摘　　要：为寻求选育综合性状良好的红枣抗裂果材料的新途径,利用冷等离子体生物改性装置对山西名枣骏枣、壶瓶枣和小龙枣的接穗进行辐照处理.结果表明,用氮、氩、氦3种气体离子对枣树接穗进行辐照处理,在一定辐 照剂量范围内,处理样品的嫁接成活率、萌发速度都受到不同程度的影响,并且产生了不同类型的变异植株,选出在生产上有实际意义的有利变异3个;综合接穗嫁接后的成活率、萌发速度和变异率,确定了N＋的最佳剂量范围为（200～250）W×3min,Ar＋和He＋的最佳剂量范围为（250 ～ 300）W×3min.Aimed to find a new way to breed cracking-resistant fruit materials of jujube with ideal comprehensive characteristics,we irradiated Jun date,Huping date and Xiaolong date scion by cold plasma biological reforming apparatus.The results showed that using three gases of nitrogen,argon,helium to irradiate scion jujube in a certain range of radiation dosage,the graft survival rate,germination rate of irradiated sample were subject to different degrees of impact,and produced different types of variant plants,and we selected three advantageous variant plants for meaningful production.Integrating survival rate after grafting scion,the germination rate and variation factors,we made sure that the optimal dosage range of N＋ was （200 ～ 250）W × 3 min,and the optimal dosage range of Ar＋ and He＋were （250 ～ 300）W × 3 min.
