freezing tolerance still exists in most grasses and can be effectively used in breeding ( Larsen, 1994 ). A previous freezing study with six saltgrass clones ( Shahha et al., 2003a ) indicated variation in freezing tolerance and suggested that freezing

In temperate climates, asparagus phenology includes the induction of fern senescence and crown dormancy in the fall, quiescence in the winter, and regrowth in the spring. For optimal survival, plants must acquire adequate freezing tolerance, which
