Zigongdongdou, was used to investigate photoperiod effects on the development of terminal inflorescence of soybean, plant type and agronomic traits, with emphasis on the role of long-day in the formation of raceme. The plants were treated with short-day of 12h for 13 days to induce the initiation of terminal inflorescence, and then moved to 16h long-day treatment for 0, 1, 2, 3, 4 and 5 weeks, respectively. After LDT, plants were returned to SD condition.
