Abstract

Abstract Cold hardiness of Hedera helix L. var. Thorndale was ultimately unaffected by photoperiod. Anthocyanin accumulation was a photoperiodic-high light intensity response. There was no correlation between anthocyanin content and cold hardiness in plants exposed to different photoperiods and light intensities.
