用温度为20℃、pH值从2—8的自然海水处理藻体20分钟后放入正常的自然海水中,测其光合作用速率。两种藻体的净光合作用速率随海水的PH值降低而降低;条斑紫菜可耐受pH值为3的酸度,而孔石莼却受到严重伤害。用pH为3的海水处理藻体,其光合作用速率随处理时间的延长而降低,孔石莼在14℃条件下,30分钟降为负值,在20℃条件下,10分钟降为负值;不同时间和温度处理的条斑紫菜均未出现负值。用pH为3的海水处理过的条斑紫菜和孔石莼,藻体放入pH为8.2的自然海水中培养7天后,条斑紫菜细胞结构正常;而孔石莼的细胞结构受到严重伤害,细胞壁分离解体,色素体破坏。
The temperature of 20 ℃, pH value of 2-8 natural seawater treatment of algae for 20 minutes after normal natural seawater, measured photosynthesis rate. The net photosynthetic rates of the two algae decreased with decreasing pH of seawater; Porphyra yezoensis was able to tolerate acidity at a pH of 3, while Aconiti karstis was severely damaged. Phytoplankton treated with seawater at a pH of 3 showed a decrease in photosynthetic rate with increasing treatment time, and decreased to negative 30 minutes at 14 ° C and negative 10 minutes at 20 ° C ; Porphyra yezoensis treated with different time and temperature showed no negative value. Porphyra yezoensis and Phyllostachys pubescens treated with seawater at a pH of 3, the algae were cultured in natural seawater at a pH of 8.2 for 7 days, and the cell structure of P. zonulae was normal. Disintegration of cell wall disintegration, pigment destruction.
