Allium cepa L. var. cepa
Onion vigor is a composite index reflecting seed germination activity, seedling emergence rate, and the intensity of initial leaf apparatus development. This parameter is comparative and is used to assess a variety's developmental potential during the early stages of vegetation.
In the reference 39 varieties crop Onion, where this is mentioned in the description.
High seed vigor in onions contributes to the establishment of stand density and uniformity of emergence, which increases the crop's resilience to unfavorable environmental conditions during early stages. While this indicator directly affects crop uniformity, its impact is most pronounced in the first weeks of the plant's life and does not always persist until the active bulb formation phase.
The trait is evaluated using laboratory methods, such as accelerated aging tests, germination rate analysis, and digital morphometry, as well as field biometric observations of plant height and dry matter accumulation during the first 50–60 days. Due to the lack of universal numerical standards, evaluation is conducted relative to a control sample or standard under specific soil and climatic conditions.
