This study was carried out to determine the effect of DTA-6 on abscission cellulase (AC) activity, abscission cellulase gene (GmAC) expressive, abscission of flowers and pods, and yield in soybean. DTA-6 was foliage sprayed at R1 stage on three varieties of Suinong 28, Kenfeng 16, and Hefeng 50 in 2012 and 2013. The results demonstrated that DTA-6 treatment inhibited GmAC gene expression in abscission zone of flower and pod, with the maximum reduction of 51% among three variet
