Abstract The germination and flowering responses to cold treatment were investigated in 32 ecotypes of Arabidopsis thaliana. A month-long cold treatment at the seed stage decreased the time until flowering in all but one strain, whereas a 3-d cold treatment had little, or the opposing effect. A month-long cold treatment at the rosette stage also decreased the time until flowering, but was less effective than seed cold treatment. Seed and rosette cold treatments did not have an additive effect on time until flowering. Cold treatment usually increased the speed of germination, however no clear response patterns for the probability of germination were detected. These findings are discussed in relation to the life cycle of the plant.
