Chilling stress during germination often causes severe injury. In the present study, maize seed germination and shoot growth under chilling stress were negatively correlated with the dose of tebuconazole in an exponential manner as predicted by the model Y = A + B × e (−x/k) . Microencapsulation was an effective means of eliminating potential phytotoxic risk. The gibberellins (GAs) contents were higher after microencapsulation treatment than after conventional treatment when the dose of tebuconazole was higher than 0.12 g AI (active ingredient) kg −1  seed. Further analysis indicated that microencapsulation can stimulate ent-kaurene oxidase (KO) activity to some extent, whereas GA 3-oxidase (GA3ox) and GA 2-oxidase (GA2ox) activities remained similar to those in the control. Genes encoding GA metabolic enzymes exhibited different expression patterns. Transcript levels of  ZmKO1  increased in the microcapsule treatments compared to the control. Even when incorporated into microcapsules, tebuconazole led to the upregulation of  ZmGA3ox1  at doses of less than 0.12 g AI kg −1  seed and to the upregulation of  ZmGA3ox2  when the dose was higher than 0.12 g AI kg −1  seed. With increasing doses of microencapsulated tebuconazole, the transcript levels of  ZmGA2ox4 ,  ZmGA2ox5  and  ZmGA2ox6  exhibited upward trends, whereas the transcript levels of  ZmGA2ox7  exhibited a downward trend.
