| 中文摘要: |
| 为了明确新疆阿克苏、和田地区不同枣树品种上枣果黑斑病的发生情况和病原菌(Alternaria alternata)对不同枣树品种的致病性差异，本研究采用五点取样法调查了该病害在田间枣树不同品种上的发生情况, 并在室内采用菌饼、孢子悬浮液和菌丝等3种接种体对离体枣果进行致病性测定。田间调查结果表明:枣果黑斑病在‘骏枣’和‘壶瓶枣’上发生最为严重, 发病率均高于30%; 在‘圆脆枣’、‘马牙枣’和‘酸枣’上未发生。室内优选菌饼作为接种体对离体枣果的致病性测定结果显示, 病原菌对‘骏枣’、‘壶瓶枣’的致病性最强, 病情指数≥40, 对‘灰枣’、‘冬枣’、‘赞皇枣’和‘马牙枣’的致病性最弱。研究结果为枣果黑斑病抗病品种的选育提供依据。 |
| 英文摘要: |
| The objective of the study is to elucidate the occurrence of jujube black spot and the pathogenicity of Alternaria alternata on different jujube varieties in Aksu and Hetian. The occurrence of jujube black spot on 13 jujube varieties were surveyed by sampling in five locations, and the pathogenicity of A. alternata was investigated by agar disk containing mycelium. The results showed that the occurrence of the disease on ‘Junzao’ and ‘Hupingzao’ were the most severe in the field, with an incidence of more than 30%; the disease did not occur on ‘Yuancuizao’, ‘Mayazao’ and ‘Wild jujube’. The pathogenicity of A. alternata on the fruits of ‘Junzao’ and ‘Hupingzao’ were much stronger, with a disease index ≥40，while the pathogenicity on ‘Huizao’, ‘Dongzao’, ‘Zanhuangzao’ and ‘Mayazao’ were very weak. The results may provide a theoretical basis for the selection of jujube varieties resistant to black spot disease. |
