Abstract: In order to explore and master the mutagenic techniques of plasma injection jujube scion, and find a new ways to breed the good crack fruit of jujube, the author used new technical means of the plasma implantation into Shanxi famous dates: Chun date and Huping date with nitrogen, argon plasma implantation for mutagenic treatment and grafting investigation. The results showed that: both nitrogen and argon plasma implantation could mutate. In the same implantation dose, the mutation rate of argon plasma treated samples was significantly higher than the nitrogen ion, the favorable variation mostly in the argon plasma treated samples, integrated treatment of graft survival rate and mutation rate factors, the author determined the nitrogen, argon two gases of jujube grafting optimal treatment dose of (6×10¹⁶-8×10¹⁶)/cm² (per square centimeter plasma), the injection rate was 10 mA×28 kV, and pulse intermittent duty cycle of 60%. The survey found that the scion after mutagenic treatment had wide range of variation, that could be summarized as growth rate, flowering and setting fruit, leaf, fruit shape, growth period (maturity). After four years of consecutive trials, it filtered out a high yield material that the results of high and low rate of fruit cracking and two materials the fertility of a delay of 10-15 days and crack fruit.
