【摘要】 棕囊藻属藻类生活史复杂、地理差异显著、游动单细胞个体微小,至今尚无明确的分类标准。在目前已报道的9个种中,Sournia(1988)认为只有两个种比较可靠,即形成胶群体的P.pouchetii(sensu lato)(包括P.globosa)和不形成胶群体的P.scrobiculata;一些学者将P.pouchetii(sensu lato)进一步细分成P.pouchetii(sensu stricto)、P.globosa、P.antarctica等3种。为方便起见,多数学者将形成胶群体的棕囊藻定名为P.pouchetii,或写成未定种的形式Phaeocystis sp.棕囊藻属分类的混乱制约了相关研究的深入。解决棕囊藻分类混乱问题有赖于新的技术和方法的使用。更多还原

【Abstract】 Due to its unusual heteromorphic life cycle, great geographic differences, and minuteness of motile cells, the taxonomy of Phaeocystis was extremely controversial, and the diverse criteria were adopted by different authors. In all 9 species reported today, only two species were recognized by Sournia et al. (1988): one is no colony-forming P.scrobiculata, the other is colony-forming P. pouchetii(here referred as P. pouchetii sensu lato). To avoid the subject, the majority of authors simply followed Sournia’s classification. But some authors preferred to divide the P. pouchetii sensu lato into 3 species: P. pouchetii(here referred as P. pouchetii sensu stricto), P. globosa, and P. antarctica. The confusion of taxonomy of Phaeocystis have retarded further studies significantly. New methods are needed to solve the problem.更多还原
