Despite its enormous cost, the helmet had little meaning in an Ottoman context, as sultans did not traditionally wear crowns. [11] It is likely that the four crowns topping the helmet were melted down for reuse at a later date, while the helmet itself, which formed the lowest level of the piece, was possibly presented as a gift to Ferdinand I, Holy Roman Emperor [12] as a similar crown appears in contemporary woodcuts. Onion bulbs are produced by sowing seeds in a dense pattern in early summer, then harvested in the autumn when the bulbs are still small, followed by drying and storage. These bulbs planted the following spring grow into mature bulbs later in the growing season. [60] Certain cultivars used for growing and storing bulbs may not have such good storage characteristics as those grown directly from seed. [14]

Spring onions or salad onions may be grown from the Welsh onion ( A. fistulosum), as well as from A. cepa. Young plants of A. fistulosum and A. cepa look very similar, but may be distinguished by their leaves, which are circular in cross-section in A. fistulosum rather than flattened on one side.

After the 16th century, the helmet was long known only from the closely similar prints by Agostino Veneziano and others (it is not entirely clear which of these first created the image). These appear to combine the features of Süleyman lifted from other portraits available in Venice, while the helmet itself was recorded when it was exhibited in Venice, before it reached the sultan. The helmet was widely thought to be a fanciful invention of the printmakers, until 20th-century scholars rediscovered the records of the real object.

This genus also contains several other species variously referred to as onions and cultivated for food, such as the Japanese bunching onion Allium fistulosum, the tree onion Allium× proliferum, and the Canada onion Allium canadense. The name wild onion is applied to a number of Allium species, but A. cepa is exclusively known from cultivation. Its ancestral wild original form is not known, although escapes from cultivation have become established in some regions. [5] The onion is most frequently a biennial or a perennial plant, but is usually treated as an annual and harvested in its first growing season.

In 2021, world production of onions and shallots (as green produce) was 4.6 million tonnes, led by China with 19% of the world total, with Mali, Japan, and South Korea as secondary producers. [67] Storage In the home Yellow or brown onions are sweet, with many cultivars bred specifically to accentuate this sweetness, such as Vidalia, Walla Walla, Cévennes, and Bermuda. [22] Yellow onions turn a rich, dark brown when caramelised and are used to add a sweet flavour to various dishes, such as French onion soup. Education The large size of onion cells makes them useful for microscopy. These cells from the epidermis of a red onion are naturally pigmented.

An onion ( Allium cepa L., from Latin cepa meaning "onion"), also known as the bulb onion or common onion, is a vegetable that is the most widely cultivated species of the genus Allium. The shallot is a botanical variety of the onion which was classified as a separate species until 2011. [2] [3] :21 Its close relatives include garlic, scallion, leek, and chive.

The triploid onion is a hybrid species with three sets of chromosomes, two sets from A. cepa and the third set from an unknown parent. [3] :19 Various clones of the triploid onion are grown locally in different regions, such as 'Ljutika' in Croatia, and 'Pran', 'Poonch', and 'Srinagar' in the India-Kashmir region. 'Pran' is grown extensively in the northern Indian provinces of Jammu and Kashmir. There are very small genetic differences between 'Pran' and the Croatian clone 'Ljutika', implying a monophyletic origin for this species. [73]
