Figure 2From: Abscisic acid induced freezing tolerance in chilling-sensitive suspension cultures and seedlings of riceFreeze survival of rice suspension cells cultured in the presence of ABA (0–75 μM) for 7 days at 25°C (1 g cell inoculum in 50 mL of medium). Freezing tests were done as described in the Methods and survival was determined by TTC (2,3,5-triphenyl tetrazolium chloride) reduction assays.Back to article page
