Vigor — Onion

Allium cepa L.

A complex indicator characterizing seed germination activity and the intensity of vegetative mass accumulation during the growing season.

In the reference 29 varieties crop Onion, where this is mentioned in the description.

The seed vigor of onion determines its ability for uniform germination and seedling development under adverse conditions. A high value for this trait is critical for achieving uniform emergence and high-quality crop stand, while low values lead to thinning of crops and reduced productivity.

Regarding the growing plant, vigor represents an integral assessment of development dynamics, including height increase, biomass accumulation, and leaf apparatus formation. This trait influences the onion's stress tolerance, its ability to compete with weeds, and resource-use efficiency depending on varietal characteristics, such as those of the Rijnsburger group.
