Five bean cv. were exposed to natural daylength (approx. 12 h) and ambient temp., or to 6 h daylength, achieved by moving pots into a darkened room to determine their response to photoperiod. Cv. Mortino and Frijolica 0- 3.2 did not flower under the control conditions, but with the short day trea...
