FIRE EFFECTS
SPECIES: Lolium perenne | Perennial Ryegrass 



IMMEDIATE FIRE EFFECT ON PLANT : 
Fire top-kills perennial ryegrass; high-severity fire can kill the
rhizomes [20,21].


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Fire stimulates the production of reproductive tillers in perennial
ryegrass [14].  When field burning was initiated on seed fields in
Oregon, seed yields tripled [21].


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY


FIRE MANAGEMENT CONSIDERATIONS : 
Fields of perennial ryegrass grown for seed are usually burned to
control blind-seed disease, remove crop residues, improve herbicide
effectiveness, and stimulate reproductive tiller initiation.  For
effective burning, it is important to ensure that crop residues are
fairly evenly distributed, since hot spots can be lethal to underground
rhizomes [14,20].
