Variety traits

Plant height — onion

Allium cepa L. var. cepa

This trait characterizes the development of the plant's vegetative mass or reproductive organs. It is measured as the distance from the soil surface to the tip of the leaf or the point of inflorescence attachment.

In the reference 41 varieties crop Onion, where this is mentioned in the description.

During the vegetative phase, height is measured as the distance from the soil surface to the tip of the longest leaves. In the reproductive phase, the height of the scape is recorded — the distance from the soil level to the point of inflorescence attachment. A typical plant, including the flower stalk, can reach 90 cm.

This indicator varies significantly depending on genotype, nutritional conditions, plant density, and cultivation technology. The vigor of the foliage directly correlates with the intensity of photosynthesis, which determines bulb weight; however, excessive leaf elongation is considered a negative trait.

For mechanized harvesting, uniformity in plant height is prioritized over the absolute value. In seed production, flower stalk height is a key trait that influences the lodging resistance of seed crops.
