Variety traits
Bromus catharticus Vahl
The plant height of Bromus catharticus is measured at the heading stage from the stem base to the tip of the panicle and ranges from 60 to 160 cm. This trait is closely correlated with biomass yield and reflects the productivity of the forage crop.
In the reference 3 varieties crop Rescue grass, where this is mentioned in the description.
According to international testing protocols, the height of Bromus catharticus is recorded at the heading or flowering stage. The measurement is taken as the distance from the soil surface to the highest point of the plant, represented by the tip of the inflorescence, with the stems held in a vertical position without stretching.
The plant height range of the species varies significantly depending on the genotype and the age of the stand. Studies of natural populations show values from 95 to 160 cm, while the average height of the crop can increase from 76.1 cm in the year of sowing to 111.4 cm in the second year of growth.
Height is an important selection trait that determines forage productivity. There is a direct correlation between this indicator and dry biomass yield, however, excessive growth increases the risk of lodging, which is taken into account when choosing harvesting methods and assessing the crop's ability for rapid regrowth.
