为给台湾青枣的栽培、引种及有效利用提供参考,以北京地区大棚栽植的9个品种为材料,分别对其抗寒性、抗虫性、丰产特性进行对比研究.结果表明:北京地区棚栽台湾青枣越冬无冻害死亡现象发生,不同品种抗寒性差异显著,其中五千种、高朗1号、大世界与碧云抗寒性表现较好;自然状态下,不同品种台湾青枣一年生枝的相对电导率随外界气温的降低而升高;各品种抗病虫能力差异很大,其中黄冠、缅甸枣、碧云和脆蜜表现较好;喷施赤霉素以后,各品种坐果率都有所提高,碧云喷施15 mg·kg~(-1)的赤霉素坐果效果最佳.

In order to provide a basis for cultivation, introduction and effective utilization in Ber (Ziziphus mauritiana Lamk), nine cultivars in greenhouse in Beijing were used as trial materials to study the differences of cold–hardiness, disease and insect resistance and cultivation characteristics. The results showed that no jujube planted in greenhouse in Beijing suffered from frost destruction. The cold-hardiness of 'Wuqianzhong','Galo','Dashijie','Biyun' were better than others under the same condition. Relative electrical conductivities of one-year-old branches were increased under natural situation when environment temperature was dropped. The disease and insect resistance of different cultivars were distinct also, 'Huangguan','Mian dianzao','Biyun' and 'Cuimi' were better than others. Gibberellins could promote the fruit setting rate of all the 3 cultivars, and 15 mg·kg~(-1) to "Biyun" got the most remarkable effect.
