Variety traits

Plant height — broccoli

Brassica oleracea L. (Broccoli Group)

The height of broccoli is a key morphological trait that influences lodging resistance, planting density selection, and adaptation to growing conditions. For the majority of varieties and hybrids, the height range is from 50 to 100 cm.

In the reference 27 varieties crop Broccoli, where this is mentioned in the description.

When assessing the crop, plant height is measured with a ruler or measuring rod in centimeters from the root collar to the growing point, represented by the top of the inflorescence or the point of attachment of the upper leaves. Typical height values vary within the range of 50–100 cm, with specific figures determined by the genetic characteristics of varietal types, such as Calabrese or sprouting broccoli.

This parameter is critical for agronomic practices, as tall forms are susceptible to lodging during strong winds or under the weight of the harvest, which necessitates hilling. Plant height, in combination with rosette size, dictates the planting scheme to avoid shading and ensure the proper formation of a marketable head.

Plant height values can change under the influence of external factors: at high temperatures, broccoli tends to divert resources into excessive vegetative growth at the expense of inflorescence development. In agronomic practice, height is usually evaluated in comparison with control samples during variety trials, as uniform standardized categories of dwarfism or tallness for this crop have not been established.
