| Popis: | In order to determine freezing tolerance of 14 wheat cultivars including Anza, Bezostaja, Pishtaz, Tous, Zagros, Zarrin, Shahryar, Falat, Qods, Glenson, Maron, Navid, Niknejad and MV-17 that were grown on field, samples of each cultivar after hardening in the field were harvested in 4-6 leave stages and trimmed to 2cm above and below the crowns and put on the thermogradient freezer. After freezing in the range of 0 to -20 oC, samples were transferred to the greenhouse and planted in the pots. Survival percentage, height, leaf area, chlorophyll content, dry weight, LT50 and DMT50 were determined after 3 weeks. Survival percentage after freezing was different in cultivars (P |
