BOTH the species of jute, Corchorus capsularis L. (D 154) and C. olitorius L. (C.G.), have been found to behave as short-day plants1,2. In a further investigation on the photoperiodic effect in jute, the effect of a number of light periods continuous until flowering and for shorter periods has been studied. The mean flowering time of twelve plants per treatment grown in pots and the mean heights at flowering were noted. There were two sowings—on April 17, 1948, and on June 2, 1948. Plants of April sowing were subjected to 14 days, 21 days and continuous 8 hours, and to 14 days, 21 days and continuous 10 hours treatments, and those of June sowing to 7 days, 14 days and continuous 10 hours and to 7 days, 14 days, 30 days, 60 days and continuous 14 hours treatments.
