摘　　要：采用3个剂量的N+对4个枣品种接穗进行注入诱变处理。结果显示,离子注入后可以对枣接穗芽体产生损伤作用,致使枣芽萌动率下降、萌动推迟、萌动期不集中,并且随着注入剂量的加大,这种表现愈加明显;对各品种处理枣头枝生长量的观测可知,除骏枣枣头枝注入N+剂量4×1016个/cm2与8×1016个/cm2间存在显著差异外,其他品种处理间都不存在差异;通过对各品种生长期的观测可知,壶瓶枣注入N+剂量8×1016个/cm2处理与对照间差异显著,骏枣注入N+剂量4×1016个/cm2与其他2个处理间存在显著差异,葫芦枣及大荔龙枣处理间不存在显著差异。等离子注入是高效的诱变育种手段,其中,壶瓶枣注入N+剂量为8×1016个/cm2处理产生了2株变异。This study used three doses 4×1016/cm2,6×1016/cm2 and 8×1016/cm2 of N＋ ions on four jujube varieties scion implantation treatments.The results showed： After ion implantation on jujube scion,bud was injured and resulted jujube scion bud germination rate decrease,germination delay and germination period postponed,and as the dose increased,these performance became more obvious;Through observation to shoot growth rate of all treatments,except for jujube of Junzao variety shoots processing significant differences showed between A and C,other varieties did not exist differences among different treatments;There was significant differences between different processing of Hupingzao variety and Junzao variety,there was no significant difference of the other two varieties in growth period between processings;Plasma implantation is an effective breeding method,in which the processing of 8×1016/cm2 treatment of Huping variety produced 2 variants.
