| 柑橘是我国南方重要的水果之一, 柑橘黄龙病和柑橘病毒病已经对我国柑橘的安全生产造成了严重威胁。为了解柑橘黄龙病和病毒病对海南柑橘产业的危害情况, 本研究通过荧光定量PCR(Quantitative PCR)和反转录PCR(RT-PCR)分别对随机采集自海南柑橘主产区澄迈县3个福橙种植园和琼中县4个绿橙种植园共计109个样品进行了柑橘黄龙病和柑橘5种主要病毒病的检测。结果表明: 澄迈县福橙标准化种植示范基地和琼中县营根镇绿橙种植园2个新植橘园的柑橘黄龙病发病较轻, 检出率仅为8%和11%, 而其他5个橘园的柑橘黄龙病检出率均在75%以上, 严重的达100%。除此之外, 7个橘园均未检测到柑橘褪绿矮缩病毒; 澄迈县和琼中县的衰退病毒病检出率分别在52.9%和77.8%以上, 黄脉病毒病在83.3%和90%以上。澄迈县还检测到碎叶病毒病的存在, 检出率在38.1%以上, 除红湖农场外还存在裂皮病毒病, 检出率在11.8%以上。琼中县的绿橙种植园3还存在裂皮病毒病, 检出率为43.8%。综上所述, 柑橘黄龙病和病毒病已经严重威胁到海南省福橙和绿橙主产区的柑橘生产安全。加强对海南柑橘苗木安全生产的同时, 亟需采取有效的田间综合防控措施, 以促进海南柑橘产业的健康发展。 |
| 英文摘要: |
| Citrus is an important fruit in south China, but its production has been seriously threatened by Huanglongbing (HLB) and several virus diseases in recent years. To reveal the influence of citrus diseases on citrus industry in Hainan province, a total of 109 samples collected from three Citrus reticulata var. ‘Fuju’ orchards in Chengmai county and four Citrus sinensis var. ‘Lvcheng’ orchards in Qiongzhong county were subjected to detection of HLB and virus pathogens using Quantitative PCR and RT-PCR. The results showed that among the seven analyzed orchards, the two new orchards (1/2-year-old) were only slightly affected by HLB, with an incidence of 8% and 11%, respectively, while in the rest five relatively old orchards 75% to 100% trees were affected by HLB. Among the analyzed virus diseases, the pathogen of Citrus chlorotic dwarf associated virus (CCDaV) was not detected. In Chengmai orchards, Citrus tristeza virus (CTV), Citrus tatter leaf virus (CTLV) and Citrus yellow vein clearing virus (CYVCV) were all detected, with an average incidence of 52.9%, 38.1% and 83.3%, respectively. Citrus exocortis viroid (CEVd) was also detected in two of the three ‘Fuju’ orchards, with an incidence of 11.8% and 71.4%, respectively. In the four ‘Lvcheng’ orchards in Qiongzhong, CTV and CYVCV were both detected, affecting more than 77.8% and 90% plants, respectively. CEVd was only detected in one ‘Lvcheng’ orchard (43.8% detection rate). According to our investigation, both HLB and several virus diseases have been pervasive in Hainan province and become a great threat to the citrus production. To promote the healthy development of citrus industry in Hainan, besides guaranteeing the use of pathogen-free citrus seedlings, combined strategies to prevent the spread of citrus diseases in the field are urgently required. |
