栽培与野放茶园茶树不同叶位真菌群落动态特征
Dynamic Characteristics of Fungal Communities in Different Leaf Positions of Tea Plants in Cultivated and Wilderness Tea Gardens
摘要
Abstract
This study systematically analyzed the impact of tea garden management modes on the spatiotemporal distribution of fungal communities by comparing the annual dynamic changes of culturable fungi in different leaf positions between cultivated tea gardens and wilderness tea gardens.Using tissue isolation combined with morphological identification,the main pathogenic fungi isolated from tea leaves were identified as Cladosporium spp.,Colletotrichum spp.,Didymella spp.,Fusarium spp.,Pestalotiopsis spp.,Alternaria spp.The distribution characteristics showed that the fungal abundance in both cultivated and wilderness tea gardens increased with leaf position,peaked at the 4th leaf,and the older leaf zone(4th-8th leaves)served as a hotspot for pathogenic fungi.Both types of tea gardens exhibited significant seasonal variations:the wilderness tea garden maintained a higher and more stable fungal baseline,while the cultivated tea garden showed greater fluctuations.Among the pathogenic fungi,Didymella spp.and Fusarium spp.were prevalent during spring and summer(April-August).The study revealed the synergistic regulatory mechanisms between leaf position status and tea garden management,providing a theoretical basis for targeted leaf-position-based control of tea plant diseases.关键词
