“…% were obtained by planting in wide furrows and the reverse was true for planting in ridges during the both growing seasons. The decrease in T.S.S due to delaying transplanting date from 15ᵗʰ December to 1ˢᵗ January agreed with (Coolong & Randle, 2003), who found out that the soluble solid content of mature bulbs had a negative linear response to increasing temperature.These results are in general agreement with those obtained by Kandil et al (2013), Kanwar & Akbar (2013) and Bharti & Ram (2014). The superiority of low density in bulb diameter may be attributed to decreased competition for nutrients and moisture at low dense plants that resulted in bulbs with larger diameter and higher bulb weight.…”

“…Besides, Bloem et al reported a distinctive accumulation pattern of alliin that decreased from 3.0 to 1.1 mg/g of fresh weight (fw) during the vegetation period in garlic grown in a greenhouse. Therefore, except for sowing time, other factors, such as environmental conditions, , may also affect the accumulation pattern of metabolites in a garlic bulb.…”

“…Besides, Bloem et al 28 reported a distinctive accumulation pattern of alliin that decreased from 3.0 to 1.1 mg/g of fresh weight (fw) during the vegetation period in garlic grown in a greenhouse. Therefore, except for sowing time, other factors, such as environmental conditions, 29,30 may also affect the accumulation pattern of metabolites in a garlic bulb. Allicin is the enzymatic hydrolysate of alliin in the presence of alliinase (EC 4.1.4.4), 31 which represents about 70% of the overall thiosulfinates and is considered to be the principal bioactive compound found in fresh garlic.…”

Garlic-specialized metabolites contribute to both spicy flavor and healthy function of garlic. Their accumulation pattern and regulatory mechanism vary greatly at different environments and maturities. Herein, metabolomics models were built to evaluate and predict the quality and chemical composition variances of four garlic varieties in two regions at six growth stages. A total of 91 metabolites were identified, and their accumulation pattern during growth in three varieties of garlic in Shandong was similar but obviously distinct from that planted in Heilongjiang. Active metabolism for organosulfur compounds and amino acids was observed, and most metabolites with the “γ-glutamyl-” group were the storage compounds of nitrogen and sulfur in garlic because they increased remarkably during growth. The levels of functional components in garlic varied among different stages, and reliable prediction models for these compounds were provided, which may give a new idea for the estimation of garlic quality and confirmation of the best harvest time.

“…Planting time also affects the mean weight and grade of bulbs as well as marketable yield: the values of these parameters gradually decrease when the planting is delayed from mid-winter to late-winter, as a consequence of crop length reduction which shortens the time available for synthesis and storage of metabolites into the bulbs (Boyhan et al 2009a;Caruso et al 2014). In addition, the increase of growth temperature from 27°C to 32°C results in the reduction of bulb size (Coolong, Randle 2003b) and up to 34°C enhances ripening (Coolong, Randle 2006). Moreover, the dry weight of ripe bulbs may show linear and adverse correlation with temperature (Steer 1982) or just the opposite trend (Coolong, Randle 2003b).…”

Sekara A., Pokluda R., Del Vacchio L., Somma S., Caruso G. (2017) The aim of this review is a wide description of the relationships between growing conditions and bulb yield and quality of onion (Allium cepa L.), focused particularly on long-day cultivars suitable for storage. Marketable yield decreases according to the reduction of crop length caused by the increase of growth temperature. The nutritive requirements of storage onion are highest during the vegetative growth. The application of humic substances and the inoculation of mycorrhizae may enhance bulb growth and quality, mainly under stress conditions. Onion is a slow-growth, shallowrooted crop with non-shading habitus and therefore its productivity is highly dependent on water availability in the soil, proper fertilization and weed control. The shelf-life of onion bulbs is a genetic trait, improvable by efficient crop and post-harvest management, and adequate conditions of bulb storage. The quality of storage onion bulbs is ascribed to several indicators, such as thiosulfonates, pyruvic acid, soluble solids, sugars, and many other biological compounds. This review is also focused on onion quality as affected by the interactions among genotype, environment, farming practices and post-harvest management.
