Induction of polyploid tillered onion using colchicine and pendimethalin

The shoot tip explants of the tillered onion line Z-018 were used as experimental materials. The effects of colchicine and pendimethalin on the induction of polyploid tillered onion were studied in vitro with different concentrations and treatment time. Treatment with 250 μmol/L colchicine for 4 day...
