Summary

THE HARDENING ABILITY OF DIFFERENT VARIETIES OF PHALARIS ARUNDIACEA L. UNDER DIFFERENT HARDENING CONDITIONS IN CONTROLLED CLIMATE WAS TESTED BY FREEZING OR INOCULATION WITH FUSARIUM NIVALE (FR.) CES. CHANGES IN CARBOHYDRATE STORES DURING HARDENING AND SUBSEQUENT DARK STORAGE WERE INVESTIGATED. THE GREATEST RESISTANCE TO FREEZING WAS ACQUIRED AT ABOUT 274 K (1 DEG C). EFFECTS OF PHOTOPERIOD DURING HARDENING WERE OBSCURED THROUGH POSSIBLE SIDE EFFECTS OF THE TECHNICAL EQUIPMENT USED. NORWEGIAN VARIETIES SURVIVED THE FREEZING TEST BETTER THAN AMERICAN/CANADIAN VARIETIES. THE FREEZING AND THE FUNGAL ATTACK DID NOT SCREEN THE VARIETIES IN THE SAME ORDER. THE RESULTS ARE DISCUSSED ON THE BASIS OF PREHARDENING CONDITIONS AND PHYSIOLOGICAL AND MORPHOLOGICAL RELATIONSHIPS.
