摘要: 为了解叶部病害与真菌区系的关系,本研究比较了山茶(Camellia pitardii)健康叶片与受灰斑病侵染的病叶在春、夏、秋、冬4个季节叶部真菌数量、种群组成和多样性特征等。结果表明:健叶真菌数量和物种丰富度在各个季节都高于病叶,健叶以叶面附生真菌Cladosporium cladosporioides和内生真菌Botryosphaeria dothidea为优势种,而病叶则都以Pestalotiopsis guepini和内生真菌Guignardia camelliae为优势种,并且健叶内生真菌的多样性明显高于病叶。

Abstract: A comparison was made of such characteristics between the healthy and the diseased leaves of Camellia pitardii as the quantity,population composition and diversity index in seasons of the year in order to understand the relationship between foliar microflora and the occurrence of camellia gray spot disease.Results revealed that the total number and species richness of endophytic and epiphytic phyllosphere fungi in different seasons were greater in healthy leaves than in diseased leaves.Cladosporium cladosporioides and Botryosphaeria dothidea were separately recorded as major epiphytic phyllosphere and endophytic fungi in the healthy leaves,wheareas Pestalotiopsis guepini and endophytic Guignardia camelliae were dominant in the diseased leaves.Whether leaves were infected by gray spot disease had significant influence on the diversity of endophytic fungi which was higher in healthy leaves than in diseased leaves.

Key words: Camelia pitardii, epiphytic fungi, endophytic fungi, pathogenic fungi, diversity
