| 摘 要： | 对火龙果茎腐病进行诊断和鉴定,观察其病原菌形态及培养性状,并初步测定不同火龙果品种的抗病性及几种药剂对该病害的室内毒力。鉴定结果表明,火龙果茎腐病病原为Bipolaris cactivora,30℃为该菌菌丝生长最适温度。初步发现黄皮白肉火龙果对该菌的抗病性最强,红皮白肉火龙果次之,红皮红肉火龙果抗病性最差。供试药剂中25%丙环唑的效果最好。

| Abstract: | The stem rot disease of dragon fruit was diagnosed and the casual pathogen was isolated and identified.Dragonfruit varietal differences in resistance to the disease were investigated.The results showed that the casual agent was Bipolaris cactivora.White dragonfruit with yellow peel showed the highest resistance to the fungus,followed,in sequence,by white dragonfruit with red peel,and red dragonfruit with red peel.Eight fungicides were screened,and the result showed that propiconazole(25%EC) had the best con... |
