Plant height — opium poppy

Papaver somniferum L.

The height of the opium poppy (Papaver somniferum) is a key morphological trait in variety testing, ranging from 60 to 150 cm depending on the variety and growing conditions.

In the reference 31 varieties crop Opium poppy, where this is mentioned in the description.

For opium poppy, stem height serves as an important criterion for grouping varieties during state trials, allowing for the classification of short-, medium-, and tall-stemmed forms. Standardization of this trait is necessary to create uniform growth conditions, prevent mutual shading of plants in plots, and ensure the representativeness of the obtained data.

This parameter is closely linked to the crop's lodging resistance, which decreases in tall forms under the influence of weather conditions. Optimal height parameters are critical for mechanized harvesting, as excessively tall plants impede the operation of harvesting machinery during the collection of capsules and seeds, and are also influenced by sowing density, light exposure, and water availability.
