广州市景观湖微囊藻的分类学研究

Taxonomic Study on Microcystis (Cyanophyta) from Some Scenic Lake in Guangzhou

摘要:

于2008年3月至2009年4月，对广州市区若干景观湖水体的微囊藻属(Microcystis)进行分类学研究。共观察到11种微囊藻，分别是铜绿微囊藻(M. aeruginosa Kützing)、放射微囊藻(M. botrys Teiling)、坚实微囊藻(M. firma Kützing)、水华微囊藻(M. flosaquae Wittrock)、鱼害微囊藻(M. ichthyoblabe Kützing)、挪氏微囊藻(M. novacekii Komárek)、苍白微囊藻(M. pallida (Farlow) Lemm.)、假丝微囊藻(M. pseudofilamentosa Crow)、史密斯微囊藻(M. smithii Komárek & Anagnostidis)、绿色微囊藻(M. viridis A. Braun)和惠氏微囊藻(M. wesenbergii Komárek)，对它们的形态学特征进行描述，并比较这些种类间的形态区别。

Abstract:

From March 2008 to April 2009, the morphological taxonomy of Microcystis collected from several typical scene lakes/ponds in Guangzhou was studied. Eleven Microcystis taxa had been identified totally as M. aeruginosa Kützing, M. botrys Teiling, M. firma Kützing, M. flosaquae Wittrock, M. ichthyoblabe Kützing, M. novacekii Komárek, M. pallida (Farlow) Lemm., M. pseudofilamentosa Crow, M. smithii Komárek & Anagnostidis, M. viridis A. Braun and M. wesenbergii Komárek. Their morphological characters were described and photoed under light microscope, and the morphological differences among Microcystis species were compared.
