摘要
为进一步探讨树种与树皮藻类物种多样性的关系,于2020年11月采集凤凰山国家森林公园6种常见树种的树皮藻类样品。初步检出3门3纲7目10科11属15种树皮藻类,种类组成以蓝藻和绿藻为主。团集共球藻(Trebouxia glomerata(Waren)Ahmadjian)、土生绿球藻(Chlorococcum humicola(N g.)Rabenhorst)和小球藻(Chlorella vulgaris Beijerinck)在所有树种上均有分布;在雪松(Cedrus deodara(Roxb.)G.Don.)和侧柏(Platycladus orientalis(L.)Franco.)这2种裸子植物树皮上未检出蓝藻。不同树种两两之间的藻类群落相似系数(S c)在0.38~0.80之间;被子植物中“粗糙”树皮树种与“光滑”树皮树种的藻类群落相似系数为0.73;具有“粗糙”树皮的被子植物与裸子植物树种的藻类群落相似系数为0.42。树皮藻类生态学研究以粗糙程度反映附着基质特征存在不足。
In order to explore the relationship between tree species and diversity of corticolous algae,the samples were collected from bark of 6 species of trees in Fenghuangshan National Forest Park in November 2020.A total of 15 species were identified which belong to 3 phyla,3 classes,7orders,10 families,11 genera.The main corticolous algae were Cyanophyta and Chlorophyta.The Trebouxia glomerata(Waren)Ahmadjian,Chlorococcum humicola(N g.)Rabenhorst and Chlorella vulgaris Beijerinck were detected on the bark of 6 species of trees.The species of Cyanophyta were not detected in the bark of two gymnosperms which were Cedrus deodara(Roxb.)G.Don.and Platycladus orientalis(L.)Franco.The similarity coefficient(S c)of algae community between different tree species ranged from 0.38 to 0.80.The S c of algae community between“rough”bark and“smooth”bark species in angiosperms,and between gymnosperms and angiosperms which are with“rough”bark were 0.73 and 0.42 respectively.There was a serious shortage in the study of corticolous algae ecology to reflect the characteristics of attached matrix by roughness.
