Leafiness — Italian ryegrass

Lolium multiflorum Lam. ssp. italicum (A. Br.) Volkart

A qualitative characteristic of a variety that determines the ratio of leaf mass to stem mass in the crop structure. Leafiness directly affects the nutritional value of forage, as leaves contain more protein and are more digestible compared to stems.

In the reference 9 varieties crop Italian ryegrass, where this is mentioned in the description.

In the breeding practice and variety testing of Italian ryegrass, leafiness is assessed by experts on a 9- or 12-point scale, where higher scores correspond to better indicators. This trait does not have a specific standardized measurement methodology in unique physical units.

Nitrogen nutrition and moisture regime have a significant influence on the formation of leaf mass in ryegrass. In addition, the indicator depends on the ploidy of the variety: tetraploid forms often have broader leaves compared to diploid ones, which is reflected in the visual assessment of leafiness.
