Summary
Assessments of freezing tolerance, estimated in terms of temperature at which 50% mortality occurs (=LT50), were obtained for 86 Lolium perenne accessions using a glycol bath test on naturally hardened field plants. Significant correlations were obtained between LT50 and both heading dates of accessions and minimum temperature of the coldest month near their sites of origin. The effects of temperature and reproductive development on the hardening/dehardening of plants and their growth after freezing are discussed.
