Abstract
In the previous paper, the writer described the results of the experiment for breaking the dormancy of gladiolus corms. The ethylene chlorhydrin treatment recommended by DENNY and other American investigators did not always prove to be necessary if the material was treated under suitable temperatures. The effect of ethylene chlorhydrin was rather unreliable when a different variety was used or the depth of individual dor-mancy was not uniform. It was favorable in some cases, harmful or indifferent in other cases. The appropriate duration of the temperature treatments had not been thoroughly ascertained. In this experiment, the shortest effective period of temperature treatment was studied for the corms which had been dug in the summer. The variety “Radiance” used in this experiment was the same as in the previous report. The results of the present study are summarized as follows: (1) The most successful treatment for the breaking of the dormancy was high temperature (35-38°C) storage in dry condition for 10_??_15 days followed by low temperature (1°C) storage for 10 days: (2) The high temperature (38°C) storage in moist condition was dangerous, in that decayed corms were increased. (3) The pre-cold storage followed by high tem-perature treatment was not as effective as the treatments in the reverse order. In the low tem-perature treatment, 1°C was definitely more effec-tive than 7-8°C. (4) After the temperature treatment, tetra zoliujn reaction, as an index for the redox activity, was observed on the sections of corms. Six grades of red color reaction were arbitrarily established by the writer. (5) The strongest reaction to tetrazolium was observed on the sections of corms which had been treated by the most effective temperatures for breaking dormancy. On the section of control corms, the color reaction was negative or weak.
