White clover populations in pastures at northern mid-latitudes have been naturally maintained for many decades through seedling recruitment in spring and vegetative propagation throughout summer and fall. In addition, graziers periodically broadcast seed of commercial white clover cultivars in their pastures to ensure production of high quality large leafed plants. However, in actively grazed managed permanent pastures, white clover plant establishment is primarily by root-shoot production at stolon internodes.
Many other factors also influence white clover population structure and dynamics (Grime et al., 1988). This plant species is intolerant of drought, severe ...
