摘要
以盈江县澳洲坚果受害叶片为试材,采用组织分离法分离澳洲坚果叶片病原菌,结合柯赫氏法则、形态特征及病原菌ITS基因序列分析对病原菌进行鉴定。结果表明,引起澳洲坚果叶片病害的致病菌有果生刺盘孢菌、小新壳梭孢菌、拟盘多毛孢菌,其中果生刺盘孢菌与小新壳梭孢菌为当地首次报道造成澳洲坚果叶部病害的病原菌。该研究结果为深入研究澳洲坚果叶部病害发生流行规律及科学防控提供理论支撑。
The research utilized damaged macadamia leaves from Yingjiang as test materials,and employed tissue isolation to separate the pathogenic fungi from the macadamia leaves.The pathogenic fungi were identified based on Koch's postulates,morphological characteristics,and analysis of the pathogenic fungi's ITS gene sequence.The results indicated that the pathogenic fungi causing macadamia leaf disease include Colletotrichum fructicola,Neofusicoccum parvum,and Pestalotiopsis sp.,among them,Colletotrichum fructicola and Neofusicoccum parvum are the first reported pathogens causing foliar diseases in macadamia nuts in the local area.The research results provide theoretical support for further research on the occurrence and prevalence of macadamia leaf diseases and for scientific prevention and control.
