| 摘 要： | 为探究多胺对硅藻生长的影响,以精胺、亚精胺、腐胺、尸胺和苯乙胺为外源多胺,对角毛藻Chaetoceros sp.、小新月菱形藻Phaeodactylum tricornutum Bohlin以及威氏海链藻Conticribra weissflogii进行室内添加培养。结果表明:同一温度下,不同多胺对不同硅藻生长存在特异性差异。亚精胺对角毛藻的生长起促进作用;尸胺对小新月菱形藻起促生长作用,而精胺对小新月菱形藻起抑生长作用;多胺对威氏海链藻生长前期(13 d前)主要起促生长作用,后期起抑生长作用(13 d后)。因此,适时适量添加多胺可有效促进硅藻的生长,提高硅藻的繁殖效率。

| Abstract: | To explore the effect of polyamines on the growth of diatoms, Chaetoceros sp., Phaeodactylum tricornutum Bohlin and Conticribra weissflogii were cultured indoor by adding spermine, spermidine, putrescine, cadaverine and phenylethylamine as exogenous polyamines. The results show that different polyamines reveal different specificity for the growth of different diatoms at the same temperature. Spermidine promotes the growth of Chaetoceros sp. And cadaverine promotes the growth of P. tricornutum, while spermine inhibit on the growth of P. tricornutum. The polyamines mainly promote the pre-growth of Conticribra weissflogii (before 13 d), and inhibit the growth (after 13 d). The timely and proper addition of polyamines can promote the growth of diatoms effectively and increase the reproductive efficiency of diatoms. |
