The results Showed that the highest transformation efficiency was obtained through the following transformation procedure: after preculture for 2 d, the explants were in fected 3 min with 50 mg/L acetosyringone and OD600=0.5 Agrobacterium culture liquid, and then co-cultivated for 2 d. Resistant shoots from leaf disks were screened on MS0.4 mg/L NAA + 100 mg/L Cef medium supplemented with 10 mg/L Km.

结果表明：2 d的预培养，OD600值约为0.5的农杆菌菌液添加50 mg/L AS，侵染时间3 min，2 d的共培养，从分化培养基获得的抗性芽在生根培养基MS+0.4 mg/L NAA+10 mg/L Km+100 mg/L Cef上进行延迟筛选，有利于获得较高的转化效率。

Factors that influence percentage of transformation including time of preculture, dipping and coculture, type and content of antibiotic, day of delayed selection culture, intension of selection were studied. The effective transformation system of "Starkrimson" was developed as follow: Leaves precultured in darkness for three days were dipped into agrobacterium suspension for three minutes, then were cocultured in darkness on MS medium with TDZ0.5mg/L and NAA 0.3mg/L for three days, and then cultured in darkness on MS medium with TDZ0.5mg/L NAA0.3mg/L and Cef 250mg/L.

通过对叶片预培养时间、侵染时间、共培养时间、抑菌素种类和浓度、延时筛选时间、不同选择压等遗传转化影响因素的研究，建立的'新红星'苹果遗传转化体系为：叶片黑暗预培养3天，经农杆菌侵染3分钟，在含TDZ0.5mg/L，NAA0.3mg/L的MS培养基上黑暗共培养3天，然后加250mg/L Cef黑暗维持培养3天，再进行Km12.5mg/L的选择压黑暗培养至抗性愈伤出现；转为光照条件1-2次的继代筛选，获得抗性芽后，进行扩繁。

The results showed that: the explants of strawberry leaves were rather sensitive to kanamycin, and the corresponding concentration of 20 mg/L could substantially inhibit the growth of non-transformed tisse and be used to screen the leaves of strawberry after transformation. Timentin at the concentration of 300 mg/L could be used to eliminate Agrobacterium tumefaciens and had minor impact on the growth of the explants. The preculture time of 2-4 days was beneficial to improve transformation frequency. Co-culture for 2-3 days not only had higher gus transient expression but also avoid the over-growth of agrobacterium. The bacterial concentration of OD(subscript 600nm) 0.4 was the best inoculum density and 10 minutes was the best inoculation time.

结果表明：草毒叶片外植体对卡那霉素较为敏感，适宜的筛选浓度为20mg/L，可明显抑制非转化组织的生长；300mg/L的羧吩青霉素可有效抑菌，对外植体生长影响也较小；预培养2-4d有利于转化；共培养2-3d有利于提高转化频率并避免了农杆菌的过度生长；OD(下标 600nm)值为0.4的菌液侵染10min效果最佳。
