Abstract

The present experiment was aimed to evaluate the fteezing tolerance of two cold tolerant (MCC426 and MCC252) and a cold susceptible (MCC505) CHICKPEA genotypes. The study was carried out in a split-plot factorial design with three replications. Factorial arrangement of genotype and ACCLIMATION (acc1imationand non ACCLIMATION) were imposed as main plot and temperatures (0, -4, -8, -12, 16, -20°C) as subplot. The effect of fteezing temperature (FT) on plant survival was significantly different among genotypes (p<0.05). According to the average effects of ACCLIMATION and FT, the plant survival in MCC426 and MCC252 was 40% and31% respectively more than in MCC505. Lethal temperature for 50% response (LT50) and temperature resulting in 50% lower dry matter (DMT50) in MCC426 were-10.8°C and -8.4°C, respectively and were lower than the other genotypes. ACCLIMATION increased the fieezing tolerance such that MCC426 tolerated up to -12°C without any mortality, however, at this temperature, plant mortality rates in MCC252 and MCC505 were 25.7% and 67.7%, respectively. Plant regrowth was affected by the intensity of FT, such that plant dry weight (PDW) and stem height (SH) in -12°C decreased about 63% and 50%, respectively, compared with non - ftozen control plants. The most fteezing damage was observed in MCC505, -12°C treatment caused 90%decreases in PDW and SH, but at this temperature, PDW and SH in MCC425 decreased 55% and 49% an<;lin MCC252, the reduction was about 60%and 54%, respectively. It seems that the use of controlled experiments would contribute to the evaluation offieezing tolerance and screening programs in CHICKPEA germplasm for the estimation of LT50 and DMT50.
