This study suggests that application of controlled stress to the cauliflower transplants through lowering temperature improves plant tolerance to field conditions, and, to some extent, unlocks yield potential of the crop. This is an important observation because most of works on cauliflower focused on the plant response to environmental conditions when they were already in the field (Pearson et al., 1994; Wurr and Fellows, 1998, 2000). We showed that low, non-freezing temperature applied to the transplants may affect subsequent yield of cauliflower. We can conclude that plants may activate acclimation mechanisms through lowering the temperature at this stage, helping them in field environment.
