Abstract: 本研究以海木耳 (Sarcodia suieae) 作為實驗對象,將其個別培養於不同光照(45.50、99.09、126.96及164.22 μmol photon /m2/s)、溫度 (15、20及30°C) 以及NaHCO3濃度 (0、0.1及0.2 mol /L) 環境中6小時,發現在0.2 M濃度之NaHCO3環境中,基礎生產力最大值會隨光照增強而增加 (p<0.05);反之,在0 M濃度之NaHCO3環境中,其基礎生產力最大值則隨照度減弱而增加 (p<0.05)。而在不同溫度環境中,海木耳基礎生產力也有顯著差異,在15及20°C條件下的組別在其基礎生產力最大值隨著照度減少而增加 (p>0.05);而在溫度30°C的條件下,基礎生產力最大值則隨著光照增強而增加 (p<0.05)。海木耳葉綠素含量方面在各個照度之間沒有顯著差異 (p>0.05)。 海木耳之光合作用速率也會因不同環境因子而有所差異,整體而言,在0 M NaHCO3濃度環境下溫度30°C條件下的組別其光合作用速率顯著高於15及20°C (p<0.05),而溫度20°C組別的光合作用速率則是在0.1及0.2 M NaHCO3濃度環境中顯著高於15及30°C的組別 (p<0.05),但當NaHCO3濃度、照度及溫度均到達本實驗中最高強度時,30°C的海木耳其光合作用速率則為所有實驗中最高的組別。
Studied on the optimum primary productivity, photosynthesis rate and chlorophyll-a contents of Sarcodia suieae , which was cultured in different illuminance (45.50, 99.09, 126.96 and 164.22 μmol photon /m2/s), temperature (15, 20 and 30 °C) and NaHCO3 concentrations (0, 0.1 and 0.2 mol/L) for 6 hours. In ambient of 0.2 M NaHCO3 concentration, the maximum value of the optimum primary productivity had significant increased with increasing of illuminance (p<0.05); on the contrary, In the 0 M NaHCO3 concentration, the maximum value of the optimum primary productivity had significant decreased with increasing of illuminance (p<0.05). The optimum primary productivity of S. suieae was also had significant difference among different temperature environments. The maximum value of the optimum primary productivity had significant decreased with increasing of illuminance at 15 and 20°C (p<0.05), the maximum value of the optimum primary productivity had significant increased with increasing of illuminance at 30°C (p<0.05). With different illuminances, there was no significant difference in chlorophyll-a contents of S. suieae (p>0.05). The photosynthesis rate of S. suieae had significant difference in various environmental factors. Overall, the photosynthesis rate is the most stable at 20°C in various illuminance and NaHCO3 concentration environment. However, the photosynthesis rate has the highest maximum value at 30 °C ,0.2 M NaHCO3 concentration and 164.22 μmol photon /m2/s in this experiment.
