Henke,

Dormancy isn't induced by temperature (although it has a small role). Dormancy is brought on by decreasing day length. A tree will not go dormant by only putting it in a colder place in the house.

Trees must be kept outside from late spring to late summer to induce dormancy, or have a way to experience the shorter and shorter daylengths that the summer to autumn transition bring.
