Variety traits

Spinach plant height

Spinacia oleracea L.

Spinach height is defined as the distance from the base of the rosette to the tip of the leaves or the flowering stem. This metric is critical for assessing the degree of rosette development, produce market quality, and determining the timing of bolting.

In the reference 42 varieties crop Spinach, where this is mentioned in the description.

The trait is measured in centimeters and typically ranges from 15 to 50 cm throughout the growing season. Varieties intended for harvesting at the 'baby' or 'teen' leaf stage are characterized by values up to 20–25 cm, while mature plants prior to flowering can reach 50–60 cm.

Plant height is closely linked to its habit, including petiole length and leaf orientation. Excessive height, particularly under long-day conditions, serves as an indicator of the transition to the bolting phase, which leads to tissue coarsening, the accumulation of bitterness, and a significant reduction in marketable yield.

Breeding programs focus on developing varieties with an optimal rosette habit to facilitate mechanical harvesting. This involves balancing biomass with resistance to premature bolting, as rapid flower stalk growth negatively affects the quality of the leaf product.
