“…2008). The high level of correlation between the resistance against cold‐induced photoinhibition and the values of t EL50 in the laboratory experiment indicates that chlorophyll fluorescence‐based measurements may be a simpler and faster alternative to electrolyte leakage studies (Jenkins and Roffey 1974).…”

Freezing tolerance of 60 breeding lines of winter hexaploid triticale (×Triticosecale Wittmack) was studied in the field‐laboratory experiment. The experiment was repeated over three winters. The survey was also carried out in plants grown and cold‐acclimated in the laboratory. In both the experiments, plant survival analysis and chlorophyll fluorescence‐based studies on energy flows in photosystem II (PSII) (JIP‐test) after freezing of detached leaves were performed. In the laboratory experiment, the temperature of 50 % electrolyte leakage from leaves and the resistance against cold‐induced photoinhibition were additionally investigated. In the case of plants’ cold‐acclimated in the field, determination of the freezing tolerance of PSII gave similar results as the determination of freezing tolerance of whole plants. Both traits were strongly affected by genotype–environmental interactions, but these effects were less visible for PSII characteristics. In the laboratory experiments, a strong correlation between freezing tolerance and the tolerance for cold‐induced photoinhibition of photosynthesis was observed. The possibility of the use of chlorophyll fluorescence‐based techniques for the determination of freezing tolerance in triticale is discussed.

“…Metabolic changes associated with reproductive development at that time may affect hardiness by increasing potential growth rates (Parsons & Robson, 1980), a factor which is often not considered when freezing seedlings . (Jenkins & Roffey, 1974 ;Fuller & Eagles, 1978) was used to test tiller material . It consisted of an insulated steel bath (1 .6m x 0.86 m x 0 .31 m) containing 455 litres of 50% (v/v) ethylene glycol and water .…”

Assessments of freezing tolerance, estimated in terms of temperature at which 50% mortality occurs (= LT 50 ), 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 .

Field and laboratory experiments were carried out to determine the effect of cold stress on fifteen wheat (Triticum aestivum L.) cultivars. Fifteen cultivars including winter cultivars viz., Sayson, Marton, Gaskoghen, C-82-12, C-82-13, facultative cultivars: Alvand, Mahdavi, Zarrin, Marvdasht, Tous and spring cultivars viz., Shiraz, Pishtaz, M-79-7, M-81-13, Kavir were sown at three dates (15 October, 15 November and 15 December) based on complete blocks design with three replications under field conditions. In laboratory experiment the same cultivars were evaluated under cold stress at two and four leaves growth stages. Results showed that there were significant differences among cultivars in grain yield, potassium accumulation, lethal temperature (LT 50 ), ion leakage, chlorophyll content a and b among growing stages, genotypes and interaction between them. Ion leakage was the highest for M-81-13 cultivar (81.12ds m -1 ). C-82-12 and Gaskogen with more than 6.44 % and Sayson with 4.89 % potassium accumulations had the highest and lowest values. Lethal temperature of Gaskogen and Shiraz were -42 and -28°C. Gaskogen was tolerant to cold stress and hadn't high grain yield potential. The highest chlorophyll a and proline content were obtained for Marvdasht and Gaskoghen with 2.51mg.g-1 and 0.34g.g-1 at two leaves growth stage. In contrast the lowest chlorophyll b related to Sayson and C-82-12 with 1.37 and 1.39 mg g-1 , respectively. All cultivars at first planting date had more grain yield than two other planting dates.
