In the first experiment reported, maintenance of fully grown canes of the raspberry variety Malling Jewel for six weeks at 45F and with a 9 hr. daylength resulted in the initiation of flower buds without the onset of dormancy. In the second experiment, treatment of dormant canes of the same variety for 30 hrs. with ethylene chlorhydrin vapour resulted in loss of their dormancy. Both of these alternative treatments are considered to be superior to some known methods of producing out-of-season fruits for experimental purposes.
