This experiment was caried out the investgate of productive power which had the lateral branch and main stem of cucumber. The cucumbers were made the photoperidical treatment, so that the cucumbers were promoted the occurence of lateral branch, or were inhibited. This treatments were conducted under the photoperiod condition of 8 and 14 hour, and the control plant was set under natural day condition in glass house. These results were as follows. The control plant had more yield than that of the cucumber which recieved the influence of photo-periodical treatment. The cucumber that recieved the influence by photoperiodical treatment of 8 hour showed the least yield than other. The cucumber that was set under natural day condition occured many more the lateral branch. But the cucumber that recieved the influence of photoperiodical treatment of 8 hour was very few yield. The control plant was promoted the occurence of lateral branch in consequence of the long day of spring and high temperature in glass house and was thought to lead to high yield. While, the in short day condition inhibited the occurense of lateral branch by itself and low temperature, so that the cucumber under condition of short day that had no lateral branch decreased the yield. In according, to have the lateral branch of high productive power seems to be very impotant for an increace of yield.
