| Abstract;Photoperiodic responses of two determinate type of Japanese soybean cultivars (Akishirome and Akiyoshi) were studied. Plants were grown at three simulated photoperiods (8h, 12h and 16h) and in natural day length conditions. Plants grew taller in longer photoperiods in both Akishirome and Akiyoshi. Plants produced fewer branches in photoperiods longer than natural day length. Length of branches per plant increased in longer photoperiods up to the natural day length in Akishirome, which was decreased at 16h light. But in Akiyoshi, branch length per plant continued to increase significantly until 16h of light period. Flowering was significantly delayed when the photoperiod was longer than 12h. But at 16h photoperiod, cultivar Akiyoshi had no flower at all. Number of flowers per plant increased up to the natural photoperiod. However, these two cultivars showed somewhat different responses in relation to their ecotypes to adapt when grown at photoperiods longer than 12 hours. (author abst.) |
