摘　　要：对毛白杨(Populus tomentosa Carr.)叶围煤污菌(sooty moulds)群落组成及演替进行了探讨,分析了叶面营养物及其变化。结果表明,叶面真菌的分离物密度随叶片的衰老而增加。对毛白杨叶面真菌分离鉴定,属于煤污菌有8种真菌:链格孢(Alternaria alternata),芽枝状枝孢(cladosporium cladosporioides),球孢枝孢(Cladosporium sphaerospermum),尖孢枝孢(Cladosporium oxysporum),出芽短梗霉(Aureobasidium pullulans),棕黑腐质毒(Humico'a fuscoatra),伏克盾壳霉(Coniothyrium fuckelii)和直立枝顶孢(Acremoniumstrictum)。不同生长期叶面真菌群落组成及优势种不同,叶面出现黑霉层后,以3种煤污菌为优势种,即出芽短梗霉、链格孢和芽枝状枝孢。不同的菌表现一定的演替模式,定殖及达到峰值的时间不同。毛白杨叶面含有多种营养物,其含量及组分随生长期不同而异,与叶面真菌分离物密度呈显著性相关。此外,对蚜虫的发生、叶面营养物含量、煤污菌三者的关系进行了讨论。The sooty moulds of Populus tomeniosaCarr.are studied from April to November,1987.The isolation density of sooty moulds in-creases with the aging leaves.Eight speciesof sooty moulds are determined i.e.Alterna-ria alternata,Aureobasidium pulluans,Clado-sporium cladosporioides,Cladosporium sph-aerospermum,Cladosporium oxysporum,Co-niothyrium fuckelii,Humicola fuscotra andAcremonium stricture.The population andpredominant species of sooty moulds varywith leaf growth.Analysis of phyllopherenutrient changes shows that amino acids andcabohydrates are present on leaf surfaces andisolation density of sooty moulds are correla-ted significunthy with content of nutrients onleaf surfaces.The interaction among aphids,phyllosphere nutrients and sooty moulds isalso discussed.
