The rice variety Tesanai 2 is susceptible to tochilling. Expose of the seedlings grown at 28 ± 1 ° C and under a photo flux density (PFD) of 30 μmol / m ~ 2 s to 1 ° C and under a PFD of 150 μmol / m ~ 2 s for 2 d caused a physiological disor-der called chilling injury which reduced the sur-vival rate to 50%. the experimental results in-
