Culture tender leaves in culture medium of MS+2,4-D1.5mg/L+30g/L suger+0.7% agar pH5.8 for 20 days in darkness at 25℃, and then subculture to induced Ⅱ-type calli. 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%.

将心叶接种于MS+2.4-D1.5mg/L+30g/L 蔗糖，琼脂0.7%，pH5.8 培养基中25℃暗培养20d 后继代一次，诱导产生Ⅱ型胚性愈伤组织，用镊子将其夹碎成2mm2大小的小块，置入添加100mg/L AS 的根癌农杆菌LBA4404 菌液中，侵染时间为45min，共培养3 天后，转入MS+2.4-D1.5mg/L+30g/L 蔗糖+500mg/L Cef 培养基中恢复7天，再转入MS+2.4-D1.5mg/L+30g/L 蔗糖+100mg/L Cef+10.0mg/L Km 中，遮光培养20d后，置入其MS+30g/L 蔗糖+100mg/L Cef+10.0mg/L Km 分化，卡那霉素抗性愈伤组织获得率在侵染45min 时达到最大值平均为29.66%；同时以甘蔗心叶愈伤组织材料，通过循环水式真空泵，产生负压，设定不同的负压值，在农杆菌菌液中感染5min 后，在负压条件下继续侵染15min 后，筛选出抗性愈伤组织并获得转化植株，其中在负压为-0.05 时转化率达到最大值，其卡那霉素抗性愈伤组织获得率平均为37.5%。
