Answer:
- Usually, onions grow underground, they are frequently mistaken for roots. Others believe they’re stems because the plant’s upper section is mostly leafy
- An onion isn’t a root or a stem in the traditional sense. It’s a tunicated bulb, or altered stem, with fleshy leaves that keep food and transmit it to other sections of the plant as needed
- The onions are a member of the Allium genus, so they are among the most widely farmed plants inside the genus
- Onion farming stretches back around 7000 years. However, it is unknown when or where it originated
- Onions are distinguished by empty leaves as well as a flattened base in which both root & fleshy leaves sprout. They are also based on the common onions or bulb onions
- An onion’s stem, yet unlike the ginger, is devoid of nodes and internodes
- When processing onions, the flattened bottom is the hard portion just at the bottom of the onion that one cuts off and discards
- A stem might be considered on this basis. On just this stalk, leaves appear piece by piece, one after the other, forming a concentric round around with a bud in the centre
- Whether you chop the onion horizontal or vertical, this cluster of leaves is evident
Bulbing
- This is how the onion bulbs we collect grow and mature. It happens when the leaves that grew from the base point begin to enlarge as they collect nourishment
- Day-length, commonly referred to as the photo-period, is among the elements that affect how large plant bulbs develop, according to Dr. Brunel. This means that the bigger the bulb develops, the longer a day is at the right temperatures
- In this regard, several sorts of onion cultivars exist based on the quantity of light they require
