| 摘 要： | 利用交叉培养的方法,研究了球等鞭金藻与纤细角毛藻、牟氏角毛藻、新月菱形藻和三角褐指藻等4种海洋微藻间的化感作用。并利用高效液相色谱分析了这4种海洋微藻的胞外滤液萃取物。结果表明,(1)球等鞭金藻胞外滤液浓度大于40%时,显著抑制三角褐指藻、新月菱形藻和牟氏角毛藻的生长,而对纤细角毛藻的生长则有明显的促进效果,但当胞外滤液浓度大于80%时则对纤细角毛藻的生长也表现出抑制作用。纤细角毛藻、新月菱形藻、牟氏角毛藻的滤液浓度大于40%时,对球等鞭金藻表现出显著抑制作用,三角褐指藻胞外滤液浓度大于80%时才能抑制球等鞭金藻的生长。(2)4种海洋微藻胞外滤液的萃取物能明显抑制球等鞭金藻的生长。(3)纤细角毛藻、牟氏角毛藻、新月菱形藻和三角褐指藻的胞外滤液分别包含8种、5种、6种和7种物质,同时结果还表明4种海洋微藻产生的抑制球等鞭金藻生长的化感物质并不相同。

| Abstract: | Allelophathy between the four species of marine microalgae(Chaetoceros gracilis, Chaetoceros muelleri, Nitzschia closterium and Phaeodactylum tricornutum) and Isochrysis galbana was investigated using bi-algal cultures under controlled laboratory conditions.And extracts from cell-free filtrate of Chaetoceros gracilis, Chaetoceros muelleri, Nitzschia closterium and Phaeodactylum tricornutum were finally analyzed by reversed phase high-performance liquid chromatography, respectively.The results demonstrated t... |
