The wood sawdust from Chinese fir (Cunninghamia lanceolata) exhibited stronger inhibition on the growth of Alexandrium tamarense than those from alder (Alnus cremastogyne), pine (Pinus massoniana), birch (Betula alnoides) and sapele (Entandrophragma cylindricum). The water extract, acetone-water extract and essential oil from fir sawdust were all shown to inhibit the growth of A. tamarense. The inhibition of fir essential oil was the strongest among all the above wood sources while the half effective concentration was only 0.65 mg/L. These results suggested that the fir essential oil may play an important role in the algicidal effect of Chinese fir.
来自杉木（Cunninghamia lanceolata）的木屑对塔玛亚历山大藻（Alexandrium tamarense）生长的抑制作用比来自桤木（Alnus cremastogyne）、松树（Pinus massoniana）、桦木（Betula alnoides）和沙比利木（Entandrophragma cylindricum）的木屑更强。杉木木屑的水提取物、丙酮 - 水提取物和精油均显示出对塔玛亚历山大藻生长的抑制作用。在上述所有木材来源中，杉木精油的抑制作用最强，其半数有效浓度仅为0.65 mg/L。这些结果表明，杉木精油可能在杉木的杀藻作用中发挥重要作用。
