Use forceps cutting the tissue to nubble with 2mm2, and put the tissue into Agrodacterium tumefaciens LBA4404 liquid supplemented with AS 100mg/L,then, co-culture 3 days, resume 7 days in MS+2,4-D1.5mg/L+30g/L suger+500mg/L cef, take to MS+2,4-D1.5mg/L+30g/L suger+100mg/L cef+10.0mg/L kanamycin culture 20 days in darkness. After that to make it polarize in MS+30g/L suger+100mg/L cef+10.0mg/L km. The percentage of km resistant callus was reached max after infection for 45 min, the average is 29.66%. Simultaneity, tender leave callus are infected 5 min by A. tumefaciens liquid in different negative pressure, and kept on 15 min in Agrodacterium tumefaciens liquid without negative pressure. Then screen out resistant callus and obtain transgenic plants. When the negative pressure is -0.05MP the percentage of km resistant callus was reached max, the average rate is 37.5%.
