| Abstract: | The effects of 4,4,4 trifluoro 3 (indole 3 )butyric acid on barley seminal root elongation and nutrient uptake were studied. The results showed that TF IBA at 100 μmol／L significantly promoted the root elongation of barley seedlings while nutrient uptake decreased drastically. When barley seeds were soaked in 100 μmol／L or 1000 μmol／L TFIBA for 36 h during germination, the root growth of barley seedlings was markedly elongated, and the uptake of nutrien t was significantly promoted. |
