Potted plants, from ah open standing-out ground, taken into a growth room (65 degrees F. and 9-hour photoperiod) in early January all began making vigourous shoot growth within 14 days, whereas plants that had been taken in earlier grew very little.

During the breaking of dormancy starch was gradually transformed into soluble sugars.
