中文摘要 | 擬氣球藻(Botrydiopsis archiza Borzi),為四草濕地研究樣區最主要的優勢浮游性藻類。雙眉藻(Amphora sp.),則為四草濕地研究樣區最主要的著生性微藻。兩種不同之微藻,於實驗室以Marine enrichment medium f/2培養基在30℃及30-40 µmol光照條件下,以14小時光照及10小時黑暗的連續培養結果,可分離出純種。而以20℃和35℃等不同恆溫培養兩種純種微藻之結果,皆顯示培養於35℃之生長速度僅比20℃稍快一些而已,顯示溫度對其影響並不顯著。此外,在掃描式電子顯微鏡下觀察顯示,未經硫酸與硝酸鉀處理之雙眉藻因具許多泡狀結構,故此矽藻群聚可以以塊狀形式漂浮於水面上,在夏季雨季明顯期間,形成四草濕地樣區中最主要之泡沫狀優勢種漂浮藻。 |
英文摘要 | Botrydiopsis archiza Borzi and Amphora sp. were the major dominant planktonic and attached microalgae in the wetland of Szu-Tsao. Both of the microalgae were isolated from the nature by the Marine enrichment medium f/2 medium under the condition of 30℃ with light (30-40 µmol) supply for 14h then placed in dark for 10h Moreover, both of the isolated microalgae were cultured in different constant temperature (35℃ and 20℃) to compare the results. The results shows that the growth rate of microalgae is slightly faster under 35℃. However, the temperature was not a significant factor of their growth rate. In addition, it was found under scanning electric microscope that, the Amphora sp. which has not been treated by H₂SO₄and KNO₃consists of bubbly structure. This was the reason why the diatom assemblages form a mass of floating on the water surface during the rainy reason of summer, and became the most important dominant floating algae. |
