White clover (Trifolium repens L.) persists in pastures mainly by stolon growth. Morphologically complex (i.e., highly branched stolons) plants of white clover generally persist longer. We hypothesized that biotic and abiotic stresses limit white clover production on grazing lands by fragmenting plants into smaller, less competitive individuals. We measured changes in the size and structure of plants in a white clover-orchardgrass (Dactylis glomerata L.) sward during a drought (1999) and a ...

Growth and complexity of white clover stolons in response to biotic and abiotic stress.(Forage & Grazing Lands)
Crop Science ; WHITE CLOVER is a critical component of pastures in temperate humid grazing lands and persists via clonal growth of stolons and seedling recruitment (Pederson, 1995). Through N fixation, it supplies much of the N needed for growth of itself and other species within the sward. Persistence of white
Genetic variation of RAPD markers for North American white clover collections and cultivars. (Crop Breeding, Genetics & Cytology).(Statistical Data Included)
Crop Science ; NATURALIZED WHITE CLOVER, originally brought to North America by European colonists, is a widely adapted and productive forage legume species in eastern North America (Gibson and Cope, 1985; Fraser, 1989). Currently, most recommended varieties originate from European cultivars (Gibson and Cope,
White clover response to a water-application gradient.
Crop Science ; PERIODS of limited soil water are a common occurrence during the summer in the southeastern USA. These periods can be particularly detrimental to white clover, which is less tolerant of drought than other perennial, temperate forage legumes due to its shallow root system and inability to
Plant density and environment effects on orchardgrass--white clover mixtures. (Forage & Grazing Lands).
Crop Science ; COOL-SEASON GRASS PASTURES predominate in grazing lands of the northeastern USA (Baylor and Vough, 1985). White clover is a critical component of mixed species pastures in this region. Through N fixation, it supplies much of the N needed for growth of itself and other species within the sward.
Genetic Variation within and among White Clover Populations from Managed Permanent Pastures of the Northeastern USA.
Crop Science ; 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
Evidence on the Molecular Basis of the Ac/ac Adaptive Cyanogenesis Polymorphism in White Clover (Trifolium repens L.)
Genetics ; ABSTRACT White clover is polymorphic for cyanogenesis, with both cyanogenic and acyanogenic plants occurring in nature. This chemical defense polymorphism is one of the longest-studied and best-documented examples of an adaptive polymorphism in plants. It is controlled by two independently
Molecular Analysis of White Clover Population Structure in Grazed Swards during Two Growing Seasons.
Crop Science ; WHITE CLOVER is an important functional component of temperate grazed ecosystems because of symbiotic nitrogen fixation and its high nutritional quality (Caradus et al., 1996) as an animal feed. White clover is a stoloniferous, obligately outcrossing, tetraploid species. It flowers prolifically
Growth of White Clover Ecotypes, Cultivars, and Germplasms in the Southeastern USA.
Crop Science ; WHITE CLOVER is a vital component of permanent pasture systems in New Zealand and Great Britain, contributing to greater animal performance and reduced reliance on N fertilizer. In both these countries, pastures are dominated by plants with highly branched stolons and small- to medium-leaf size

White clover clone response to alternative defoliation methods.
Crop Science ; Differences in growth of white clover subjected to grazing compared with clipping have been attributed to frequency of defoliation (Swift et al., 1992) and selective grazing by livestock (Evans and Williams, 1987). Swift and coworkers (1992) suggested that because differences in persistence among
