Abstract:
Uniconazole as a kind of growth retardant can inhibit the bio-synthesis of plant gibberellins in vivio and reduce the elongation speed of plant cell.To discuss the effect of uniconazole on soybean，the soybean seeds of Kennong 4 were soaked with 0，25，50，100，200 mgL-1uniconazole for 6 hours，then germinated in the artificial climate box.Results showed that the soybean germination percentage was decreased while germination potential remained stable when treated by uniconazole with concentration between 25 mgL-1and 200 mgL-1.The weight of fresh/dry root，the diameter of main/lateral root increased，while the root length/volume and number of lateral root decreasesd with the increasing of uniconazole concentration in the proceess of seed germination.When the uniconazole concentration was lower than 50 mgL-1，with the uniconazole concentration increasing，the activity of Peroxidase，Superoxide dismutase，Catalase increased，the content of Malondi-adehycle decreased.The result has further proved that uniconazole could inhibit the soybean growth，enhance the anti-oxidant activity，strengthen the ability of stress tolerance of soybean.
