摘要
以1959—1983年在黄海、东海和南海3次调查采集的浮游植物标本为材料，运用光学显微镜和扫描电子显微镜观察，探讨了中国近海尖刺菱形藻的种下分类问题。结果表明，中国近海的尖刺菱形藻为尖利型（Nitzschiapungensf.pungens），不同于曾引起有毒赤潮的另一个型即多列型（N.pungensf.multiseries）。
In this paper, Nitzschia pungens Grunow in three specimens sampled with phytoplankton net from the Yellow Sea, the East China Sea and the South ChinaSea during 1959—1983 were observed with light and electron microscope. Thesubspecific taxonomy of N. pungens in Chinese coastal waters was studied.The frutules examined are linear-lanceolate, acute, bilateral-symmetric, and 114.8μmlong, 4.7μm wide (mean values), and have 10-13 costae in 10μpm. There are 2 rowsof poroids, 3-4 in 1μm, in each intercostal membrane. From these characteristics,the frutules examined are identified as N. pungens Grunow f. pungens. Therefore,the species in Chinese coastal waters can be regarded as N. pungens Grunow f. pungens, but not N. pungent f. multiseries.
