| 摘 要： | 为了明确甘蔗中后期灾害性真菌病害种类及灾害特性,对云南蔗区中后期灾害性真菌病害发生分布和品种抗性进行调查鉴定,在成熟期称量和测定甘蔗产量、糖分及损失率。结果表明,云南蔗区中后期灾害性真菌病害有梢腐病、褐条病、锈病3种,梢腐病菌为Fusarium verticillioides和Fusarium proliferatum,褐条病菌为Bipolaris setariae,锈病菌为Puccinia kuehnii和Puccinia melanocephala;‘桂糖11-1076’、‘闽糖12-1404’、‘福农09-2201’、‘福农09-71111’、‘桂糖06-1492’、‘桂糖08-1180’、‘云蔗11-1074’、‘桂糖06-2081’、‘桂糖08-1589’、‘粤甘48号’、‘柳城09-15’、‘云蔗05-51’、‘云蔗11-1204’、‘福农07-3206’等新品种高度抗病。梢腐病、褐条病和锈病实测产量损失率平均为38.43%、25.6%、24.9%,甘蔗糖分平均降低3.54%、2.82%、3.11%。本研究明确了低纬高原甘蔗中后期灾害性真菌病害种类及灾害特性,为防控提供了科学依据。

| Abstract: | In order to clarify the types and damage characteristics of disastrous fungal diseases at the middle and late stages of sugarcane growth, the occurrence and distribution of disastrous fungal diseases and variety resistance at the middle and late stages of sugarcane growth were investigated and identified in Yunnan. The yield, sucrose content and loss rate of sugarcane were weighted and measured at the mature stage. The results showed that there were three disastrous fungal diseases at the middle and late stages of sugarcane growth in Yunnan, including pokkah boeng disease, brown stripe disease and rust disease. The pathogens of pokkah boeng disease were Fusarium verticillioides and Fusarium proliferatum. The pathogen of brown stripe disease was Bipolaris setariae. The pathogens of rust disease were Puccinia kuehnii and Puccinia melanocephala. New varieties, such as ‘Guitang 11-1076’, ‘Mintang 12-1404’, ‘Funong 09-2201’, ‘Funong 09-71111’, ‘Guitang 06-1492’, ‘Guitang 08-1180’, ‘Yunzhe 11-1074’, ‘Guitang 06-2081’, ‘Guitang 08-1589’, ‘Yuegan 48’, ‘Liucheng 09-15’, ‘Yunzhe 05-51’, ‘Yunzhe 11-1204’, and ‘Funong 07-3206’ were highly resistant to these diseases. The measured yield loss rate of pokkah boeng disease, brown stripe disease and rust disease was 38.43%, 25.6% and 24.9%, respectively, and the average sugar content decreased by 3.54%, 2.82% and 3.11%, respectively. This study clarified the types and damage characteristics of disastrous fungal diseases at the middle and late stages of sugarcane growth in low latitude plateau, which could provide a scientific basis for disease control. |
