Both field and growth chamber grown plants show increases in plant height and pod number in the transgenic lines relative to controls. Node number, flower number, seed number, and 100 seed weight were also increased in growth chamber grown plants. Growth chamber experiments were performed in a 10:14 hour photoperiod (Light∶Dark) with 900 mE of light. Data was collected from ten plant replicates that were randomized among entries in the chamber. Field grown plants were grown under standard agronomic conditions and ambient light. All differences between the transgenic lines and control are significant to p<0.05 unless otherwise indicated as (ns) not significant.
