Variety traits
Trifolium subterraneum L.
In subterranean clover, the peduncle performs a geocarpic function, bending and elongating after pollination to bury the seed head into the soil.
In the reference 4 varieties crop Subterranean clover, where this is mentioned in the description.
After the self-pollination process, the peduncle begins to actively bend and elongate, directing the developing seed head toward the soil surface. This burial mechanism provides protection for the seeds and facilitates successful self-regeneration of the sward in pasture systems.
When evaluating a variety, the length of the peduncle is measured, which typically ranges from 20 to 80 mm, along with its relative proportion to the total length of the reproductive shoot. The ability of the peduncle to effectively bury seeds is a critical trait for population survival, with genotypic differences determining the depth of burial and the variety's adaptability to intensive grazing conditions or soil type.
