In the northern United States and in Canada, one of the problems limiting profitable production of greenhouse tomatoes during the winter is the marked failure of fruit set. The same problem is encountered in the important tomato-producing areas in the south during the summer. In extreme cases, crop failures have been reported (Went 1957). The poor setting in apparently healthy tomato plants has been shown to depend largely upon the climatic conditions at the time of pollination. Low light intensity, short photoperiod, and high night temperatures may all be limiting factors.
