Among several environmental factors (light, moisture, temperature) that can affect bulb development, temperature has been established as playing a predominant role in controlling growth and flowering in bulbs [1]. For most of them, a “warm-cold-warm” sequence is required to complete their lifecycle. Different genera and species demand various temperature optima, but, in general, the optimal temperature for the initial organogenesis ranges from 15 to 21 °С, while low positive temperature is required for the development of a flower stalk and well-formed flowers (Table 1) [1]. This period of autumn-winter cooling seems to be extremely important for flower development, as its absence leads to slow shoot growth and severe flowering disorders [4–13].
