Variety traits

Plant height — onion

Allium cepa L.

This trait is not a standardized varietal indicator; when describing morphology, leaf length or scape height is recorded instead.

In the reference 35 varieties crop Onion, where this is mentioned in the description.

When describing onion morphology, it is standard practice to measure leaf length during the growing season or scape height in seed crops, rather than total plant height. The height of the scape in this crop can vary from 80–90 cm to 1.5 m.

The development of the leaf apparatus is of agronomic importance, as it determines the accumulation of photosynthates for bulb filling. Growth indicators are influenced by sowing density, water regime, and nutrient availability; however, excessive leaf growth can be an indirect indicator of planting density.
