Figure 3From: Abscisic acid induced freezing tolerance in chilling-sensitive suspension cultures and seedlings of riceTime course dependent changes in freezing tolerance (LT 50 ) of rice suspension cells incubated with or without 75 μM ABA at 25°C (1 g cell inoculum in 50 mL of medium). Freezing tolerance (LT50) was determined by plotting the survival at each subfreezing temperature determined by TTC reduction assay.Back to article page
