Vigor of subterranean clover

Trifolium subterraneum L.

Seedling vigor in Trifolium subterraneum L. determines the rate of canopy closure, competitiveness in the sward, and the success of initial establishment.

In the reference 4 varieties crop Subterranean clover, where this is mentioned in the description.

For this crop, the trait is closely linked to seed size: larger seeds provide better performance due to greater nutrient reserves. High vigor allows the plant to suppress weeds faster and utilize environmental resources more efficiently, which is critically important when overseeding or on poor soils.

In scientific practice, vigor is assessed visually on a 1-10 scale, where scores of 6 and above are considered high, or quantitatively by measuring seedling dry matter at 21 days, rate of emergence, pace of trifoliate leaf development, and hypocotyl length. The trait is relative and is always compared within the framework of a specific cultivar trial.
