However, dormancy can be broken by holding the tubers at 20-30°C for 30-45 days (which are common ambient conditions in the tropics, ie dormancy is broken quickly in such climates), or by treating them with chemicals such as chlorhydrin, potassium or sodium thiocyanate, or gibberellic acid.
The tubers of D. alata have a definite period of dormancy of 2-4 months, which may be broken by treatment with ethylene chlorhydrin.
Most yams have a definite period of dormancy, but this may be broken by the use of a chemical such as ethylene chlorhydrin, where production of out-of-season tubers is required.
In a similar way, the number of the units for chlorhydrin, the next step, was increased from three to eighteen.
