| 摘 要： | 目的]明确广西蔗区主要真菌病害的发生情况和种类,为甘蔗病害综合防治提供科学依据.方法]2009~2011年采用随机踏查、种植户随访、资料查询和定点调查等方法对广西蔗区甘蔗真菌病害种类及发生程度进行调查,并采集病害样本,通过病原分离培养鉴定等方法确定真菌病害的种类.结果]共采集和鉴定出13种主要真菌病害,分别为:黑穗病、凤梨病、梢腐病、锈病、叶焦病、赤腐病、轮斑病、褐条病、褐斑病、虎斑病、白疹病、眼点病、黄点病,其中发生严重并对甘蔗品质和产量影响最大的病害有黑穗病、锈病、梢腐病和凤梨病.结论]黑穗病仍然是对甘蔗危害最严重的病害,生产中急需选育高抗且综合性状优良的甘蔗品种以替代现有的感病品种.

| Abstract: | Objective]The purpose of the present study was to determine the species and the occurrence status of major sugarcane fugal diseases in sugarcane plantation areas of Guangxi in order to provide scientific references for controlling sugarcane diseases.Method]In 2009-2011,species and occurrence degrees of major sugarcane fugal diseases in sugarcane plantation areas of Guangxi were investigated through randomized surveys,farmer interviews,literature references,and location investigations;diseased sugarcane samples were collected and their species were identified through pathogen isolated culture and other relevant methods.Result]Thirteen species of fungal diseases were identified,which were Thielaviopsis paradoxa(de Seynes) V.Hohnel,Ustilago scitaminea Sydow,Fusarium moniliforme Sheldon,Puccinia melanocephala H.&P.Syd.,Stagonospora sacchari Lo et Ling,Colletotrichum falcatum Went,Phyllosticta saccharicola P.Henn.,Pellicularia sasakii(Shirai) Ito,Elsinoe sacchari L.,Helminthosporium sacchari(Breda de Haan) Butler,Mycovellosiella koepkei(kruger) Deighton,Bipolaris stenospilum(Drechs.) Shoem.,and Cercospora longipes Butler.Out of all of the fungal disease characteristics,smut,rust,tip rot,and pineapple disease were the most rampantly detrimental to sugarcane quality and yield.Conclusion]Ustilago scitaminea Sydow turned out to be the most serious sugarcane disease;it is urgent to begin breeding highly-disease-resistant sugarcane varieties with elite field and environment adaptations to replace the current susceptible-to-diseases sugarcane varieties in order to increase production. |
