| 中文摘要: |
| 枣疯病是一种由植原体系统性侵染引起的病害,严重危害枣树生产。从野生酸枣疯树丛中采集无病状植株的种子或枝条,通过播种或扦插方式,获取种苗5434株。用贴病皮嫁接法接种病毒,历时6年初步筛选获得抗疯植株40棵；以此作为砧木,距地表40 cm处嫁接感病品种‘长红枣’,待粗度生长适宜时,分别在长红枣部位和砧木部位嫁接病皮传毒,历经18年观察研判,最终确定4个对枣疯病高抗或免疫的砧木株系,即90801号、90803号、90806号、908011号。将感病品种‘长红枣’分别嫁接在4个砧木上,用贴病皮嫁接法在品种部位接种传毒,抗病效果明显,并将90801、90803号砧木枝条桥接病树主干,枣疯病状逐渐减轻直至消失。因此认为：用对枣疯病高抗或免疫的种质作为砧木,可有效防止枣疯病蔓延危害；桥接病树主干具有一定治疗效果。 |
| 英文摘要: |
| Jujube witches’ broom is a destructive disease caused by systemic infection of phytoplasma and seriously hindered the jujube production. The seeds or branches of asymptomatic plants were collected from wild zizyphus jujube trees with witches’ symptom, and 5434 seedlings were obtained by sowing or cutting. Forty resistant plants were screened out by grafting the diseased bark onto the seedlings and then checking the disease occurrence for 6 years. Four strains of 90801, 90803, 90806 and 908011 with high resistance or immunity to jujube witches’ broom were obtained by simultaneously grafting diseased bark onto the seedlings of rootstocks under test and the susceptible germplasm "Zizyphus jujuba var. Changhongzao" which was grafted 40 cm away from the ground, and then checking the disease occurrence for 18 years. |
