M A J O R benefits to agriculture from studies of photoperiodism have been achieved in the United States. Selection of adapted varieties, planting at optimum dates, and the storage of plant materials for suitable periods at proper temperatures are but a few examples of practices related to photoperiodism. Beachell (2) , Adair (1) and Jenkins ( 3 ) have reported on the effects of various day-lengths and dates of sowing on the flowering behavior of some American varieties of rice. Most of the research on photoperiodic response of rice has been reported from Japan, India, and Ceylon. From the results obtained by Kar and Adhikari (j), Misra (6, 7, 8, 9, 10, 11) and Sen (12) it appears that photoperiodic response of rice largely is dependent upon the variety. Much more research is needed to understand fully the mechanisms of flowering in the rice plant.
