Figure 7From: Abscisic acid induced freezing tolerance in chilling-sensitive suspension cultures and seedlings of riceHeat tolerance of rice suspension cells incubated in the presence or absence of 75 μM ABA for 7 days at 25°C (1 g cell inoculum). Survival of cells directly exposed to 43°C for 0–180 min (without heat shock pretreatment) was determined by regrowth capacity compared to that of non-stressed cells.Back to article page
