Summary

FLORETS OF 8 PROVENANCES REPRESENTING 3 NATIVE NORTH AMERICAN AZALEA SPECIES: RHODODENDRON CALENDULACEUM (MICHX) TORR, R. PRINOPHYLLUM (SMALL) MILLAIS, AND R. VISCOSUM (L) TORR, BEING GROWN IN BURLINGTON, VT, WERE COMPARED DURING 3 SEASONS FOR COLD HARDINESS BY LABORATORY FREEZING DURING COLD ACCLIMATION. THERE WAS ALARGE VARIABILITY IN THE NUMBER OF FLORETS KILLED WITHIN AN INFLORESCENCE IN RESPONSE TO FREEZING TEMPERATURES. COLD HARDINESS FROM MOST TO LEAST HARDY, WERE R. VISCOSUM, R. PRINOPHYLLUM AND R. CALENDULACEUM . IT SHOWED A SIGNIFICANTLINEAR RELATIONSHIP WITH THE DAILY MEAN TEMPERATURE OF THE 3 DAYS PRECEDING FREEZING TESTS.
