experiment, scape height (29.8cm), umbel diameter (5.29mm) and number of scapes per plant (10.3) were not significantly affected by different treatments yet FD17 showed the best results. Seed yield per plant (3.31g/plant) and yield of seed per plot (296.5g/ft2) were significantly (P<0.00) affected by FD17 treatment. Almost all the results of FD17 were superior to PsJN. In conclusion of this research, overall, the performance of thiourea (especially 5mM) was better as compared to others.
