THE response of higher plants to day-length, demonstrated over 35 years ago by Garner and Allard (5), has been utilized extensively in extending flowering season and increasing production of greenhouse crops, bmce the control of photoperiod is not feasible on large acreages of relatively low vaiue crops, the response of many field crops to day-length has been studied only superficially. In the case of spring wheats the manipulation of day-length has been employed mainly to induce "normal" growth of experimental material during the winter months in the greenhouse.
