Abstract
Sorghum cv. Kafir 60 A (photoperiod-insensitive) and I.S. 3691 (photosensitive) are used in India to produce hybrid seeds, but flowering in the 2 cv. is not synchronized and pollination is effected artificially. In the studies reported, 1-month-old plants of both cv. were subjected for 1 h to fluorescent light at midnight for (a) 10 or (b) 17 nights. In both cv. ear emergence in the plants under (a) and (b) was accelerated, compared with control plants not subjected to fluorescent light. Time to reach 50% ear emergence in control plants was earlier by about 10 days in I.S. 3691 than in Kafir 60 A, but this difference was decreased to 3 days in plants under (a) or (b). The plant height and flag leaf area were also markedly increased in plants under (a) and (b). In another trial with cv. Karad Local, ear emergence in plants under the treatments (a) and (b) was delayed, but grain yields were markedly increased. It was thought that flowering in sorghum cv., which differ in response to photoperiod, can be synchronized by 1-h photoperiods given at night.-M.S.M.
